After several delays, version 1.9 is finally out!

Here is the changelog:
# Release 1.9
* The client connects to multiple servers in order to retrieve block headers and find the longest chain
* SSL certificate validation (to prevent MITM)
* Deterministic signatures (RFC 6979)
* Menu to create/restore/open wallets
* Create transactions with multiple outputs from CSV (comma separated values)
* New text gui: stdio
* Plugins are no longer tied to the qt GUI, they can reach all GUIs
* Proxy bugs have been fixed

Thanks for the new release  :) Is it still possible to select one (or more) servers resp. to exclude a server?

you can still select the server that is used in order to know your wallet's balance and history.
the multi-server part is only for the block headers.
if the server you selected is lagging (is not on the longest chain), Electrum will either warn you, or it will switch automatically to another server, if you enabled auto-connect.

Good news, thanks :D

I recently got a new pc and wondered about how to bring my Electrum wallet from my old pc to my new one and I remember looking at your FAQ and thinking, "Jeez, what a hassle," so I ignored all that, downloaded the Electrum 1.8.1 file on the new pc, opened it, entered my seed and ka-ching! my wallet appeared effortlessly. It's a sweet program, thanks for all your hard work, it really is appreciated.

:)

A couple of issues with the Mac version:

The download link is wrong. The link points to http://download.electrum.org/electrum-v1.9.dmg but the actual correct link is http://download.electrum.org/electrum-1.9.dmg

Secondly, the menu bar in Lite mode seems to have vanished. There is no way to show the receive addresses in lite mode.

thanks, I fixed that.
in lite mode, right click will show a menu

Aha. Was it always like that? I'm sure I remember options being in the menu bar.

Apologies if I just remembered wrongly. (!)

Thanks for fixing the link.

This was indeed the case, you are not slowly turning mad. I think Thomas removed the bar from the Lite GUI to make it more Lite :)

IMHO, it made more sense to have those options in the menu bar. Mac users are not accustomed to routinely right-clicking things. The menu bar is the standard place to put things like that on the Mac.

Request for the next version:
it would be nice if we could save the addresses qr code images as we can do in Multibit (drag and drop).

actually, this is a temporary thing; the plan was to create buttons on the right and bottom borders of the UI, to expand/minimize the views.

Is there a recommended way of updating on Ubuntu? And how to update on an offline Ubuntu?

 

How do I update my Ubuntu version I downloaded from the Ubuntu software center? Also how come on your site there is no Ubuntu version?

Great! Unfortunately http://electrum-desktop.com/ isnt reachable for me... are downloads happening directly from that domain so that its maybe overloaded?

I use electrum.org and downloaded from there today without issues.

where is that url still advertised?

4 times in this active thread (who is Electrum user?) https://bitcointalk.org/index.php?topic=100502.0

I have OSX 10.9. Used 2nd link above. Copied Electrum.app out of dmg to Applications, tried to open, got:


Repeated steps above, same error.

Tried to open within dmg as well, said it was damaged too.

ETA: OSX lies about it being damaged on first run if you don't have this set:

Change System Preferences: Security & Privacy: General: Allow applications downloaded from: Anywhere.

Always used it. But the new website is opening...

Have just downloaded, opened DMG, double clicked it and it is working (Mac OS X Mountain Lion). Also have it on Mavericks

OSX lies about it being damaged on first run if you don't have this set:

Change System Preferences: Security & Privacy: General: Allow applications downloaded from: Anywhere.

Where to get the locale for the portable version. The old seems not to work.

I would like to see in a future version that after switching freeze or prioritize on an address that the whole list isnt painted new and i have to scroll back to the bottom to move forward, maybe having to open the second tab again too.

Nice would be to be able to select a couple of addresses and switch status too.

At the moment its not really fun working with a wallet that has many addresses already. There is a timed redraw too that stops everything, repaints and goes to the start of the list. Then i have to go to the bottom again and forward with what i did.

Any reason why version 1.9 keeps hanging on Win 8.1?

Despite opening and closing and repeatedly checking to ensure that the program has net connectivity, it's been saying "Not connected" in the bottom left corner (after working effectively for a day or so) and it's showing a red circle in the bottom right corner (after seemingly previously functioning properly with the green dot).

I'm over waiting for it and have managed to find my old set up files of 1.8.1 and will be going back to that, staring at a red dot when I want to transact just doesn't do it for me.

Thought I should let you know, it could be user error, just I'm not sure what I'm doing differently than I did when it worked  ???

Cheers.

:)

click on the red dot. enable auto-connect. click OK

Thanks. Auto-connect was enabled. Internet connectivity is normal, version 1.8.1 seems to be working but not 1.9.

I found some old seeds I had when I first started messing around with Electrum; is there any way to find out if there is anything on them without having to re-install?

no you have to reinstall (unless you want to give the coins away)

if you click ok, it should work.
otherwise, try to select a server manually...

I honestly can't remember, but I think I had like 9 or so. xD

[edit]: Turns out I had 9 BTC at once on there, but only had 0.01 left over. :(

Thanks for your assistance, much appreciated.

I've clicked ok, that was your first instruction, I've also selected a server manually, doesn't work either. It doesn't seem to make sense, perhaps the application has become corrupted somehow so I'll download a clean install from your site and see how that goes. I'll edit this post with the outcome in a couple of minutes. Thanks again for all your help.

:)

-------

Edit: Ok, downloaded the Windows exe and it at first it didn't connect, auto-connect was not checked on install. Checked it, seems to be working fine. There's a difference between this version and the one I downloaded a day or so ago, at least cosmetically, as the icon is not a standard bitcoin B in blue, this new icon is a blue B enclosed in a geometric shape.

Anyway thanks for your help, maybe the original version was tweaked somehow or maybe it was corrupted on my end.

Good luck with it all.

;)

Additional edit: This second 1.9 version has now disconnected after less than ten minutes and won't reconnect to any servers automatically or manually. I'll go back to 1.8.1  :-\

Nevermind, it was a plugin lol

Hi, thanks for the update. Was wondering where the dollar value went though? Why did you get rid of it? It was on the bottom left right next to BTC amount.

It is a plugin now. See Menu Tools -> Plugins -> Exchange rate
Electrum can integrate third party applications as plugins.

Is there a secret to getting the window and column sizes to stick in v1.9? They go back to default after I change tabs or close and reopen the program. In v1.8.1, the sizes and positions are saved automatically. I'm using the portable version on Windows 7.

Also, 1.9 is connecting to random servers no matter what I do. Is this by design? I'd like to be able connect to the same server every time.

Thanks

im literally raging right now

why cant this goddam electrum  not connect always have the damn red spot

tried all possible connections and it keeps on failing
it was all fine until that stupid update wrecked my nerves


so I just tried the old version and boom
it connects but gives me a "$==)§=§%nwfw"  faiure notice when trying to send my BTC

EDIT: the old version just sent the BTC praise the lord !!!

Yep, exact problem I mentioned above, thanks for mentioning this, glad to hear it's not just me having these issues.

Will autoconnect take the SSL-Setting into account? It wont connect to a non-ssl-server?

Something i dont like is that its somehow really hard to make electrum store the windows and table settings. I make the window like i want it, close and reopen electrum and everything is back to default. I change the tables to have more space for the label, edit something and electrum redraws the table, sets me to the start and my changes to columsizes are gone again.

are the connection problems encountered with portable builds?

Scratch that. None of the settings are saving. Not the zeros in the settings, language, plugins...nothing. Reverting to 1.8.1.

ok, if you are reporting a regression, please mention if it occured with the "windows portable" build

I use the portable windows build and it seems nothing is stored. Even more. It seems like everything was set back to default after starting 1.9. currency, language and so on.

I just made 1.9.1 packages, that fix a few regressions: --offline mode, portable mode.
I hope we will soon have binaries from Animazing.

I also temporarily removed the portable build from the website; it was broken.
apologies for the mishap; I hope we will soon have a fixed build

For those of us who use the Ubuntu version is it ok using the older version since theirs no new update for Ubuntu? Will using the older version on Ubuntu cause any security issues?

All latest versions works on Ubuntu. Do you mean the slowaes error while installing in Ubuntu 13.10?


https://bitcointalk.org/index.php?topic=315815.msg3390829#msg3390829

Electrum 1.8.1 works for me, but 1.9 connects, sync's once and then drops all its connections for no reason. It doesn't matter what I do afterwards. Yes, I have deleted the BlockChain headers and all the other file, no my Firewalls doesn't block it. Nothing helps.

bitcoininformation, have you tried uninstalling it, removing any trace (from appdata if windows), and reinstalling it and restoring it through the seed? That worked for me when I was having problems with the connection.

Not the smoothest of upgrades, that's for sure. Takes a little of the shine off the venerable Electrum  :-\

Looks like it's back to QT and time consuming blockchain downloads. 

I keep getting pending transactions even though they have clearly have many confirmations on blockchain, I reinstalled and it was temporarily fixed but now it's happening again. Any advice?

Hm, no I did not. Will try that.

indeed, sorry about that.
we are actively working on these issues, and I hope we'll get better binaries next week.

Thanks Thomas.
What about supporting multi wallets? Is it hard to implement? I really have enough of Multibit, it is slow, memory hungry, and full of glitches.

Please add HTTPS support to the download page of electrum. (download.electrum.org)

Or just only for the PGP signature of the downloads and the developers.

Hey,

I upgraded my watchonly wallet to 1.9.2, tried to send some coins,
but I could not sign the transaction on my offline pc (older electrum 1.7.1)

Error Message on the offline pc was:
exceptions must be old-style classes or derived from BaseException, not Nonetype

After downgrading the watchonly wallet to 1.8.1 it works again.
Not sure if this is a bug or if I just need to upgrade the offline electrum (too lazy right now, it is a live cd)

I've an interesting problem here, seems relatable enough to the 1.9 upgrade so I'll post it here. I've got an Electrum wallet made with 1.8.1 that I've lost the seed for, and I've also spent the last week trying to remember what my password was.

When the 1.9 update came I was still at it trying password combinations, when EUREKA! One of them finally worked. Seems I capitalized TWO extra letters. Or so I thought...

When I clicked the little seed icon and entered in the password, there was an empty space where it should have been showing me the seed. I clicked on the padlock and changed my password to empty spaces to decrypt the wallet. I opened it up in notepad and here are some snippets:

'use_virtualkeyboard': False, 'use_encryption': False, 'labels':...

                               
...'classic_expert_mode': True, 'seed': '', 'accounts':.....



Ok, so the seed's gone. I checked the backup of the file I'd just opened. Saw this:


{'use_virtualkeyboard': False, 'use_encryption': True, 'labels': ....

 'classic_expert_mode': True, 'seed': '*******************************************************************************************==',....


Ok, so the original file did have a seed in it and it was encrypted. I thought maybe it might have been an issue with 1.9+, so I opened up the wallet in 1.8.1. Tried the password that decrypted it in 1.9+....Invalid. Wtf?


I've tried everything I possibly can to get this money out. Using 1.9+ after decrypting with the password: I can export all the key pairs, but importing them into another wallet doesn't give me the coin or the same address. Send leads me to the offline transaction mode, but I'm unable to sign the transaction.

What is the connection between this passphrase and this .dat file, when it doesn't even work in the original build that I generated the wallet in? I'm pulling my hair out on this one, the amount of money in there isn't chump change for a guy like me who lost his job and is late on rent.

More pertitent info:

- Original wallet generated with the 1.8.1 python build in a Debian VM.

- Seed backup that I always make is definitely nowhere to be found, spent the first three days covering those bases.

- In windows I've tried with 1.9 portable & .msi / 1.8.1 portable, same results.

- If it turns out the the password that decrypts with 1.9 isn't the "real" password, I've got a good enough idea about what the password might be to make brute force a plausible solution, it wasn't a hashed password or anything like that.

- Aye thar be bounty for whoever helps me get my money (watching the dollar value rise in the wallet the last week has been bitter-sweet to say the least).

I have noticed that there isn't a tray icon for Electrum Portable (Windows 7 x64), so it just shows an empty spot (this also happened with 1.8.1).

Same connection problem here.

Installed via pip.

edit:
Was able to get connection by playing with auto connect setting, exiting and reenter a few times.

Is there anything I can try typing in the console when it does it again to help diagnose the problem?

It is already in the code, but the priority now is to fix those errors, so you won't need to wait much if that matters :)

Cool! Will patiently wait!  ;D

http://misatkes.com/anxiety.gif

First, thanks for Electrum...i like the software the most. I have a question and please forgive me if it is already has been answered. But is there a possibility to live update the EUR/USD instead of closing the app and start it up again?

What would your use-case be? Why not simply go to a chart site if you need up-to-date information?

That is what i do now yes, but it would be a great future for Electrum to implement that in the program.

It's not meant to be a chart application but a wallet application. Although I guess we could build in a timer that refreshes the rate. You better open a ticket at Github for a feature request :)

Thanks :)

I have a small question: when i import an address it warns me that it will not be backup in the seed so also not being recoverable. But what if i let other do a payment on that address, will the coins be there after a recovery? Or do i have to import the address again to see the coins again?

You'll have to import the address again. The seed only recovers your determinstic keys and has nothing to do with any key or address that you import later.


I also have a question: I am still on version 1.7.x...: Does the latest version (or already 1.8.x?) have the possibility to sort alphabetically by address, or sort by amount, or sort by label, when viewing my own Receive addresses (or my address book), ... or even a search function?

This would help me a lot in getting organized... and would be the main reason for an upgrade - otherwise I am fully satisfied with 1.7.x and "never change a  running system".

We just released version 1.9.4, with binaries for mac & windows.
This should fix the various bugs reported since 1.9 was launched.

But the coins stay in the wallet i guess, sorry, just want to be sure lately :)

A tray icon, yeah! Not having one annoyed the hell out of me, haha. I still don't like the design of the new menu's, but oh well, everything seems to work now and that is the most important thing. :D

How to verify signed binaries:

Wrong terminology. Are you familiar with the basics of bitcoin?

Only FIAT coins and banknotes can reside inside a wallet.
For "Bitcoin", the wallet contains private keys, not "coins".

Coins are associated with a bitcoin address, as is recorded in the public ledger, the blockchain. You can only access coins associated with an address if you have the private key of this address. The WALLET is a computer file that contains one or many private keys (or in case of electrum a private seed from which the electrum algorithm can calculate all your determinstic private keys and their addresses).

Your original wallet contains the determinstic keys PLUS your manually imported keys/addresses, after you have imported them.
But after you recover your wallet from seed, this will only recover your deterministic keys, not the imported keys/addresses (because they have nothing to do with the seed), so they will not be in the wallet.

I think I cannot explain it any better.

Just download portable version 1.9.4 on Win7-x64

I got a small problem when I try to change the field "Display zeros". I set it to "8", and click ok. Right after, all my balance is shown with 8 digits after the decimal point.
However, upon closing and restarting Electrum, it turns back to the original setting (no digit after decimal).

Could someone please check if they can replicate the same problem?

Thanks.

any docs for plugin dev? :(

The code itself ;)

So I am updating from the 1.8 branch and have a few questions:

- Where do you toggle between expert mode and normal?

- Gap limit option has been removed, right?

- The copy option under the file menu is the new way to backup the wallet?

- Default wallet has been moved under wallets directory. But what about other wallets? They open fine but I want to know whether they will be "upgraded" in future?

edit: The new send many feature is really awesome!

no more. everybody shares the same user experience.

it has been hidden. it was unnecessarily complicated for normal users, and it is not a good method for merchants.

yes

they will still be supported. you may move them to your wallets directory

Thanks ThomasV.

Has something happened to the contacts list in 1.9.4?
I have only a tab with an empty list, no controls to manage contacts, no right click. I have labeled a few outgoing transactions, they show with labels in the history tab, I also just made a transaction and gave it a label immediately when sending in the send dialog but absolutely nothing is showing up in my contacts list.

I tried exporting labels, the file corectly contains labels for the addresses, I tried re-importing that file, still no contacts list.

Edit: Found it in the wallet menu. (I'm a new user since 1 week)

A few suggestions:
* please make "add to contacts" an Option the context menu in the history tab
* please make it add the contact automatically when sending
* please add a context menu to the **empty** space in the contacts tab for "add contact".
* Its throwing a lot of exceptions to the console on startup and also during shutdown.
* there is no way to disconnect/reconnect, the network dialog is confusing, what is the "auto connect" option and the list of servers good for if I cannot choose one of them to connect manually?

* I'm a new user, so the above might sound stupid but that are the problems I was immediately confronted with. There are a few more things regarding the user interface that don't seem to be how I would it expect to work but that might better fit into another post.

It already does this.


In the network dialog uncheck auto connect option and then you'll be able to choose a server you like. You can also bring up this dialog box using the green/red icon in the bottom right.

Wallet > New Contact

yes, but doing it with a single click instead of having to switch around and copy paste would be easier. There is already a context menu with some items for things to do with the transaction like "show details" etc. and "add to contacts" would naturally belong in there too. Maybe I should submit a pull request.

Then I have found a bug because it did NOT do it. Otherwise I would not have had an empty contacts list after my last outgoing transaction.

I agree

Here is some more information:

* I had experimented with creating new empty wallets, restoring from seed, etc and then deleted the additional wallets again. Maybe at this time i also accidentally deleted the old contacts list which had contained exactly one entry, namely "MtGox"?

* then the next day I saw that 1.9.4 was available, I installed 1.9.4 over 1.9.2 with pip as described on the download page.

* I started electrum, everything was fine, my wallet and transactions showed up normally, the only outgoing transaction was still labeled "MtGox" but my contacts were empty!

* Then I made another transaction to the same address and labeled it identically "MtGox" and it did not add MtGox to the contacts list, contacts was still empty, however it showed up as "MtGox" in the history list. Could this be because it first checked the existing address labels in the history instead of checking the contacts list for existence of this address/label and then decided to not add it? IMHO It should add it to the contacts list if its not in the contacts list already and not use the existing history labels for this decision.

Good idea.  All software should be downloaded with https or at least have PGP signatures.  All devs should subscribe to Security Now (Podcast).

A bit problematic though, arguably a man in the middle, MIM, attacker could give a false public PGP key.  The devs public keys should be distributed over https.  There is also an issue in switching from http to https.

[quote SecurityNow Episode 403]
The problem is that they're initially able to make a connection that is not secure, and a man in the middle could, and we've talked about this before, could arrange to strip off the HTTPS outbound query, changing it to HTTP in order to still try to make the service usable.
[/quote]

So a MIM attacker that sees index.html over http could change the https links to http.  So, instead of downloading the PGP key over https it will come down over http which could actually be any key the attacker wants to substitute, such as one he creates himself.  This holds for signatures too as well as the binaries and that could be modified to be a trojan horse.

 I entered my master public key on a separate internet connected computer to create a watching only wallet, but if I right click on a public address and click on "private key", I can see the address's private key without it asking me for my password.  Am I wrong or is this in effect no different than having an unencrypted wallet? If someone could hack into my computer, they could see the private keys for all my addresses.  Until this is clarified, I have transferred all my funds out of electrum wallets for the time being (though electrum is otherwise great).

Does this happen to anyone else?

I guess you are talking about the wallet that has your seed (not the watching-only wallet), and that you forgot to encrypt it.
just add a password..

or maybe you selected 'restore from seed' and typed your master public key there

Nope.  It is my watching-only wallet on a computer that has never had a hot wallet on it.  I even erased the watching only wallet, reentered my MPK and it still happens.  However, I compared the private keys shown on the watching-only wallet to the cold storage wallet the private keys are different.  Could a dev or someone explain what is going on?  Does this mean I am okay?

you definitely selected 'restore from seed' instead of 'restore from master public key', and typed your master public key there

No I definitely didn't either time, both times it said "watching only wallet" after it was created, and I can only create unsigned transactions.  Let's just take my word for it that I entered it in the correct place, what should be happening when I click on private key?  I'm on OSX Mavericks if that is of any help.

I'm on Mavericks and I can't reproduce what you are seeing. I've created a fresh wallet, then restore from its MPK and it doesn't appear to have the private key option as expected.

Then restore using the MPK entering it in the seed section and got a different set of a addresses, that obviously carries privkeys.

That is so odd.  When I create the watching-only wallet, I get the correct set of addresses.  What should I do?    

Hi dear people,

is it possible to update electrum from 1.7 to 1.9?
I mean, I'm a bit afraid of downloading a new version and not knowing how to transfer my wallet there.

If there is no other options than anew download, do I have to delete the old version first?

Basically I would not touch anything if I didn't have any problems but I have: the application is stucked on synchronizing so I cannot do anything.

So question 1: would a new version solve my problem?
question 2: how do I process, "step by step".

I'm on a mac book with lion.
THANKS,
Neotenie

Step 1. Download the Application from the website and drag it to your applications folder.
Step 2. You are done.

:)

Thanks Tashikoma,

to be clear:

when prompted when dragging the new software to the application folder with "replace with the new one or keep both" I shall choose to replace the old one, yes?
Will the program recognize my wallet automatically?

Greets,
Neotenie

Replace / overwrite

Tachikoma, you never expected that :D

Hi people,
I didn't get the insider joke but thanks!
Neotenie

The only insider joke I'm interested in is "the new version of Electrum is working perfectly and safe for everyone to download".

Wait... is that a joke?  :D

I'm hoping it's not a joke, this upgrade has gone on far too long and I'm getting somewhat bored looking at the arcana on this thread.

Best of luck with the upgrade though, I'll check back in to see if 1.9.4 is actually gonna fly or whether people looking for a best-of-breed straightforward wallet like Electrum 1.8.1 are still expected to become involved in its development and testing.

 :-\

Is it possible to increase the gap limit manually by editing the wallet file or is that unsafe? I am running out of free addresses and would rather not resort to a php script to generate more from my mpk.

edit: What I've tried so far without success:

- Tried an electrum.conf file https://github.com/spesmilo/electrum/blob/9ce90932ba6ca7f474f1d7bbae08bffaf28d842e/electrum.conf.sample

- Tried the -G command line switch. This works when creating new wallets but not with old ones.

in the python console, you can do:


it will create a new address, beyond your gap limit.
(you might need to restart the client to refresh the display)

Ok I did that. Thanks. But it displays red in the label column next to those new addresses. That isn't going to be a problem, is it?

red means that the address is beyond the gap limit, so it will not be recovered if you restore from seed
the red color will disappear once other (preceding) addresses receive coins.

Ok thanks again.

I am trying to upgrade from 1.8.1 portable to 1.9.4 portable using seed. The gap limit was set higher than normal in 1.8.1 (required for an application using the master public key) and to recover all addresses I need to increase gap limit in the 1.9.4 version (Windows) or I will lose transactions. I need to set the gap limit in 1.9.4 the same as is was in 1.8.1.

How do I increase the gap limit in 1.9.4 portable in Windows? The option no longer exists in GUI. I sure hope you did not take that capability away, that would not make sense and is a big headache for me.

Yes he did take that capability away in the GUI. But what you can do is to run Electrum with the -G switch:

electrum -w mynewwallet.dat -G 10

(The -w part is optional if you don't have a default wallet)

This only works with new wallets and I guess with wallets you are restoring from seed.

For an existing wallet you have to do this:

https://bitcointalk.org/index.php?topic=324614.msg3604327#msg3604327

Thanks, but not working. Need to hear from the developer.

I just tried it and it works fine. You need to specify a custom wallet file using the -w option and a gap limit using -G. So for a new wallet file test.dat with a gap limit of 100 it would be:

electrum -w test.dat -G 100

I can also just use 1.9.4 and select file > open and use the wallet.dat file from my old version 1.8.1. What ticks me off is the arbitrary change in 1.9.4 removing expert mode so I can no longer set the gap limit where I need it. Bring back expert mode please.

Alright, I got the same problem as before, which is that Electrum disconnects randomly. If I select a different server, it will be connected again for a while after which the whole cycle starts over again.

 Agreed

I am stuck using 1.8.1 unless developer brings back option to adjust gap limit. I use MPK in a store plug in and gap limit has to be set high. It is not good idea to take options away from wallet after users have adopted. I think developer is trying to make wallet more user friendly for newbies at cost of upsetting present users.

I acknowledge there is a bug with the current gap limit flag (-G) operation. I will fix it for the next release.

if you need to change the gap limit in a 1.9.x wallet, you may do it in the python console.

For example, to set it to 10, by type:


then close the electrum client, and restart it

Many thanks, I reset the gap limit as directed and I can use 1.9.4 now.

Looks like I wrote too soon. After I set the gap limit where I needed to, 1.9.4 worked for awhile then became non responsive, then starts synchronizing again. After a few minutes synchronizing stops, then shortly becomes nonresponsive again. As is I cannot use 1.9.4 portable, going back to 1.8.1 portable.

Many thanks !

  Please bring back the expert mode.

What's with the 0.0.0.0 entry in the server dialog? Probably just a bug (or a geeky way to tell electrum to go into offline mode)?

Electrum 1.9.5 was released. (binaries will follow)

Changes:
* coin control: the 'prioritize' command is replaced by a "send from" menu in the Qt GUI.
(you may select multiple addresses to spend from with the mouse, and the "!" shortcut is compatible with this)
* used addresses are moved to a collapsed section
* more bug fixes

  Thanks! Expert mode available?

And here's a screenshot of coin control (Win XP):

https://i.imgur.com/uciiQu1.png

Nice... will the addresses have labels too? (Cant test it since portable version isnt available.)

oh lord this goddamn electrum still doesnt connect. always get the red dot when opening.
Im still using the 1.8.1 which doesnt dissapoint like the newer versions

why did you implement these bugs electrum?
Do you want to make me anrgy?

I am planning to install Electrum 1.9.5 on Microsoft Windows OS using the "sources installation" method.

According to the instructions on electrum.org/download.html, I have to install PyQt4 first.

On PyQt4's page hosted by SourceForge, there are 6 files available:

PyQt4-4.10.3-gpl-Py3.3-Qt5.1.0-x64.exe

PyQt4-4.10.3-gpl-Py3.3-Qt5.1.0-x32.exe

PyQt4-4.10.3-gpl-Py3.3-Qt4.8.5-x64.exe

PyQt4-4.10.3-gpl-Py3.3-Qt4.8.5-x32.exe

PyQt4-4.10.3-gpl-Py2.7-Qt4.8.5-x64.exe

PyQt4-4.10.3-gpl-Py2.7-Qt4.8.5-x32.exe

Question #1: Which file should I download and install?

Next, the instructions on electrum.org/download.html state that one should install Electrum-1.9.5.zip

Question #2: How does one install it on a Microsoft Windows OS machine? I have unzipped Electrum-1.9.5.zip and there is no setup.exe.

Lastly, the instructions call for execute 'python electrum'

Question #3: Do I have to first open a command prompt? Some further instructions would be helpful.

Any helpful advice would be much appreciated.

This is what's happening to me with Multibit for months... and now (right when 1.9 was released) I was just moving to Electrum. LOL!
Anyway I am confident Elcetrum devs will solve the new issues, they seems more active and well-disposed.

Hi flatfly

Some more questions:

My Windows OS is 64-bit.
Question #4: Can I install PyQt4-4.10.3-gpl-Py2.7-Qt4.8.5-x64.exe instead of PyQt4-4.10.3-gpl-Py2.7-Qt4.8.5-x32.exe?

You stated that I just have to unzip Electrum-1.9.5.zip.
Question #5:  Into which directory or folder?

You mentioned that I have to install Python 2.7.6 first.
Question #6: Is it sufficient to just install Windows X86-64 MSI Installer (2.7.6) or do I have to install Windows X86-64 MSI program database (2.7.6) as well?

Suppose I have installed Python 2.7.6, PyQt4 and Electrum-1.9.5.zip. Next I open a command prompt as in the following:

C:\>

Next, I type execute 'python electrum' as in the following:

C:\>execute 'python electrum'

Question #7: Is the above step correct?

Hope this helps...

Is it possible to have both, prioritize(the default) and Send from?
Great app, btw. Thanks!

The OS X link still points to 1.9.4, though 1.9.5. can be downloaded if you manually change the URL to http://download.electrum.org/electrum-1.9.5.dmg

There is a wrong config in the 1.9.5 for OSX that doesn't let you connect in the first run. It only affects Mountain Lion and older, it is being reviewed.

I've just upgraded Electrum 1.9.5 on Ubuntu 13.10, and apparently nothing changes, I cannot see the new coin control "send from" and the network doesn't connect even if if uncheck autoconnect and select a server manually. I have tried to reload the wallet but nothing changes.

Maybe the linux version was not upgraded??

Anyone with this issue?

I don't think this is specific to OS X.

Also running on Ubuntu. I do have the coin control functions. You sure you upgraded correctly?

I think the upgrade was correct.

First, I closed the old electrum application then I executed from a terminal:

sudo pip install http://download.electrum.org/Electrum-1.9.5.tar.gz#md5=e8d66b08f7d1d745e1de04a090d199c2

Now when I open electrum I can read the versión 1.9.5 in the title bar but the new control functions don't appear.

Same on Win7, running 1.9.5 portable, no coin control, feeling dumb.

select one or several address in the receive tab, and right click

Oh, got it, that makes sense. Thank you for this excellent piece of software.

electrum why doesnt the auto connect work?
Only a red dot appears and no connection works out

Ok. Right clicking on one or several addresses on the receive tabs does the trick. Thank you for this improvement.

But what about the connecting issue?

Another bug:
If my laptop goes into sleep mode and starts up again, Electrum won't sync or reconnect.

No problem with my home laptop, it connects just after starting. I must check my work laptop.

Hi,

it seems that freeze/unfreeze resets the column width of "Address" every time. Using 1.9.5 standalone executable on Win7 x64.

While the idea of coin control is really awesome, I prefer the implementation of coin control is implemented for the stock client:

Cheers and thank you very much for this great client nevertheless! :)

Feel free to port it to Python and send a pull request. I'm sure it will be very welcome.

If I wanted to split the seed in two parts would this procedure make sense for split cold storage:

* Generate two normal seeds by starting Electrum without datadir (part1 and part2)
* concatenate the two parts with a single space in between
* use concatenated parts as input to "restore from seeds"
* put one part to a safe place (bank locker); keep the other one safe, too
* restore from concatenated parts whenever necessary

You can generate a new wallet using the -w switch. No need to move/rename the data dir. Run electrum --help for more details.

As far as splitting the seed goes you can also use shamir's secret sharing algo to create arbitrary n of m splits. Google shamir's secret sharing for more info. There's a ready made program out there called ssss

Thanks for the hint. I read about ssss but I like the nice pronounceable words from the Electrum seed better.

Yeah they definitely are more user friendly. ssss is for when you need more than the straight forward n of n split.

Electrum 1.9.5 portable isnt working portable. It doesnt find the wallet and creates a directory in the system dir which shouldnt happen for a portable version i guess.

What's the md5 of your 1.9.5 portable.

It shows the correct md5 from the download website. But i was wrong. The dir in roaming was old. It doesnt create it. Instead it creates a dir electrum_data in the rootdir of the .exe and then asks for creating a new wallet.

Should i push files into that dir somehow? I have the dir locale and the files blockchain_headers, electrum.dat and the .exe.

Ah yeah. The new file it's looking for is wallets/default_wallet. I believe there should however be a migration system in place that should automatically do this for you. If it hasn't try moving your wallet to that folder/ filename but please back it up first :)

so electrum you arre still not workingg when arre you going to conect?

Cant connect here! what do?

I tried it. But pushing the 2 files and the dir locales to electrum_data/wallets/default_wallet didnt work. I then put them one directory higher and it started. But it doesnt save any settings. I cant change language or the currency.

Is auto-connect connecting only via SSL when i set it that way? The ssl-dropdownbox is grayed out then too so i wonder if it honors that setting at all with autoconnect.

It should take the electrum.dat in ~/.electrum and turn it to /wallets/default_wallet in the first run of the new versions. So you have to place your electrum.dat in the older default folder that is the legacy ~/.electrum hidden folder.

You can also use the File >Open option to select the desire wallet file, and then use the File > Copy option.

Im not sure if i see what you mean. It sounds a bit like linux directories?

Lets say my portable electrum is at L:\Electrum and all files are in there:
blockchain_headers
electrum.dat
electrum-1.8.1-portable.exe
and dir: locale

I put electrum-1.9.5-portable.exe in there and start it.

The following dir-structure is built:

electrum_data
  certs
  wallets

When i put
blockchain_headers
electrum.dat
and dir: locale

into electrum_data and stat 1.9.5 then it starts and creates a file:
electrum_data\wallets\default_wallet (Its a file, no dir)

It puts some files from the electrum servers in certs.

electrum.dat seems to be gone. Instead there is a file config. Electrum itself has its settings set back to default.

When i restart 1.9.5 all settings i made in settings or plugins are gone again. So no safing of settings happens.

The dir structure is then:
electrum_data
  certs
    (files from electrum servers)
  locale
    (dirs with locales)
  wallets
    default_wallet (file)
  blockchain_headers (file)
  config (file)
electrum-1.9.5-portable.exe (file)

Im not sure but i think the saving of configurations might be the only problem now.

Those member having connectivity problems:

Since yesterday I was problem when no connection or by receiving message "Synchronizing..." while trying auto connecting.

By restarting client always help!

Of course that helps, but it's not how it should work.

ThomasV is pushing some fixes to the server code to avoid this problems.

Don't worry, after some more fixes, you and all Electrum users will have to struggle your heads to find a reason to come here and say hi :D

Why would I need a reason to say hi? Hi! See, that is a "hi" without a reason :D
Well, not really, because you made me say hi, but mark my words, I will say "hi" in this topic without a reason!

Is version 1.9 going to make it into debian 8 stable? Or is it stuck at 1.8?

Can't seem to get offline transactions to work.

I create the transaction in the online computer using a watch-only wallet made with the public master key, transfer the transaction input file to a USB key, connect it to my offline computer and load it into the real wallet there made from the seed. The window that pops up says the Status is unsigned and that the transaction is unrelated to my wallet. It also displays (correctly) the inputs and outputs. I click Sign and enter my password. but nothing seems to happen, it sends me back to the transaction window. I save the file to the USB key but its identical to the input file, the transaction wasn't signed.

I'm using electrum 1.9.5 portable on both computers

This should be fixed in git head

https://github.com/spesmilo/electrum/commit/1004fbd8f89523facae934f9ee5885a66663fac2

https://github.com/spesmilo/electrum/commit/8b4410d86a9868a12a35c81e7be01659628e63c5

When will version 1.9.6 portable come out? And will the save settings problem be fixed then?

I tried to make an offline tx using the 1.9.5 portable build with the on/offline wallet method. The deseed command (console) doesn't work!
Then I tried the recover the (watch only) wallet with the MPK method: Not possible to use a previously imported key, the imported address has disappeared.

Now I wonder: Is this only a portable build issue? Is the "deseed" command not working anymore?

After I installed 1.9.5 all my receive addresses changed. How do I get my original receive addresses back?

Also, was that bug fixed when sending coin it wouldn't send and come back with some weird error? I posted this a while ago and will dig up the old post if needed.

UPDATE: this is not a bug. Stupidity on my part. I never clicked on the little tick mark that opened up my old/used addresses.

version 1.9.6 is released.

Changes:
 - During wallet creation, does not write seed to disk until it is encrypted.
 - Shows a confirmation dialog if the transaction fee is higher than 1mBTC.
 - fixes for various bugs reported recently.

Linux packages for now. Binaries for Win and Mac will follow.

I see what you did there, haha. And hello! (I told you I would come back to say hi!)

 The "deseed" command still gives the message:  What does that mean in practice?

"deseed" is not available in the python console. it is only available in the terminal.

it improves security. previous versions used to write the unencrypted seed first.
however, there is no guarantee that the encrypted wallet will be written on the same disk sector.

--> How do I use the deseed command with a windows build?

Thanks.

Use the command line of course.

http://windows.microsoft.com/en-us/windows-vista/open-a-command-prompt-window

Bring up the command prompt and run

electrum --help

for more information.

 Sorry, but it doesn't work that way!
 It would be nice if ThomasV could give a hint on this.

in a terminal:

if you cannot use a terminal, use the 'restore' menu to create a watching only wallet

Terminal:
  electrum -w /electrum_data/wallets/default_wallet - starts the client!
  electrum -w /electrum_data/wallets/default_wallet deseed - nothing!

  It seems that the "deseed" command isn't working.

Note: The 1.7.4 build works fine (deseed!)

ThomasV, could you please have a quick look at this thread (its a bit old already, are you aware of this, is it fixed already or is it meant to be that way intentionally? What does the corresponding BIP say about it?)

Working in 1.9.6

1.9.6 mac fails to connect to network (red light in lower right) and nothing happens when network button or menu item is clicked/chosen. 1.9.4 works fine.

OS version? <-- could this be mandatory on any comment?

On my OSX 10.9 it took a first run of 1.9.6, quit, then second run to get network green.

It doesn't work with the portable build.

The download link for the Windows installer version seems to be broken.

1.9.6 seems to work except the language setting doesnt work.

I dont get the new design. I cant prioritize an address but i can chose send from for an address. But shortly after, probably after a redraw, the window with the addresses in send-tab is gone again. I fill the amount, target and so on but no window for the source address. I have to rightclick the sending address again.

What disturbs too is that the list of addresses seems to be redrawn even more often. So when i want to copy a detail from an address description i end up doing it more than once because everything was reset. The same goes when i want to change the size of columns. When i dont close and restart electrum fast then the setting is gone and reset.
When i check addresses to find a certain one its extremely annoying to have to scroll down again and again too.

I dont see why the whole list has to be rewritten all the time. If details change why not simply change the details?

I now will try to be fast enough being able to send from the address i want.

The 1.9.6 Standalone Executable file does not exists.

This has been an issue for me for a long time. It's quite annoying. A couple times I started looking at fixing it and doing a pull request but after exploring it seems to be more complicated than a simple fix. But one thing I was thinking is that if any address line is selected then the updated could be blocked, or less often. Right now it just becomes a real pain to do anything more than a quick glance at addresses. If you need to spend time checking some values or doing something then you are constantly having to re-scroll and re-open groups. A more comprehensive fix would update contents in some less destructive way than just reseting and refilling.

Is there a way to disable the Used address hiding ? If there isn't, could you please include an option in the preferences to remove it ? Thanks.
I personally really don't like it for simplicity's sake.

ive got the same problem, if you find a solution please tell meee :)

i have the same problem.

if you find the solution please tell meee :)

I have the same problem.

if you find the solution

please tell meee :)

1.9.6 has a bug. You cant chose more than one source address. Firstly... if you chose a second one then the first one is deleted. Secondly. If you take some time than the source addresses are deleted because of the all-deleting redraw... so at the moment the priorize feature would be better than the actual state.

Yes, I tried to download the Standalone 1.9.6 and the link does not work.

I found a bug in 1.9.6 : If you are disconnected from the net, when you open electrum and choose Restore from seed, you enter the seed, and after it says you are offline it still tries to connect to the server, and it hangs there doing nothing. In windows you can close the "connecting" window and Electrum pops up, but in linux there is no close button in gnome so it just hangs there. Thanks.

Electrum 1.9.6 does not work on Mac OSX 10.8.5

I had to revert to Electrum 1.9.4 which work fine.

Same here

https://download.electrum.org/electrum-1.9.6.exe ----> 404 Not Found

Now it's uploaded but it seems that md5 hashes not matching from the site and the downloaded file...

Why ?

version 1.9.7 is available (source code)
as usual, binaries will follow soon.

changes:
# Release 1.9.7
* Fix for offline signing
* Various bugfixes
* GUI usability improvements
* Coinbase Buyback plugin

Ah this a way to monetize the software? Good. Some money flowing to the devs for all their hard work is good.

no, it is not.
but I do have plans for that, to be announced soon.

  Is there a more detailed description of these changes?

Offline transactions had problems; this should be fixed. As far as I understand the Coinbase Buyback plugin let's you buy back coins you sent after a transactions. Please correct me if I'm wrong :)

1.9.7... when you delete a label of an address then its stored only temporarely when you have the label plugin enabled. The empty string isnt saved but the old string is restored.

Hi ThomasV,
 
I am EXTREMELY puzzled.... Does this mean that the MPK is enough for the software to derive the full seed from it? This sort-of makes offline transactions useless, as the MPK goes to the onlne PC where it could be vulnerable.

I just tried again on a fresh install. Yes, just pasting the MPK into the wrong box creates a fully working wallet, as the software is able to derive the private keys from the Master Private Key. 

I think the name  "Master PUBLIC Key" is EXTREMELY misleading, as the word "Public" makes me think it's harmless to bring it around (i.e. to the online PC)

Did I mix things up, or is this how it's supposed to work?

You mixed things up. The master public key cannot be used to derive the private keys. You probably have the seed in hex confused with the master public key. The MPK consists of 128 hexadecimal digits while the seed is made up of 32 hex digits.

I have now double checked by re-installing Electrum on a fresh XP VM, and I am pretty sure I can confirm the issue, unless I am really mixing things up.

Please follow my process...

I select to restore from seed but then I copy the MPK (128 hex chars), not the seed: https://i.imgur.com/FMOOCFX.png

I get a wallet with my BTCs, and it does not seem a watch-only wallet: http://imgur.com/nZHymGe

I send a payment and get "payment sent" http://imgur.com/MBndxHG

the transaction appears to be signed:

{
    "hex": "01000000013fca0752d65f3903f51a3e7f8b7abd01bdafd255343a261df4bbe230eb93435c00000 0008a47304402202cd08bf90ac63784afb2dcf4f6e97b3c8781d3831c1897d379423d8343f9537c 0220275d30b59d7609508f1a4466e6bc414549c93cd6cda84f1ad9796c8eeb4679b1014104a9999 add8b93702c671b3ebceeab3b5a69bcd60d984372de4d73848b73e13fe3d25d1d9e7ab76f5dd74f abcbe831b44bdf9d8c6e2029344b6f3ec6fd401c2269ffffffff0260182300000000001976a914c b7801827ada1c3e2e7726762eddada2de61c83e88ac20043600000000001976a9147d4977a484da 53b5573032ca6d580996f133a63a88ac00000000",
    "complete": true
}

and seems to have been accepted (even not yet visible on the blockchain) http://imgur.com/jMVqVRV

BTW, the same address shows two transactions I generated earlier today with the same mechanism.

Again, I am very puzzled.

I also checked on the offline PC with Tools-Master Public Key and I get a window "Master Pulic Key" with the same MPK I pasted in the online PC (8206 .... 3835)

EDIT: the transaction in now in the blockchain: http://blockexplorer.com/tx/476f440dea98b03d4c495676e2d169a69e9f5ae963955570ef6f78b45dd03a13#o0

If you select 'restore from seed' and enter any hexadecimal string, it will use it directly as your seed.
It works with any hex string, whether it is a master public key or not.

The wallet created that way is not the same as the original wallet, that produced the master public key.
There is no risk for your original wallet.

Additional note: of course, I do not recommend this method to create a wallet.
There is no guarantee that a user chose hexadecimal string has enough randomness.
