Bitcoin-Qt version 0.8.5 is now available from:
  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.5/

This is a maintenance release to fix a critical bug (https://bitcointalk.org/index.php?topic=290922.0);
we urge all users to upgrade.

Please report bugs using the issue tracker at github:
  https://github.com/bitcoin/bitcoin/issues


How to Upgrade
--------------

If you are running an older version, shut it down. Wait
until it has completely shut down (which might take a few minutes for older
versions), then run the installer (on Windows) or just copy over
/Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

If you are upgrading from version 0.7.2 or earlier, the first time you
run 0.8.5 your blockchain files will be re-indexed, which will take
anywhere from 30 minutes to several hours, depending on the speed of
your machine.

0.8.5 Release notes
===================

Bugs fixed
----------

Transactions with version numbers larger than 0x7fffffff were
incorrectly being relayed and included in blocks.

Blocks containing transactions with version numbers larger
than 0x7fffffff caused the code that checks for LevelDB database
inconsistencies at startup to erroneously report database
corruption and suggest that you reindex your database.

This release also contains a non-critical fix to the code that
enforces BIP 34 (block height in the coinbase transaction).

--

Thanks to Gregory Maxwell and Pieter Wuille for quickly
identifying and fixing the transaction version number bug.

Working on Win7x64. Thanks guys!

Stupid question... but is this supposed to also be available on bitcoin.org? If not, does that mean this is a testing only release?

It's on Bitcoin.org.

In less than a week another update! thanks for this critical job.

What a relief. Thanks for staying on top of things. I was having this issue myself and was hesitant to re-index the database. Glad I didn't go through with it.

Thanks a bunch Gavin!

Long live our sovereign currency!

Shouldn't this thread be stickied instead of the 0.8.4 one?

How do i update on ubuntu?

My Bitcoin QT client has just "crashed" again. I used it this morning without any problems, went to open it up just now and it said something like "couldn't index the blocks" and "would I like to re-index the blockchain" just like it did earlier in the week when the bug originally surfaced.

Might I have done something wrong or is there another bug?

This report is a bit vague...

Was this on 0.8.5 (released less than 72 hours ago) or the previous version which didn't have the bugfix?

I was just about to upgrade but then I saw your post & panicked :(

---

Edited to add:


Same here...

Reindex seems to be going normally. has finished, and bitcoin-qt is now running normally.

@bitcoinchecker: I don't think your crash is happening for everyone / I wasn't able to reproduce during upgrade from 0.8.4 to 0.8.5

Yes, it's still the old version for some reason.

I must have downloaded the updated wrongly.

But how come everything was working ok this morning?

Hello, i am using win7 32 the qt is running fine, i upgrade from 0.8.3 to 0.8.4 and now to 0.8.5 and no need to reindex the blockchain. Congrats

When the PPA ver will be added?  ???

Windows 8 64-bit working fine

Thanks for the quick release with the bug fix.  The new version is working fine for me.  Much appreciated.

Just got this message with Qt: "Corrupted Blockchain Detected do you want to rebuild".  Advice please.  TIA

Me too.  0.8.5 Mac bitcoin-qt release on OS X 10.8.4

My Mac LevelDB corruption issue report updated:

https://github.com/bitcoin/bitcoin/issues/2770#issuecomment-24437169

Interesting.  Installed the update and currently re-indexing; fingers crossed that will be the end of this issue. I'm on a PC running WB 7. According to other info I've received I should have never started re-indexing when the problem first occurred and just installed the 0.8.5 fix.  Unfortunately, I did not learn of the fix until too late.  Thanks for responding and hope all goes well for you.

I've been updating each time, yesterday to 8.5, which appeared to work fine

Just restarted my machine (Due to a bloody forced windows update!) and bitcoin-qt stated the block chain was corrupt and needed re-indexing.

Doesn't seem right :/

I am not sure how I can tell what version is  being offered via the PPA.....
I am using Ubuntu 12.04 LTS, via the PPA. I got a 'corrupted database' error when starting up yesterday, which I thought was strange. I keep backups, and I restored the previous day's data but still got a problem running bitcoin qt. I then restored  the data from a week ago, still problems. I ended up accepting a re index, and it seems ok  now in the morning. I was getting curious as to why the backup  data still apparently gave problems, but if a bug was the cause, then that explains it. I guess (??) tat the PPA has given me an update by now? The debug window states that the version is
satoshi v 0.8.4.0-g839c7d1-beta

Now that I have upgraded to version 0.8.5, do I still need the "checklevel=2" line in my bitcoin.conf file?
Is it now safe to comment out or remove this line, or was its inclusion intended to be permanent?

You may remove checklevel=2 from your configuration.

I feel bad for all those that now have to wait days for their machine to catch up to the block chain.  :-X

Yeah, i wonder why that is still not "fixed".

What is the default check level and check blocks for version 0.8.5 ? Is it the same as before? (which is? 3 / 288?)

Yes. I guess that the release notes would say something if this stuff was changed. In any case I restarted my daemon yesterday and these were the numbers used.

Yeah. This really sucks. Updated to 8.5 and now having to reindex.

i don't know how to check what's the version of my Bitcoin-Qt (it's used for mac)

When you first start it up you should see a box which says  "v0.8.5-beta"

When it is open (like in your screenshot above) you can check by clicking  "Help > About Bitcoin" and again it should say "v0.8.5-beta"

good work

if you installed by adding the PPA then just do a sudo apt-get update and a sudo apt-get upgrade and it will update the bitcoin-qt...

I download this but crushing again and again every time when I want to login its need to redwonload what is wrong with this

Well reindex doesn't solve anything, start the client with bitcoin-qt --args -checklevel=2

That will let you use it, or add the checklevel=2 in the .conf

reverted to old version after

i have db5.1 installed, but dont care about wallet anything on this server

Thank you for this!

i will update now。

So I upgraded both my main OS (OSX 10.9) and Ubuntu running on a virtual machine to 0.8.5 and downloaded bootstrap.dat torrent to import into the programs.

I went to do this on OSX first, the process took approx 3 days, which I thought nothing of, as my download for the same blockchain through the client will probably take longer than this. However, I just started importing bootstrap.dat into Bitcoin-Qt 0.8.5 in my Ubuntu VM, and it has done over 50% in less than 20 minutes!?

Anybody else experience anything like this? Anyone have any ideas about how/why this might happen?

I have a late 2012 iMac with 16GB ram and an i7 3770k (21.5"), if that will make any difference to anything... Also, if you didn't catch my OS is Mavericks (developer preview 8 I think), but sure I did the bootstrapping procedure with the previous torrent (~7GB, the one now is ~9.3GB) and it took just as long, but might be mistaken about that...

Ever since I upgraded to 0.8.5 it periodically gives me an error complaining about the computer's time being off. In Windows 7 x64.

I keep the time sync'd through the internet, & even went to task manager & increased the sync interval from 1 week to daily & it still happens every 2 weeks or so.

I disabled the clock sync with my Blackberry too so there wouldn't be 2 time sources.

The BIOS battery is only 2 years old & shouldn't be dead yet.

And it didn't happen until I upgraded to this version.

All I have to do is shut it down & restart the client, but it's a problem nevertheless.

I hope it's fixed in 0.9.0.

I was having a strange problem with a brand new PC box where the bios battery would go dead in days.  I would try putting in a new battery and see if that helps.  Good luck.

I have also had a weird thing where my clock was ~30 mins off. I don't know if it is related to bitcoin though. Bitcoin doesn't have access to set the system time I'm assuming.

If your CMOS battery, (usually CR2032) is not branded, I don't expect it to live more than 2 years. It's cheap enough to replace it and note the date somewhere (like a piece of paper taped to the side of the motherboard.)

Take note also, because sometimes instead of CR2032, you will find CR2016 which is thinner and has a shorter lifespan.

updated to 0.8.5-beta
Thanks for fixing that critical bug!

Could you guys please stop releasing a new version every 3 days?
Soon there will be a new version before one had the chance to sync the old one.

yes its creating confusions many just trying to fix old one and as its set there is news that new version is ready its not a fair policy you must think about this  :)

How many ram memory do I need to run this properly on linux? In case I don't have enough ram, is swap sufficient? Possibly how much ram combined with swap do I need at least?

Thanx i update my walet brother for news this

Request: publish checksums of official builds to at least one, and preferably several, webpages authenticated by HTTPS.

A thread like this would count as one. The plain-HTTP sf.net files area does not.

The PGP-signed SHA256SUMS.asc is the right idea but requires extra steps to check.

Good idea. I nominate you to be the Official Checksum Publishing Person.

Bitcoin-QT can be used as portable. But it communicates to much with usb stick. And it works very very slow. Is there any development works for that?

Hello Gavin Andresen. I would like to put an idea forward for the QT client.

A little bit of an update to wallets and layout.

Instead of having 1 total balance for all of your address to have next to each address a small box with amount of coin that address has in it and have the total as is.

This would be a nice little feature so you know how much coin is in each address. Hope to see this in your client.

If you use the Coin Control patch you'll be able to not only see what balance is in each address (with even repeated addresses due to receiving more than one payment there) but also pick which entries you'd like to use to make new payments.

Where do I get that from?

Just installed it on another PC of mine... consistent database corruption errors.

Brutal!

This is inherent in storing the entire blockchain. USB sticks are notoriously slow with this workload. I suggest using a lightweight client if you need it to be portable.

What will be supported is storing the blockchain in a different place as the wallet. So if you just need the wallet to be portable, that would be useful I guess.

I'm synchronizing with network. It's really boring, but I must do it.

If you want to use the Bitcoin-Qt client you have to. It's the most secure wallet. If you don't want to download the chain then you can use another client like Electrum and or Armory.
Or an online wallet but I don't recommend using those. I recenty had to re-index the chain -.-  It was the second time I ever had to do this since I initially downloaded the client a few months ago.
Yes it takes a long while depending on your computers capability but in the end if you take the correct measures you can rest assured that you're using one of the most secure wallets.
I mean, look what's happening to Inputs.io right now, and it claims ultimate security.

I am already 3 days busy with synchronising the network while normally it took one day. What is wrong?

config still fails at this, have to manually edit it

I was seeing in db.log too as well as using the latest version from github with libdb5.1.
Removing wallet.dat didn't help.
Changing to libdb4.8 fixed the issue. You can find them in the PPA if you're using ubuntu.

when i installed the latest version, did it make my old unecrypted backup obsolete? or if someone got a hold of it they can still manipulate it unecrypted?

Still busy, already 5 days now..what could be wrong?

Connected to some crap peers?

opted to go with multibit after bitcoin-qt simply would not grab non-corrupted database files.  over... .and over.... and over again.  multibit is great.  :)

I just checked the current Bitcoin Client v. 0.8.5 for viruses and got a hit:

VirusTotal Report for bitcoin-0.8.5-win32-setup.exe

https://www.virustotal.com/de/file/6f6b8fd68f56a8e700090267c53aa592b9c9e5c993f44c7be11ba9b87e1f92bb/analysis/1382185873 (https://www.virustotal.com/de/file/6f6b8fd68f56a8e700090267c53aa592b9c9e5c993f44c7be11ba9b87e1f92bb/analysis/1382185873)/

AhnLab-V3 Trojan/Win32.BitCoinMiner

It is probably a good idea to contact the Ahnlab Antivirus to verify and remove the false positive,
as this makes a bad impression for anyone checking the official Bitcoin Client with Virustotal.

Ahnlab is the market leader in AV-technology in South Korea,
so this is should really be an issue for asian Bitcoin users.  :-\

Hmm, that is why my client is STILL synchronizing with network for already 7 days?

Most likely not. I was just pointing out the problem with a false positive. This does not mean that there is a technical problem with the Bitcoin client. But there is a psychological problem if it shows up as a virus in even just one of the scan engines at Virustotal, of course.

bueller?

I have one question I am new for Bitcoin Qt and just download this and install its running for 7 days and just reach to 56 weeks behind how much time still need to reach for current day and can I my bitcoin received address add to Electrum because my bad I give to someone and have payment which I need right now but its taking too much time  :(

But when it's complete you'll rest assured knowing that your bitcoins are safe.

Why bother? They will release a new version by then anyway.
And soon you will need an ASIC to keep up. ;)

Export your private keys and import them into multibit.

7 days?  Jezus, you want to be complaining about your ISP before the blockchain dude;  I did a fresh install last night in what can't have been more than 8 hours, probably a lot less, I wasn't paying close attention.

I have also trouble like this can you tell how can I Export my private keys and import them in multibit please send in pm or post here

When will come the next version ? it will be 0.8.6 or 0.9.0 ?

hope it could be 0.9.0 its good idea for bitcoin  ;D

The plan is to release 0.8.6 some time this week, and 0.9.0 in January.

Hello guys I have a couple of questions about Bitcoin-QT. When I originally installed the program I did not encrypt the wallet. I bought some bitcoin (small amount) and received it using the "generate address button". My question is now that I have encrypt it can I still use the button to generate a address or do I have to use the original one I created. Also if some one sends me bitcoin to my encrypted wallet will it need the passphrase to accept or will it just accept automatically like the first time (after the confirmations)?....one last questions will there be any fees charged to me if I receive like 5+ bitcoins?

You can still receive coins automatically without any extra work.

You can use your original address or generate another one (I use different addresses depending on why I received the money)

You will need to supply your wallet passphrase when you send coins

Fees are paid by the sender, not the receiver.

Who decides on the numbers? why 0.8.5 ?

I read somewhere that synchronizing the blockchain would go faster in this release.
It however still takes a lot of time, even after already having downloaded and imported the 9GB torrent file discussed here: https://bitcointalk.org/index.php?topic=145386.0

bitcoin-qt 0.8.5 on my mac book pro crashes EVERYTIME I open it. I have to rebuild the data base whenever I want to use the program.

I've tried the "checklevel=2" fix and it doesnt work.

rebuilding the DB takes several hours and the computer runs REALLY hot while its doing it.

Try using one of the test builds that have been made in an attempt to fix this:
https://bitcointalk.org/index.php?topic=337294.msg3718821#msg3718821

Tried them, both crash with the same corrupt database error. I cant re-index right now because I dont have my power adapter. I'll do it tomorrow and retry

Posted my results into that thread. Thanks for the pointer!

I'm not sure if this is the right spot for this post but I've been wondering for a while.  The first and only client I downloaded and continue to use is 0.8.1-beta.  I see that sometimes people don't have to pay for transactions, how do they do that? do I need an updated client?

I also notice that sometimes it says I have to pay a transaction fee of (for instance .0005) and then I confirm I still want to send and it ends up taking less for the transaction fee.  Can anyone advise? thanks

Warning dont use untill confirmed
Is this legit ?
http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.6/test/


or a scam ? someone posted it on reddit..

to the dev's that are subbed to this thread.

Looks like my problem had something to do with permissions within my bitcoin-qt folder. I needed to take over the chainstate folder and one other folder.

I wish I knew the exact commands that helped me but I've closed the IRC chat client.

Bitcoin-QT now launches normally after power cycles and normal shut downs and restarts of the app.

Thanks again for the help!
