RELEASE NOTES

# Release 1.9.8

(This release includes features initially planned for version 2.0)

* Electrum servers were upgraded to version 0.9. The new server stores
   a Patrica tree of all UTXOs, an idea proposed by Alan Reiner in the
   bitcointalk forum. This property allows the client to directly
   request the balance of any address. The new commands are:
      1. getaddressbalance <address>
      2. getaddressunspent <address>
      3. getutxoaddress <txid> <pos>

* Command-line commands that require a connection to the network spawn
   a daemon, that remains connected and handles subsequent
   commands. The daemon terminates itself if it remains unused for more
   than one minute. The purpose of this is to make scripting more
   efficient. For example, a bash script using many electrum commands
   will open only one connection.

edit: encrypt/decrypt methods were removed due to a bug

Great! The encrypt/decrypt functions seems to be really useful for services like https://www.b1txr.com or to be able to share Labels for recipients ala "public notes" of Blockchain.info but with more privacy.

[ThomasV]

Note: according to gmaxwell, the implementtion of these encrypt/decrypt is not secure.
I will try to fix them asap.

Thank you gmaxwell!

Hey, great work! However, the install still says 1.9.7!

I've just added the Windows and OS X binaries. They should be on the website tomorrow, as soon as Thomas is able to add it there.

For users on OS X.

I had trouble, again, building the OS X binaries. Please let me know if they don't work for you, and if so on which version of OS X you are running it.

[davout]

Nice !

[gmaxwell]

FWIW, for those curious— the thread on the encryption issues: http://sourceforge.net/p/bitcoin/mailman/message/32107008/   (I made several posts after the first one too)

The new commands are:
      1. getaddressbalance <address>
      2. getaddressunspent <address>
      3. getutxoaddress <txid> <pos>

Just to be sure: getutxoaddress does not work with multi signature outputs, right?

Just to be sure: getutxoaddress does not work with multi signature outputs, right?

I believe it should work - there was a fix applied to servers especially for this. There may be some older v0.9 servers which run an old version of the database (v2) where it doesn't work. Can you test this with electrum.no-ip.org for example? This is an up2date server. If it works, can you please point out the servers which don't yet work?

yes, it works, but you have to use an updated server.
here is the result with electrum.no-ip.org

Code:

getutxoaddress 6b01861beb0a8e510214650b416af311f8d55b1bae3e83d02dca8578b44288ed 0
{
    "address": "34yB9GTp3yAzQRuyKRdVYV3AXrBFPsYDN7"
}

[dexX7]

Hm. Maybe I'm doing it wrong? All multi signature outputs I tested - redeemed or not redeemed - return null.

I connected to electrum.no-ip.org:50001.

How are OSX users finding it? Stable?

How are OSX users finding it? Stable?

No problems found on Mavericks or Mountain Lion so far. Report any issue, please.

[RoxxR]

Daemon mode is broken under Windows.  Os.fork() cannot be used as it is not platform independent - it's a Linux-only function AFAIK.

[ThomasV]

Hm. Maybe I'm doing it wrong? All multi signature outputs I tested - redeemed or not redeemed - return null.

The multisig scripts outputs you tested are not P2SH addresses.
see for example https://blockchain.info/tx/186b4abdca8cf3edcaee8b56c28be9bb481ea1d7ed62903595661118d6d548b3
this is a multisig script, but not p2sh.

A p2sh address corresponds to a script of the type OP_HASH160 <hash> OP_EQUAL

IIRC other script types are not propagated by the network, you must be a miner to include them to the chain.

Great to see the new version. Mo problem with it on Mavericks OS. Would telll you if it goes bad

[dexX7]

IIRC other script types are not propagated by the network, you must be a miner to include them to the chain.

The multisig transactions I mentioned are standard transactions. So to redefine: getutxoaddress does not work with multisig transactions but with P2SH multisig.

Anyway, great job. I love Electrum!

Electrum is an outstanding Bitcoin client. Thank you for creating it.
I am a retired programmer (C, C++, Java, PHP) and have been away from programming for over 5 years.
After using Electrum, I have been motivated to learn Python, and I am most impressed with the language.
Thanks again for your outstanding creation.

non-P2SH multisig txs won't be standards anymore
