Bitcoin version 0.5.2 is now available for download at:
  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.5.2/ (http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.5.2/)

This is a bugfix-only release based on 0.5.1.

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

Stable source code is hosted at Gitorious:
  http://gitorious.org/bitcoin/bitcoind-stable/archive-tarball/v0.5.2#.tar.gz

BUG FIXES

• Check all transactions in blocks after the last checkpoint (0.5.0 and 0.5.1 skipped checking ECDSA signatures during initial blockchain download).
• Cease locking memory used by non-sensitive information (this caused a huge performance hit on some platforms, especially noticable during initial blockchain download; this was
  not a security vulnerability).
• Fixed some address-handling deadlocks (client freezes).
• No longer accept inbound connections over the internet when Bitcoin is being used with Tor (identity leak).
• Re-enable SSL support for the JSON-RPC interface (it was unintentionally disabled for the 0.5.0 and 0.5.1 release Linux binaries).
• Use the correct base transaction fee of 0.0005 BTC for accepting transactions into mined blocks (since 0.4.0, it was incorrectly accepting 0.0001 BTC which was only meant to be relayed).
• Don't show "IP" for transactions which are not necessarily IP transactions.
• Add new DNS seeds (maintained by Pieter Wuille and Luke Dashjr).

Great job! Well done! Is this the same as the rc1 that you posted earlier (Except for the version number change of course) or has something been changed between this release and rc1? Thanks :)

minimize bug (https://bitcointalk.org/index.php?topic=58450.msg699859#msg699859) reported on the release-candidate thread...

No PGP signatures?

No changes, but the Windows Bitcoin-Qt was rebuilt by multiple people (devrandom and sipa) to ensure integrity since it isn't 100% deterministic yet.

Please report to the GitHub issue tracker now.

I presume more to follow shortly. Gitian sigs at https://github.com/bitcoin/gitian.sigs/tree/master/0.5.2

Which git repository is the v0.5.2 tag in?  I've not been able to find it.

Thanks.

git://gitorious.org/+bitcoin-stable-developers/bitcoin/bitcoind-stable.git worked for me.

updated to 0.5.2-beta
Thanks!

I installed this version and it worked just fine initially.  But now every time I try to run it I get a DEP violation.  Does this version of the official client really execute code from the stack or other protected data only memory areas?!?!?!?!?
Thanks,
Sam

I'm assuming "DEP violation" is some kind of no-execute thing? AFAIK, no Bitcoin-Qt does this. Since you mention it worked before, I would be concerned that perhaps you've been infected by some kind of virus/trojan. I suggest getting your wallet.dat off that computer ASAP just in case, then looking into it further.

Yes DEP is Data Execution Prevention.  Memory can be marked as Data only so that it should be impossible to execute code from an area marked as such.  The stack is the main area that should be read only but many old/legacy apps do execute code from the stack.

I appreciate the assurance that the Bitcoin Client does/should NOT do this, which is what I had suspected and hoped for.

I am currently scanning my system for virus's/malware.  I don't think I've gotten anything on this machine, but hey it is Windoze.
Thanks,
Sam

Well I have scanned this system with Security Essentials, MRT, System Sweeper and Windows Defender Offline.

So I don't think it has a virus.

But now after several reboots I can again run the client.  Doesn't exactly give me a warm fuzzy feeling.

By the way, why is it now called Bitcoin-qt?
Sam

Try MalwareBytes.

It is called Bitcoin-qt because the GUI interface was re-written in the QT language by Wumpus.

Perhaps open an issue on GitHub; maybe someone else knows how to debug Windows stuff.

The old client (aka wxBitcoin) was replaced with Bitcoin-Qt, which is a complete rewrite of the GUI.

I just scanned again with Malwarebytes.  The only malware it found was CGminer and Ufasoft miner.
Thanks,
Sam

If I can get it to reproduce I'll do that.
Thanks,
Sam

Would it be possible to have a forum topic just for release announcements for the Bitcoin Client software?  It would be nice to have them all in one place.
Just a thought,
Sam

what windows version are you running? i'll see if i can reproduce it.

edit: tested on windows xp sp3, in VMware, no DEP issues.

Yep, using WinXP Pro SP3 as well.  I had rebooted several times running virus scans and chkdsk and now it seems to be running fine.  I just thought it was strange that I was getting DEP violations out of the blue.  Maybe Windoze just got tired and needed rebooting.  That happens sometimes.

If I can reproduce it I'll open a bug.  Sounds like nobody else is having this issue, so that's good.
Thanks,
Sam
