Coin Control merged into 0.4.4.5, testing build for win32 is available:

New p2pool release is planned for this weekend. It will start an independent shares chain due to some incompatible changes.

• Fee for coinbase isn’t required since 20 Sep 2013, so this code will be removed;
• ECDSA signature isn’t required for PoW blocks since 20 Sep 2013. This allows us to remove a few serious limitations, such as requirements for public node fee and wallet unlocking;
• -a option support, wallet address as worker name support;
• No truncation for rewards lower than 0.01 coin;
• 15s shares target spacing.

Successfully ported to ARM, so now you can build novacoind & novacoin-qt for Linux/ARM just like you do it for Linux on x86 platforms.

Windows 64-bit build is updated.

• Slightly lower memory consumption;
• No LevelDB abstraction object recreation during the checkpoints handling;
• ~ 10% faster block index object initialization.

Experimental native build for 64-bit Windows is available.

Make backup of your data folder before trying this build. Reports are welcome.

Tested for a few hours… It seems that this build is stable enough.

Installer for current release:
http://sourceforge.net/projects/novacoin/files/novacoin-setup-win32-amd64-0.4.4.4.exe/download

Minor client update is available.

v0.4.4.4

• Google’s LevelDB support is implemented, and used as transaction storage by default*;
• The -nosynccheckpoints option is replaced with the new -cppolicy=mode option**;
• RPC: blocktrust and chaintrust fields added into block dump function;
• Many minor fixes and optimizations.

Currently we are working on LevelDB support, source tree will be updated soon. Testing snapshot is quite unstable, but syncronizes well enough.

LevelDB minimizes memory usage and makes syncronization faster, but there is also some Proof-of-Stake related side effects. E.g. validation of PoS block requires additional LevelDB transactions. As the result, performance benefits are lower than it would be for pure PoW based system.

Experimental Win32 build with LevelDB storage:

Reports are welcome.

If you wish to make your own build then you need “USE_LEVELDB=1” option.

UPDATE: merged into the main tree. Testers are welcome.
UPDATE2: memory leak found, thanks for the report
