Current 0.4.4.7 testing branch runs pretty stable for now. This branch is available here for public testing:

https://github.com/novacoin-project/novacoin/tree/current

Basic list of changes:

1) Pruned transactions serialization support.

Pruned transaction records are now saved into coinsDB. These records are composed of 13-14 bytes of metadata (block height, coinbase/coinstake flags, block and transaction timestamp). This resolves all syncronization issues. Though currently there is no lifetime limit for such records, cleanup for old records will be implemented in the future versions of NVC client (this cleanup will be performed after reaching the 520-blocks maturity window, I guess).

2) Conflicted transactions handling.

Stratum server update:

• Switch to regular addresses instead of public keys;
• Merge all changes from the latest snapshot of upstream.

Recent Novacoin commits:

https://github.com/novacoin-project/novacoin

• -confchange option added. This setting allows user to prevent an unconfirmed change from being spent, disabled by default;
• -enforcecanonical option added. This setting enforces canonical PUSH operators for unconfirmed transactions, enabled by default.

To caclulate need to change PoS difficulty and amount

Public test nodes started.

-o stratum+tcp://p2pool.novaco.in:8778 -u <your address> -p <anything>
or
-o stratum+tcp://85.234.62.99:8778 -u <address> -p password

Another front-end for local node.

P2Pool was updated to 13.4-25. It’s recommended to apply this update because it fixes an issue with block header timestamp. This issue could cause generation of invalid blocks.

Please note that it uses a new share chain and has no relation with 11.4 version.

Network info:

• PPLNS rewards system, N=4320;
• 15 seconds shares target spacing;
• Working stratum support;
• ~20-30% lower share size.

Also there are no raw public keys anymore, regular wallet addresses are used instead.
