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; this was not a security vulnerability).

  • Cease locking memory used by non-sensitive information (this caused a huge performance hit on some platforms, especially noticable during initial blockchain download).

  • 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).
