Barring any last-minute showstopper issues, the plan is for release candidate 5 to become the official 0.6.0 release on Wednesday. @p{par}

So please help look for last-minute showstopper issues: @p{brk}
  @s{(link)} @p{par}

The major changes from release candidate 4: @p{par}


@p{(li}Much faster writing of blkindex.dat during initial blockchain download (by modifying the default bdb environment cache settings)@p{li)}

@p{(li}A new policy for wallet.dat upgrades: use the old format unless the user either uses a feature that requires an upgrade (encrypts the wallet) or explicitly requests that the wallet be upgraded using the new -upgradewallet option. New wallets will use new features (for 0.6, the only new wallet feature is compressed public keys).@p{li)}

@p{(li}bugfix introduced in rc4 for an assertion failure that could occur during blockchain reorganizations@p{li)}

@p{(li}New code for managing the addr.dat file that prevents an attacker from filling it with bogus entries. @p{brk}
