For Ubuntu users, there is a new ppa maintained by Matt Corallo which you can add to your system so that it will automatically keep bitcoin up-to-date. Just type
sudo apt-add-repository ppa:bitcoin/bitcoin
in your terminal, then install the bitcoin-qt package.
BUG FIXES
-
Re-enable SSL support for the JSON-RPC interface (it was unintentionally disabled for the 0.5.0 release binaries).
-
The code that finds peers via “dns seeds” no longer stops bitcoin startup if one of the dns seed machines is down.
-
Tooltips on the transaction list view were rendering incorrectly (as black boxes or with a transparent background).
-
Prevent a denial-of-service attack involving flooding a bitcoin node with orphan blocks.
-
The wallet passphrase dialog now warns you if the caps lock key was pressed.
-
Improved searching in addresses and labels in bitcoin-qt.
