2008/07/18 Here is a new release of fail2ban. 0.8.3 should fix the famous "Unknown error 514" and the wrong PID in fail2ban.pid. There are a few more fixes and improvements. I have not yet applied all the patches I received. This will be done in a next release.
2008/07/17 I will release 0.8.3 soon but Sourceforge.net seems to be migrating their services. I have some issues with their subversion repositories at the moment.
2008/03/01 Most of you have probably seen Fail2ban taking a lot of CPU and disk access on February 29th. We already fixed it and I will release 0.8.2 (which has nice new features) as soon as possible but in the meanwhile, please patch Fail2ban yourself. You will find a patch here. It's Python so no need to compile anything.
