A couple of rather vital balancing issues and bug fixes applied in this release. Also included is a new weapon (Flamethrower) and two new armor pieces. A larger update is planned in the near future with more game content, but there was however a need to release this fix asap. :)
A full update log is available here (.pdf) and the LBKR clients can be downloaded from the "Downloads" tab.
//Edit
Oops, I failed to update the files in the Downloads tab here on IndieDB, sorry about that! It's sorted out now though! =)
