4月20日 - YORISYAN
FROM: High Command
TO: Arma 3 Users
INFO: 1.58 Release Week, Campaign Unification, Action Filtering, Eden Editor Updates, Targeting Improvements
PRECEDENCE: Flash

SITUATION
This week we want to finally release 1.58 to every player. Besides several fixes, the last addition we sought to get in was merged on Friday (action filtering for weapon switching). That gives us all a day or two of further Release Candidate testing[dev.arma3.com]. Take a look at the pseudo change log[forums.bistudio.com] on our forums for the highlights of this update. If you're aware of critical issues remaining in the build, alert us[forums.bistudio.com] via the forums please. Catch you on the flip side!
