Focus for the development team over the last week has primarily been on resolving server and client crashes discovered during internal testing of 0.49. Rather than address the crashes with a potential hotfix after the update (given the impact of the associated central hive reset and the steps taken to address the more prevalent duplication and abuse methods) the choice was made to unlock the update from our regularly scheduled maintenance window of Wednesday and rapidly iterate upon experimental.
What does this mean for the average chernarusian survivor? We will be pushing rapid updates to experimental and iterating 0.49 until the build is in a state ready for stable branch. We believe this will only be a matter of a few days. When the build is ready for stable branch we will work with our game server partners to bring stable branch offline, and update steam.
