This is a beta release for 184.108.40.20671
The purpose of this release is to allow users to get early access to fixes and provide feedback as it would be impossible for our internal team to cover due to the huge amount of different possible PC environments out there. We do recommend you use a new database as a precaution.
Even though we rarely see anything that serious in these betas, and they have gone through some internal testing, they have not completed all our internal tests yet and the chances of a bug are higher than normal.
You can manually download the build here, if you have any issues you can rollback to the last official version here.
Note: Restart of HM2 required after the installation before HUD will work on fast forward tables
