The Flirc Forums
As the beta releases progress and get improved old ones will be unavailable. As beta's are approaching being released to everyone they change into a release candidate (or "RC").
e.g. Beta 2 is newer than Beta 1 but RC 1 is newer than both Beta 2 and Beta 1
All the latest beta images have been pulled. The release candidate is now 1.0.5 stable, and the beta firmware is now labeled 2.0 (included in the 1.0.5 GUI)
