Any chance you could add a new prefix for FIXED in each version whilst we are going through the betas to show the following:
Fixed in Beta 3
Fixed in Beta 4
etc etc etc
Not sayin change all the current ones as I should imagine that would be a royal pain in the backside, however would help when looking through the bugfixes if when I find a bug, if Im running Beta 4 (for example) and on that bug it says "Fixed in Beta 3" I know to report that again as still having a problem. Whereas if it says Fixed in Beta 5, I know the bug is there and the fix will be applied in the next beta.
