[vbox-dev] About versioning and release

[유재용]

Hello VBox,
I would like to bisect between two versions (4.2.20 and 4.2.22) for finding a commit that arises a bug.
(GfxBench in Windows8 does not work in 4.2.22 but works fine in 4.2.20).
So, I downloaded the svn repo but I'm failing to find a svn revision that matches to 4.2.20.
I thought it is around r49681 because it is the similar date to 4.2.20 release date, but it looks like there is a huge difference of guest driver between
the downloaded tarball of 4.2.20 and r49681.

Is there a way to figure out what is the svn revision ID of 4.2.20?

Thanks
Jaeyong
