The version field in Bugzilla stops at 0.28.x. It’d be great, if they could be extended, or if unneeded, be removed.
I'm not sure who can make the required adjustments to bugzilla. Anyway, it's always best to check if the problem is reproducible with the current pixman git master. And you can also mention the affected pixman versions in the text of the bugreport in the case if it is desirable to have the fix also backported to some old stable release.
I have added the newer version numbers. Siarhei, if you want bugzilla admin privileges, I'm sure the fd.o admins will give them to you.
