I'd suggest simply changing your version numbering (Currently you're using A.B.C)
Quite apart from the issue of A=0 (see [1] below), either incrementing the 'B' for features or splitting the 'C' into 'C.D' and differentiating the feature change releases from any bug-fix releases would allow users to estimate & judge the chance of issues in any particular release.
