Subject Re: [DISCUSS] Bugs-only strictness for bugfix releases
Date Mon, 07 Apr 2014 12:45:22 GMT
Christopher,

Can you provide a delineation between bug fix and improvement? I've noticed
that you recategorized several issues, including ACCUMULO-2638 and
ACCUMULO-2639 and was wondering what your criteria was for such.

Is a bug-fix only something that has been reported by a user?

Mike
