X-Git-Tag: svn/VALGRIND_3_1_0~494
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=477d989b983868d46dadf677c2ed32e5f32523d3;p=thirdparty%2Fvalgrind.git

Completely restructured this file (don't bother trying to read the
diff).

It's now laid out according to which release(s) a bug is targeted for,
ie.  which release(s) we want to fix it by.  Eg. 3.0.1 and 3.1.0, or
3.1.0 only.  This is more useful than grouping the bugs by when they
were reported.
