Hi,
0.12.1 has been released, mainly fixing a nasty performance problem in
match_all queries with combined with negative queries. But, the good news is
that those should be faster now, even compared to 0.11 (the bug was
introduced because of a performance optimization I did for match_all
queries).
Other bug fixes from master have been backported, like geo distance filter
parsing, thrift, and more. All listed in the closed issues section under the
0.12.1 tag.
This release is a recommended upgrade to all users, and allows for rolling
upgrade with a 0.12 version (no protocol changes).
