There's just some search fixes in this release. Important, but not especially interesting.
From the CHANGELOG:
* Several search fixes:
- With postgres search:
* Fixed reindexing after it broke with the previous update that eliminated
a lot of unneeded extra rows in the database.
* Fixed basic queries with NOT statements.
* Separately, fixed using NOT with subqueries. On a somewhat complicated
note, but in a way that appears to match standard Solr behavior, when
doing a query like "name:chef* AND NOT (admin:true OR admin:bleh)" it
works as is, but when a negated subquery is followed by another basic
query statement, it needs to have extra parentheses around the NOT +
subquery, like "name:chef* AND (NOT (admin:true OR admin:bleh)) AND
public_key:*". A convoluted and unlikely scenario, but it could happen.
- With in-memory search:
* NOT + subqueries was also broken with the in-mem search. The fixes for
the pg-search partially fixed it for in-mem in that it no longer made the
server panic, but it was returning incorrect results. Additional work
ended up being needed for in-mem search.
