-------------------
- A tool for migrating/reindexing elasticsearch (reindex.py) was added (103).
- The store returns more appropriate HTTP response codes (96).
- Dropped support for ElasticSearch versions before 1.0.0 (92).
- The default search query has been changed from a term-filtered "match all" to
a set of "match queries", resulting in more liberal interpretations of
queries (89).
- The default elasticsearch analyzer for annotation fields has been changed to
"keyword" in order to provide more consistent case-sensitivity behaviours
(73, 88).
- Made Flask an optional dependency: it is now possible to use the persistence
components of the project without needing Flask (76).
- Python 3 compatibility (72).
