----------------------

**Announcement**

* Curator is tested in Jenkins. Each commit to the master branch is tested
with both Python versions 2.7.6 and 3.4.0 against each of the following
Elasticsearch versions:
* 1.7_nightly
* 1.6_nightly
* 1.7.0
* 1.6.1
* 1.5.1
* 1.4.4
* 1.3.9
* 1.2.4
* 1.1.2
* 1.0.3
* If you are using a version different from this, your results may vary.

**General**

* Allocation type can now also be ``include`` or ``exclude``, in addition to
the existing default ``require`` type. Add ``--type`` to the allocation
command to specify the type. 443 (steffo)

* Bump elasticsearch python module dependency to 1.6.0+ to enable
synced_flush API call. Reported in 447 (untergeek)

* Add SSL features, ``--ssl-no-validate`` and ``certificate`` to provide
other ways to validate SSL connections to Elasticsearch. 436 (untergeek)

**Bug fixes**

* Delete by space was only reporting space used by primary shards. Fixed to
show all space consumed. Reported in 455 (untergeek)

* Update exit codes and messages for snapshot selection. Reported in
452 (untergeek)

* Fix potential int/float casting issues. Reported in 465 (untergeek)

--------------------

**Bug fix**

* In order to address customer and community issues with bulk deletes, the
``master_timeout`` is now invoked for delete operations. This should
address 503s with 30s timeouts in the debug log, even when ``--timeout`` is
set to a much higher value. The ``master_timeout`` is tied to the
``--timeout`` flag value, but will not exceed 300 seconds. 420 (untergeek)

**General**

* Mixing it up a bit here by putting `General` second! The only other
changes are that logging has been improved for deletes so you won't need to
have the ``--debug`` flag to see if you have error codes >= 400, and some
code documentation improvements.

--------------------

**General**

* This is a very minor change. The ``mock`` library recently removed support
for Python 2.6. As many Curator users are using RHEL/CentOS 6, which is
pinned to Python 2.6, this requires the mock version referenced by Curator
to also be pinned to a supported version (``mock==1.0.1``).
