Curator-opensearch

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

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

**Bug Fixes**

* The certifi-provided certificates were not propagating to the compiled
RPM/DEB packages. This has been corrected. Reported in 810 (untergeek)

**General**

* Added missing ``--ignore_empty_list`` option to singleton actions.
Requested in 812 (untergeek)

**Documentation**

* Add a FAQ entry regarding the click module's need for Unicode when using
Python 3. Kind of a bug fix too, as the entry_points were altered to catch
this omission and report a potential solution on the command-line. Reported
in 814 (untergeek)
* Change the "Command-Line" documentation header to be "Running Curator"

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

**Bug Fixes**

* In the course of package release testing, an undesirable scenario was
caught where boolean flags default values for ``curator_cli`` were
improperly overriding values from a yaml config file.

**General**

* Adding in direct download URLs for the RPM, DEB, tarball and zip packages.

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

**New Features**

* Shard routing allocation enable/disable. This will allow you to disable
shard allocation routing before performing one or more actions, and then
re-enable after it is complete. Requested in 446 (untergeek)
* Curator 3.x-style command-line. This is now ``curator_cli``, to
differentiate between the current binary. Not all actions are available,
but the most commonly used ones are. With the addition in 4.1.0 of schema
and configuration validation, there's even a way to still do filter
chaining on the command-line! Requested in 767, and by many other
users (untergeek)

**General**

* Update testing to the most recent versions.
* Lock elasticsearch-py module version at >= 2.4.0 and <= 3.0.0. There are
API changes in the 5.0 release that cause tests to fail.

**Bug Fixes**

* Guarantee that binary packages are built from the latest Python +
libraries. This ensures that SSL/TLS will work without warning messages
about insecure connections, unless they actually are insecure. Reported in
780, though the reported problem isn't what was fixed. The fix is needed
based on what was discovered while troubleshooting the problem. (untergeek)

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

This release does not actually add any new code to Curator, but instead
improves documentation and includes new linux binary packages.

**General**

* New Curator binary packages for common Linux systems!
These will be found in the same repositories that the python-based packages
are in, but have no dependencies. All necessary libraries/modules are
bundled with the binary, so everything should work out of the box.
This feature doesn't change any other behavior, so it's not a major
release.

These binaries have been tested in:
* CentOS 6 & 7
* Ubuntu 12.04, 14.04, 16.04
* Debian 8

They do not work in Debian 7 (library mismatch). They may work in other
systems, but that is untested.

The script used is in the unix_packages directory. The Vagrantfiles for
the various build systems are in the Vagrant directory.

**Bug Fixes**

* The only bug that can be called a bug is actually a stray ``.exe`` suffix
in the binary package creation section (cx_freeze) of ``setup.py``. The
Windows binaries should have ``.exe`` extensions, but not unix variants.
* Elasticsearch 5.0.0-beta1 testing revealed that a document ID is required
during document creation in tests. This has been fixed, and a redundant
bit of code in the forcemerge integration test was removed.

**Documentation**

* The documentation has been updated and improved. Examples and installation
are now top-level events, with the sub-sections each having their own link.
They also now show how to install and use the binary packages, and the
section on installation from source has been improved. The missing
section on installing the voluptuous schema verification module has been
written and included. 776 (untergeek)

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

**Bug Fixes**

* String-based booleans are now properly coerced. This fixes an issue where
`True`/`False` were used in environment variables, but not recognized.
765 (untergeek)

* Fix missing `count` method in ``__map_method`` in SnapshotList. Reported in
766 (untergeek)

**General**

* Update es_repo_mgr to use the same client/logging YAML config file.
Requested in 752 (untergeek)

**Schema Validation**

* Cases where ``source`` was not defined in a filter (but should have been)
were informing users that a `timestring` field was there that shouldn't
have been. This edge case has been corrected.

**Documentation**

* Added notifications and FAQ entry to explain that AWS ES is not supported.
