* SECURITY: Fix lxc_container module having predictable temp file names and setting file
permissions on the temporary file too leniently on a temporary file that was
executed as a script. Addresses CVE-2016-3096
* Fixed bugs related to the iteration of tasks when certain combinations of roles,
blocks, and includes were used, especially when handling errors in rescue/always
portions of blocks.
* Fixed some bugs in the URI module related to redirects and SSL handling.
* Fixed some bugs related to the incorrect creation of extra temp directories for
uploading files, which were not cleaned up properly.
* Fixed a bug related to the variable precedence of role parameters, especially when
a role may be used both as a dependency of a role and directly by itself within the
same play.
* Fixed some bugs in the 2.0 implementation of do/until.
* Fixed some bugs related to run_once:
- Ensure that all hosts are marked as failed if a task marked as run_once fails.
- Show a warning when using the free strategy when a run_once task is encountered, as
there is no way for the free strategy to guarantee the task is not run more than once.
* Fixed a bug where the assemble module was not honoring check mode in some situations.
* Fixed a bug related to delegate_to, where we were incorrectly using variables from
the inventory host rather than the delegated-to host.
* The 'package' meta-module now properly squashes items down to a single execution (as the
apt/yum/other package modules do).
* Fixed a bug related to the ansible-galaxy CLI command dealing with paged results from
the Galaxy server.
* Pipelining support is now available for the local and jail connection plugins, which is
useful for users who do not wish to have temp files/directories created when running
tasks with these connection types.
* Improvements in support for additional shell types.
* Improvements in the code which is used to calculate checksums for remote files.
* Some speed ups and bug fixes related to the variable merging code.
* Workaround bug in python subprocess on El Capitan that was making vault fail
when attempting to encrypt a file
* Fix a bug in the uri module where setting headers via module params that
start with HEADER_ were causing a traceback.
* Fix bug in the free strategy that was causing it to synchronize its workers
after every task (making it a lot more like linear than it should have been).
