Project Scope
^^^^^^^^^^^^^

-  Fix Boost 1.67 linking issue

-  ``clock_recovery_cc``, ``crc32_bb``: Accessing the ``[0]`` element of
   an empty vector is UB, even if you don't use the result afterwards.

   .. rubric:: gr-fec
      :name: gr-fec

-  ``polar_encoder``/``_common``: Fixed multiple out-of-bound accesses
   due to insufficient vector length checks

\## [3.7.13.3] - 2018-06-13

\### Fixed
\#### Project Scope
- For non-C++11 compilers, the new cstdint include doesn't work out; conditionalized it.

All notable changes to GNU Radio will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html), starting with version 3.7.12.0.

Older Logs can be found in `docs/RELEASE-NOTES-*`.

- Actually bumped version in CMakeLists.txt to 3.7.13.2; the 3.7.13.1 tag was tagged off-branch; maintainer failure to simultaneously push a commit that raises the internal version number to 3.7.14.0: this had to be reverted ASAP.

- Actually bumped version in CMakeLists.txt

- `boost::posix_time::[milli]second` takes integer numbers, and we now at least cast the floats to integers, as Boost 1.67 forced us to realize we're (incorrectly) using floating point her
- CMake: using regex to match compiler against "Clang" now enables correct build on OS X
- Fixed GRC bug which broke WX and Qt (by altering the template code), in multiple (less than awesome) steps
- `float_array_to_int`: int32 limits were wrongly hardcoded.
- Fixed the undefined behaviour happening in `float_to_complex` when accessing the second input_items element in the single-input case

- Changed Changelog format
- Introducing Semantic Versioning
- Change of development model: Rather than merging bugfixes to maint, merging maint to master, and next, if applicable, we'll be moving forward more in a typical management model: Development happens on master, and bugfixes are cherrypicked onto the maint-${RELEASE} branch. More info: http://lists.gnu.org/archive/html/discuss-gnuradio/2018-02/msg00133.html
- First attempt at having a .clang-format file to improve code contribution style quality. This is Work In Progress.
