## [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.
## [3.7.13.2] - 2018-05-31
### Fixed
#### Project Scope
- 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.
## [3.7.13.1] - 2018-05-31
### Fixed
#### Project Scope
- Actually bumped version in CMakeLists.txt
## [3.7.13.0] - 2018-05-31
### Fixed
#### Project Scope
- `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
#### GRC
- Fixed GRC bug which broke WX and Qt (by altering the template code), in multiple (less than awesome) steps
#### gr-blocks
- `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
## [3.7.12.0] - 2018-04-01
### Software Engineering
- 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.
### Fixed
#### Project Scope
- Buildability on systems where custom CMake command would try to find "" (empty string) as executable
- Buildable with C++11 compilers (though deprecation warning-rich, due to `unique_ptr`)

ChangeLog v3.7.10.1
This is the first bug-fix release for v3.7.10
This contains bug fixes primarily for GRC and DTV.
- GRC
* Catch more exceptions thrown by ConfigParser when reading corrupted
grc.conf files.
* Fix the docstring update error for empty categories.
* Fix grcc to call refactored GRC code.
* Convert initially opened files to absolute paths to prevent
attempting to read from tmp.
* Move startup checks back in to gnuradio-companion script from grc/checks.py.
- DTV
* Fix a segfault that occurs from out-of-bounds access in
dvbt_bit_inner_interleaver forecast by forecasting an enumerated list
of all input streams.
* Fix VL-SNR framing.
- Digital
* Enable update rate in block_recovery_mm blocks to keep tags close to
the the proper clock-recovered sample time. Tag offsets will still be
off between calls to work, but each work call updates the tag rate.
- Analog
* Fix the derivative calculation in fmdet block.
- Builds
* Fix linking GSL to gr-fec.
* Use gnu99 C standard rather than gnu11 standard to maintain
support for GCC 4.6.3.
- Other
Minor spelling and documentation fixes.
Fix uhd_siggen_gui when using lo_locked.
(pkgsrc changes on gnuradio-core/Makefile.common)
- Following lines added
CXXFLAGS+= -pthread
.include "../../devel/cppunit/buildlink3.mk"
.include "../../math/gsl/buildlink3.mk"
-----------------------------------------
GNU Radio releases 3.7.6 and 3.7.5.2 are available for download:
( several tens of lines omitted for URL and List of contributors)
Release 3.7.5.2 is a bug-fix only maintenance patch following 3.7.5.1,
and will be the last one for the 3.7.5 release. Release 3.7.6
incorporates all these fixes and adds significant new features.
