[3.7.13.4] - 2018-07-15
-----------------------

Fixed
~~~~~

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

-  Fix Boost 1.67 linking issue

   .. rubric:: gnuradio-runtime
      :name: gnuradio-runtime

-  Logging: fixed issues where messages weren't properly written to
   stdout/stderr due to incorrect strings

   .. rubric:: gr-analog
      :name: gr-analog

-  ``fmdet_cf``'s derivative coefficients were wrong.

   .. rubric:: gr-blocks
      :name: gr-blocks

-  ``skiphead`` used to incorrectly handle tags, now properly shifts

   .. rubric:: gr-digital
      :name: gr-digital

-  ``qa_packet_format``: Unit test used to potentially lock up due to
   incorrect conditionals
-  ``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

   .. rubric:: gr-filter
      :name: gr-filter

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

\## [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.

Major Development Areas
-----------------------

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.

Code
----

This release includes a number of minor typos and miscellaneous
rewording of\
error messages. The following sections summarize substantial changes.

-   the ‘Parser errors’ menu item wasn’t correctly enabled
-   embedded python blocks: message ports are now optionial and show the
    correct label
-   custom run command now accounts for filepaths that need escaping
-   virtual sink/source message connections were dropped when opening a
    flow graph
-   tooltips in block library are truncated if too long
-   not all tooltips in block library were updated after docstring
    extraction finished
-   some expressions were wrongfully marked invalid after opening a flow
    graph
-   move random uniform source from analog to waveform generators in GRC

A new unit test is available to test a bug reported on stack overflow
where blocks (such as the delay block) would drop tags. Paul David stepped in
with his first contribution to GNU Radio with a fix.

Fix an issue with flat\_flowgraph calculating alignment by
misinterpreting units of write and read indeces. This was only apparent when these
indeces are non-zero (a flowgraph has stopped and restarted).

Fix exceptions thrown in hier\_block2 constructors.

Check d\_ninput\_items\_required for overflow and shut down if
overflow is detected.

Allow hier\_block2’s to change I/O signature in the constructor, which
was previously allowed by the API, but broken.

Use unsigned char rather than char in add\_const\_bb. This was the
legacy behavior with the older add\_const\_XX and was accidentally
replaced with char when replacing the templated version.

Fix vector length units from bytes to number of items in PDU to tagged
stream and tagged stream to PDU blocks.

Add a check to the rational resampler to stop working after we’ve
operated on all input items (closed issue \#831)

Throw an error when pfb clock sync is given constant taps which results
in a derivative of 0 (calculated as NaN). (closed issue \#812 and 734). Added
a reset\_taps function to externally set taps which should be used in
place of set\_taps.

Fix a memory leak in pfb decimator (closed issue \#882)

Maximum Deviation parameter for NBFM transmitter exposed to GRC

Change the constellation receiver to inherit from control\_loop
publically
rather than the impl to better support the control port interface.
(closed issue \#876)

TLC to puncture/depuncture GRC files in gr-fec

Major performance and correctness fixes to gr-zeromq

Fix cross compiling on for 64-bit architectures by not setting DEBIAN,
REDHAT, and SLACKWARE. OOT modules created with modtool should update their
cmake/Modules/GrPlatform.cmake to support cross 64-bit builds.
