- gr-pdu: Protocol Data Units library
- gr-iio: Linux industrial I/O library (but not packaged in pkgsrc)
- Custom Buffers Support
- switch from Log4CPP to spdlog
Changed
SoapySDR support (gr-soapy)
GRC
Parameter expressions and/or values can be displayed in blocks on the flowgraph. Previously, only values were displayed. Look for the "Show Parameter ..." toggles under the View menu.
Deprecated blocks are shown in a distinct color (orange), and the optional deprecated property has been added to block yaml
Dark theme works better, especially for parameter fields
Vector length is now correctly applied to all input ports
Validation has been improved. Raw types are validated. Port connections are checked by type rather than by item size.
Variable names that cause name conflicts in Python code (e.g., with package names) are rejected
Bus logic fixes
Blocks can no longer be dragged off the screen and lost forever
gnuradio-runtime
Remove pmt::pmt_* functions, which were not actually implemented. This is technically an API change, but any use of the API would have resulted in a link error.
Remove Python bindings for internal buffer functions
gr-analog
Added an example for PLL Frequency Detector
Better names for parameters in PLL GRC blocks
gr-blocks
Consistent naming for Vector Length parameter in GRC blocks
count_bits uses VOLK popcnt for better performance (used for example in the Correlate Access Code block)
Rotator block phase increment parameter is controllable via a message, and a tag can be added at the point where the increment is adjusted
gr-digital
MPSK example updated to use a Linear Equalizer (replacing deprecated block)
gr-filter
Filter Delay documentation improvement
Interpolating FIR filter can generate C++ code
gr-dtv
VL-SNR bugs fixed (incorrect constants).
gr-qtgui
Improve autoscaling for vector sinks
Fix floating-point resolution problems in several widgets, due to interpretation of PMT doubles as floats
gr-uhd
Add policy enum to Python bindings for tune_request
Additional time spec options on UHD blocks (PC Clock on Next PPS, GPS Time on Next PPS)
Fix up code that was generating warnings
Fix command handler logic to apply commands from messages to the correct channel
gr_filter_design
"File/Save" is disabled until the taps have been computed, and the GUI is reset after a save, to make it clearer which data is being saved.
Entries are hidden for parameters that do not apply to the selected filter type.
Save window type as an integer instead of a Python enum name
gr_modtool
Improve validation of module and block names
Build System and Infrastructure
Improved messages related to dependencies MPIR and GMP. Only one of these packages is required, and the previous error messages were confusing.
Cleaner builds for Windows and Conda. A number of general cmake improvements have resulted from this work.
In-tree packaging files for DEB and RPM, used with Launchpad and COPR
Added man pages for GNU Radio tools
Test code generation for all in-tree GRC examples
In GrPybind.cmake, PYBIND11_INCLUDE_DIR (incorrect) was changed to
pybind11_INCLUDE_DIR
This yields one common package to provide libfftw3 (double) and libfftw3f
(single) by default and optionally the Fortran bindings as well as
OpenMP and MPI variants, and those with long double or quad precision.
This changes all packages depending on fftwf in the same commit to minimize
the time of inconsistency. Soon, math/fftwf will disappear.

## [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

- `get_tags_in_range` used `v.resize(0)` to clear vectors, which lead to unnecessary memory reallocations

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.
