All notable changes to GNU Radio will be documented in this file.
The format is based on Keep a Changelog and this project adheres to Semantic Versioning, starting with version 3.7.12.0.
Older Logs can be found in docs/RELEASE-NOTES-*
.
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
- 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.
- 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
) - several previously improperly handled include directories now actually included in individual lib/CMakeLists
- Unit test/QA now parallelizable
- Logger works with log4cpp <= 1.1.2 both in and out of tree
- Python linkage under MinGW64
- Documentation Directory now uniformly "docs/" (instead of sometimes "doc/")
log
vslogf
performance bugs- on-time
pmt::mp("string")
calls (instead of cached PMTs) performance bug - Doxygen build now reproducible
- Dialogs' parent windows
- Embedded Python Blocks now work in hierarchical GRC flow graphs
random.h
: Uniform integer Generation depended on Boost version > min versionrandom.h
: time-dependency when seeding with0
replaced with actual standard seed- block startup now synchronized via barrier
- New tag propagation policy "custom" for own implementation
get_tags_in_range
usedv.resize(0)
to clear vectors, which lead to unnecessary memory reallocationslogger_ptr
now always a pointer, no matter whether logging is enabled; fixes heap corruption bugbuffer[_reader]_sptr
superfluous grab/release performance bug- BSD threading and shared mem compatibility
- PMT:
equal()
comparison
- Sorted files in
gr_modtool
makexml processing, leading to improved reproducibility of builds
- OS X: memcpy bug
- OS X: debug mode
- Non-Linux ALSA compatibibilty

Ctrlport example- Metadata sink/source not closing file on
close()

selective_fading_model
: proper scaling of path length
additive_scrambler_bb
: tag triggered resetstream_to_tagged_stream
: tag offset afterunlock()
blks2/packet.py
: Flushing for small packetsinterpolating_resampler
: GCC 4.0 compile errorconstellation
: 16QAM demapper was wrong for one constellation pointchunks_to_symbols
: mutex-guard LUT against modification during use- MSVC compatibility throug
and
