# Release 3.8.0.0
Witness me!
Tonight, we release GNU Radio 3.8.0.0.
It's the first minor release version since more than six years, not
without
pride this community stands to face the brightest future SDR on general
purpose
hardware ever had.
Since we've not been documenting changes in the shape of a Changelog
for the
whole of the development that happened since GNU Radio 3.7.0, I'm
afraid that
these release notes will be more of a GLTL;DR (git log too long; didn't
read)
than a detailed account of what has changed.
What has _not** changed is the fact that GNU Radio is centered around a
very
simple truth:
Let the developers hack on DSP. Software interfaces are for humans,
not the
other way around.
And so, compared to the later 3.7 releases, nothing has fundamentally
modified
the way one develops signal processing systems with GNU Radio: You
write blocks,
and you combine blocks to be part of a larger signal processing flow
graph.
With that as a success story, we of course have faced quite a bit of
change in
the systems we use to develop and in the people that develop GNU Radio.
This has
lead to several changes that weren't compatible with 3.7.
**This is an excerpt only:**
## Fixed
### Project Scope
- Roughly 36 dBBug, (ETOOMANYBUGS)
- Fixed .so versioning
## Changed
### Project Scope
- C++11
- merged the wholeness of the `next` branch
- Dependency version bumps: CMake, GCC, MSVC, Swig, Boost
- New dependencies: MPIR/GMP, Qt5, gsm, codec2
- Removed dependencies: libusb, Qt4, CppUnit
- Python: Python 2 & Python 3 compatible. 3.8 will be the last
Py2k-compatible
release series
- gengen was replaced by templates (if you don't know gengen, don't do
any
research; save yourself that sorrow)
- Modern CMake (as far as feasible at this point)
- VOLK version updated to v2.0.0
- .clang-format file now dictates coding style
- clang-format'ed the whole tree.
- installed CMake files now tell about configuration
### gnuradio-runtime
- reworked fractional tag time handling, especially in the context of
resamplers
### GRC
- C++ generation as option
- YAML instead of XML
- removed `blks2`
- much better canvas tooling
- consistent gobject usage
- ROUNDED ARROWS
### gr-qtgui
- moving from Qt4 to Qt5
### gr-utils
- `gr_modtool` now vastly improved
### gr-vocoder
- improved versatility
- removed in-tree libgsm, libcodec2, use system-wide libs
## Removed
### Project Scope
- Modules `gr-comedi`, `gr-fcd` and `gr-wxgui` are gone
### gr-comedi
- nobody could remember who used this, or for what. It has seen 0
active code
contributions in the 3.7 lifecycle
### gr-digital
- python-based `packet_encoder` and related tools: Bugs that were
sporadic and
never fixed, so after long deprecation, we're removing it
### gr-fcd
- since it's currently untestable by the CI, it's being removed, as
there was no
code contributions. Generally, we strive to include all batteries
with GNU
Radio. Re-integration within a more general SDR interface would be
desirable.
### gr-utils
- removed PyQwt (dead) based tools
### gr-wxgui
- Unmaintained, breaks on increasingly many systems, always was slower
than
Qtgui. We've been starting to tell people to migrate to Qt since at
least 2015. Now, we're finally removing it.
