Upstream doesn't build support for these devices by default anymore:
> The actual osmosdr had only a very limited production run many years
> ago and is therefore of little interest to most gr-osmosdr users.
> Mirisdr was experimental at best, because the dongles were never
> widely avaialble outside of Japan and had multiple unconnected antenna
> ports.
Here is a very high level list of changes:
## 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.
Upstream does not have release notes (or releases).
chirp now tracks upstreams "chirp-daily" pseudoreleases, labeled by
date. The package remains "chirp"; upstream only calls it chirp-daily
due to some GNU/Linux packaging issues.
This is a huge update as 0.4.1 is from many years ago.
Note that the previous gnuradio-core package conflicts with math/volk.
In order to update you must delete the old gnuradio-core package so
that math/volk can first be installed.
SoapySDR is an open-source generalized API and runtime library for interfacing
with SDR devices. With SoapySDR, you can instantiate, configure, and stream
with an SDR device in a variety of environments. Most off the shelf
SDR hardware platforms are supported by SoapySDR, and many open source
applications rely on SoapySDR for hardware integration support. In addition,
SoapySDR has bindings for development frameworks like GNU Radio and Pothos.
Release 2.2.6:
By John A. Magliacane <kd2bd@amsat.org> (20-May-2020):
* The installer program has been replaced by a bash script that
configures, compiles, and installs PREDICT and several companion
client utility applications.
* The SingleTrack and MultiTrack displays have been modified for
more consistent performance across a wider range of terminals.
* PREDICT's "vocalizer" now employs the Advanced Linux Sound
Architecture (ALSA) environment instead of OSS in response
to recent changes in v5.6 and later Linux kernels.
* The handling of geosynchronous and geostationary satellites
has been improved, but still needs to be used with caution.
* 100 MHz normalized downlink Doppler shift information has been
added to all -p and -f command-line outputs.
* The documentation and the transponder database file have been
updated, and the format of the man page has been corrected.
Release 2.2.5:
By John A. Magliacane <kd2bd@amsat.org> (05-May-2018):
* Fixed coding bugs identified by GCC v8.1.0.
* Re-arranged GCC arguments in installer.c for better
compatibility with more recent versions of GCC.
* Added a -dp command-line option to PREDICT to
provide quick Doppler shift estimates in CSV format.
(Thanks Joeal Subash)
* Updated the documentation to reflect the changes.
----------------------------------------------------------------------------
Release 2.2.4:
By John A. Magliacane <kd2bd@amsat.org> (12-Mar-2018):
* Fixed a bug affecting the -f switch that sometimes caused
a failure to return proper output. (Tnx: Andrej Lajovic)
* Fixed a bug in installer.c that sometimes caused a failure
to properly install PREDICT's executable into /usr/local/bin
by default.
* Added <errno.h> header to gsat-1.1.0/src/callbacks.c
