Originally published on libvolk.org Hi everyone! We have a new VOLK release! We are happy to announce VOLK v2.5.1! We want to thank all contributors. This release wouldn’t have been possible without them. The list of contributors is pretty long this time due to a lot of support to relicense VOLK under LGPL.
The last six months brought a small number of changes regarding the GNU Radio project. Time to give an update! General Assembly September 2021 In September 2021, prior to GRCon, the General Assembly met for a “synchronous meeting” (which is what we call official events with real-time voting/elections). The meeting mainly comprised of the Board giving an update on activities and finances, an election of the Board, and votes on new members to the GA.
We are pleased to announce a new set of beginner-level tutorials, as well as a new tutorials landing page, you can check them out here A big thank you to NumFOCUS for sponsoring the work and to Matt from wavewalkerdsp who did the bulk of the work! These beginner-level tutorials walk a new user through starting GRC and creating a simple flowgraph, all the way up to creating custom blocks and using tags and message passing.
Release 3.10.0.0 [3.10.0.0] - 2022-01-14 It is with much excitement that we release the next step forward for GNU Radio - 3.10.0.0! Not only does this release bring in some extremely useful new modules (gr-iio, gr-pdu, and arguably gr-soapy thought that thankfully made it also into recent 3.9 maintenance releases), but also sets a path forward for using GNU Radio in heterogeneous compute environments by providing “custom buffers” for more efficiently interacting with accelerators (GPUS, FPGAs, TPUs, etc.
The Signal Metadata Format (SigMF) specifies a way to describe sets of recorded digital signal samples with metadata written in JSON. SigMF can be used to describe general information about a collection of samples, the characteristics of the system that generated the samples, features of signals themselves, and the relationship between different recordings.
Just as the year closes, it’s time to remind people that a fantastic event is going to take place at the beginning of February: FOSDEM 2022 FOSDEM is the Free- and Open Source conference in Europe! GNU Radio has had a strong presence there for the last few years, and 2022 will be no different.
GNU Radio Conference 2021 was a great success, with around 100 in-person attendees and over 1000 remote attendees! Talks were split between in-person and remote (pre-recorded). All talks are now available to watch on YouTube, you can find a playlist that includes all videos here. You can also look through the schedule of talks which contains more info about each talk, note that each day is in a different tab.
We are officially ending maintenance of v3.7. There will be no further v3.7.X.X releases, and pull requests will no longer be accepted for the maint-3.7 branch. The last v3.7 release (v3.7.14.0) was over 18 months ago and there are only a handful of unreleased commits on the maint-3.7 branch. Packagers/distributions have moved on to newer versions.
Release 3.9.4.0 [3.9.4.0] - 2021-10-25 This is an API compatible update to GNU Radio 3.9. Code written for 3.9.X versions should compile and link without modification. The ABI is not guaranteed to be compatible, so a rebuild of OOT modules may be necessary. Changes Regressions Fixes Remove #include <filesystem> (C++17 feature) from one file Restore pyqwidget() in gr-qtgui GRC GRC now runs on Fedora 35 … Gtk initialization checks were too strict Add keyboard shortcuts for zoom Account for scale factor when computing drawing area size Use font size from config for block comments Change type aliasing to allow interleaved short/byte to be connected to vectors of short/byte.
The September updates for GNU Radio are out. Here is the changelog summary for v3.8.4.0.
