February 2021 Osmocom CNI releases

Added by pespin about 2 months ago

The Osmocom project has released new version 202102 of the CNI (Cellular Network
Infrastructure) software, including OsmoTRX, OsmoBTS, OsmoPCU,
OsmoBSC, OsmoMGW, OsmoMSC, OsmoHLR, OsmoSGSN,
OsmoGGSN, OsmoSTP,
osmo-sip-conector, and others.

Those new tagged/released versions contain in some cases up to one year of work
since the previous versions released during January 2020 (on some projects,
patch and intermediate releases were done during the year). The primary focus
was on bug-fixing and stabilization as well as some major new features, such as
IPv6 support.

You can find pre-compiled binary packages of our latest release for a variety of
Debian and Ubuntu GNU/Linux versions at
Latest_Builds.
