August 2019 Osmocom CNI releases

New versions of the Osmocom Cellular Network Infrastructure have been released
Added by laforge about 2 months ago

It seems we forgot the release announcement in early August:

The Osmocom project has released new version of the CNI (Cellular Network Infrastructure) software, including OsmoTRX, OsmoBTS, OsmoBSC, OsmoMGW, OsmoMSC, OsmoHLR, OsmoSGSN, OsmoGGSN.

Those new tagged/released versions contain four months of work since the previous versions released during April 2019. The primary focus was on bug-fixing and stabilization as well as some major new features, such as inter-MSC-handover support in osmo-msc.

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