January 2020 Osmocom CNI releases
The Osmocom project has released new version 202001 of the CNI (Cellular Network Infrastructure) software, including OsmoTRX, OsmoBTS, OsmoPCU, OsmoBSC, OsmoMGW, OsmoMSC, OsmoHLR, OsmoSGSN, OsmoGGSN, OsmoSTP, OsmoSIPConnector, and others.
Those new tagged/released versions contain five months of work since the previous versions released during August 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.

- Several crashes fixes, robustness and logging improved
OsmoMSC¶
- Improvements in SGs interface and CSBF
