New Osmocom Cellular software versions released!

Added by laforge 11 days ago

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

Thosw new tagged/released versions contain half a year of work since the previous versions released in early November 2017. The primary focus was on bug-fixing and stabilization. Many bugs were introduced during the split of the NITB into individual network elements during 2017, and even more bugs exposed by our ever-growing test coverage, particularly in the Osmocom TTCN-3 test suites.

All-in-all, the post-NITB stack has gained a lot in terms of spec compliance, robustness, stability and features during this period.

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

The developer performing the release related work was Pau Espin. Thanks!
