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

As Ubuntu 18.04 (Bionic Beaver) has been released two days ago, Osmocom has enabled Binary_Packages builds for this new distribution in both nightly and latest. As a result, you can now use our binary package feeds on this most recent incarnation of Ubuntu just like on the other supported distributions.
This was relatively easy due to the openSUSE Build Service (OBS) immediately adding support for Ubuntu 18.04. so all we had to o is enable it, and fix up some minor failures. Thanks to OBS for making supporting new distributions very easy!
