As part of the NITB-Split and repository reorganisation, we have moved the GPRS code that used to live in openbsc.git to a separate repository.
Technically, the OsmoSGSN, GbProxy and GTPHUB never shared any code with osmo-nitb or the other circuit-switched code in openbsc.git. It was probably a bad idea to start writing the code in the same repository at all.
Effective today, the GPRS components have been removed from openbsc.git. Please use osmo-sgsn.git from now on. Sorry for any inconvenience caused.
