There is a new bugfix release for the old 0.9.x ser (if you are using a 2.x version or sip-router, please disregard this message). The release is made from the top of the rel_0_9_0 branch (so if you already have a ser version compiled from the top of rel_0_9_0 in the last 10 month you don't need to upgrade). It contains 3 more fixes when compared to 0.9.7: - tm: fix delete_cell() when the transaction is referenced - core: fix memory leak in subst_user - acc: misspeled function name and wrong check You can either get it from cvs (v_0_9_8 tag or the top of rel_0_9_0 branch) or you can download a tarball with the sources: http://ftp.iptel.org/pub/ser/0.9.8/src/ser-0.9.8_src.tar.gz. There are no binary packages provided, only sources. Upgrading from older 0.9.x versions should only involve re-compiling and re-installing ser. There are no changes in the config file format or in the DB schemes. Andrei
