The development (master) branch of Kamailio enters now in pre-release phase for version 5.0.0. Therefore, no new feature should be pushed to master until we create a dedicated branch for 5.0 (expected to be in about 4 weeks or so).
If in doubt to push or not a commit to master branch, push it first on a personal branch (or attach to an email) and discuss it on sr-dev mailing list. The new modules can be a bit more dynamic if there is need to get them to the right shape (e.g., like decision to rename functions, parameters or adjust database structure).
We hope to get many people involved in testing, to reach a stable state before releasing 5.0.0. If you want to get involved and need assistance, don’t hesitate to write to mailing lists.
Besides the new features, there were two major changes for 5.0:
source code tree restructuring – this should not affect the stability of the code, only installation scripts or packaging may still need tuning
mi (management/control interface) code has been removed. SIP routing code should not be affected by this change that much, but testing of RPC commands needs a special care. There are few RPC commands not ported yet from the MI code, they can be done during the testing period
Moreover, help with updating the wiki page for migration from 4.4 to 5.0 as well as what is new in 5.0 is very appreciated. More updates about them very soon.
Many thanks to everyone involved in development of 5.0 and the early testers that played with master branch so far.
