According to Dolibarr roadmap, freeze of version 7.0 has started. There is a lot of exiting enhancements in this version.
The Pull Requests with tags "To merge" are still qualified to be merged even after the freeze, but it does not means they will be.
The branch 7.0 will be created later, during december, once first main bug fixes are received.
If you develop external modules, please test as soon as possible your modules with the beta version and help us to debug/fix this version 7.0
