[sr-dev] Pull request development workflow

[Luis Martin Gil]

Hi,

A couple of _PRs_ were merged into the master branch back in June 2016, see [this](https://github.com/kamailio/kamailio/pull/667) and [this](https://github.com/kamailio/kamailio/pull/664). 

I believed Kamailio versions released after such _PRs_  were going to include such changes, but latest Kamailio stable (version [4.4.0](https://www.kamailio.org/w/kamailio-v4-4-0-release-notes/)) doesn't include them. This assumption is wrong and I was wondering how this works in the actual Kamailio developement workflow: when can I expect to have such _PRs_ included?

Thanks!
Luis
