This release took longer than expected for a few reasons. Big changeset, we wanted to test all more time to make sure all works as expected. We also wanted to backport as much from the development branch as we could. End of support for 1.2.x will not come sooner than 2021, but starting with 1.2.6, we’ll focus on bug fixes and security updates. Big improvements we are making in the future 1.3.x branch demands big internal changes, so we want to focus on stabilizing it and making a stable 1.3.0 release by the end of 2020.
