just like during release of Moodle 3.1 we need extra time to polish our new features, especially new theme Boost based on Bootstrap 4. Theme has already been integrated under MDL-55071 and you can take a look at it on qa.moodle.net or test on your development servers with your plugins while we are working on the follow ups.We do not want to start other pre-release tasks such as community QA cycle and documentation writing before the polishing is finished. Therefore we decided to move the release date by two weeks and instead of planned second Monday of November it will happen on 28th of November.
As a result the code freeze is also moving by two weeks and will happen on 24th of October.
Minor releases of stable versions will comply with the regular release schedule and are still expected on November 14.
