The second release candidates of 5.2.15 and 5.3.4 were just released for testing and can be downloaded here:

Since the first release candidate, we have not seen a large number of changes and and there are no show-stopper bugs for either version. At this point we both feel that the next logical step is the final release, which we would like to schedule a week from now.
Given that this is the case, we would like to ask all developers to refrain making commits to the 5.3 and 5.2 branches, unless these constitue critical bug fixes, in which case please let Johannes and myself know about these fixes ahead of time. This way we can avoid last minute regressions, especially so for the 5.2.15 release, which is the final one in that series.
