Monday March 31st will mark the current Release 3.20 freeze. The RELEASE_3_20 branch will be frozen and no longer accept commits as of this coming Monday March 31. Any changes or bug corrections that are not pushed up by Monday (noon EST) will not be in the Bioconductor 3.20 branch of the package as we do not allow updates to past/frozen release.
You still may push to the Bioconductor devel branch at any time. The devel branch is considered a release candidate at this time; Please do not push up major API changes and limit to debugging for clean build/check reports.
