The final day to submit new packages to the Bioconductor contributions tracker to have a shot at being included in the upcoming 3.13 release is Friday April 23rd.

Please note: submission by this date does not guarantee it will be included; this ensures at least an initial review and depending on speed of revisions possible re-review if necessary. The package must undergo an official review and be accepted by Wednesday May 12th to be formally included in this Spring release.

Submissions after Friday April 23rd and those that are not accepted by May 12th will still be able to be in Bioconductor but will be included in the development branch until the 3.14 release this coming Fall.
