Today is the final day to submit new packages to the Bioconductor contributions tracker to have a shot at being included in the upcoming 3.7 release at the end of the month. 
https://github.com/Bioconductor/Contributions

Please note: submission today does not guarantee it will be included - the package must undergo an official review and be accepted by April 16th. 

Submissions after today and those that are not accepted by April 16th will still be able to be in Bioconductor but will be included in the 3.8 release later in the year. 

Please see the release schedule for other important deadlines

Cheers,
