BioC community,

Starting with BioC 3.6 we are providing an Archive directory for each release. The Archive contains all package versions that occur during the 6 month cycle. This will be done for the release branch only.

The structure is similar to the CRAN Archives except there will be a separate Archive for each version of Bioconductor. You can see the 3.6 Archive here:

  http://bioconductor.org/packages/3.6/bioc/src/contrib/Archive/

If a package has multiple versions, there will be an 'Old Source Packages' link at the bottom of the landing page, e.g.,

  https://bioconductor.org/packages/3.6/bioc/html/edgeR.html

  https://bioconductor.org/packages/3.6/bioc/html/motifmatchr.html

To install a package from the Archive use biocLite():

​biocLite("https://bioconductor.org/packages/3.6/bioc/src/contrib/Archive/motifmatchr/motifmatchr_1.0.0.tar.gz")
