When an update to a package happens, the old version is supposed to be in e.g. https://bioconductor.org/packages/3.14/bioc/src/contrib/Archive/ (see Bioconductor Package Archives )
That URL workes for 3.15: https://bioconductor.org/packages/3.15/bioc/src/contrib/Archive/ but 404s for older versions (I tested 3.6, 3.8, 3.14).
I suppose there was a data migration that neglected them?.
Can we get them back in the name of reproducibility?
Some of the mirrors still have the files, https://bioconductor.statistik.tu-dortmund.de/packages/3.14/bioc/src/contrib/Archive/
Unfortunately, they did not preserve the date-of-release (or retirement, actually) meta data.
You know what, the files actually are still there, apparently, but the listing fails for any but the newest bioconductor.
Y'all have now also lost the 3.16 archives.
That meta information is crucial to be able to reproduce a bioconductor release as it was on release day...
