Apparently the version of AnnotationDbi packages in the Bioconductor 3.9 release was bumped recently.
It was 1.46.0 before, now it's at 1.46.1 (see https://bioconductor.org/packages/3.9/bioc/html/AnnotationDbi.html).
This is usually not a problem since package versions that were once included in a Bioconductor release are usually still available for download via the archive since recently (see https://support.bioconductor.org/p/102555/).
However, in this case there simply is no AnnotationDbi listed at http://bioconductor.org/packages/3.9/bioc/src/contrib/Archive/, so the source tarball for AnnotationDbi 1.46.0 is no longer available.
Is there a specific reason for this, or can this be fixed?
(related: https://bioconductor.org/packages/3.9/bioc/news/AnnotationDbi/NEWS is horribly outdated, is there an overview of changes for recent versions available somewhere?)
