Hi folks, As expected of a new major release of R, there is a break in compatibility for R packages. From the NEWS entry for 4.0.0: Packages need to be (re-)installed under this version (4.0.0) of R. This has two impacts on Fedora/EPEL. 1. Users who update to 4.0.0 will need to rebuild any/all packages installed from CRAN. 2. Fedora/EPEL R packages will need to be rebuilt for 4.0.0. For EPEL, #2 is less impactful (there are not that many R packages in EPEL) but for Fedora, this is a pretty big lift. I'm thinking that we'll only push this update to EPEL-8, F32, and rawhide, but please, if you have input here, chime in. Thanks, Tom [[alternative HTML version deleted]]

And we patched the symbol issues in v3.6.3 in F31 (please, don't forget to trigger a build and an update) thanks to Paul Murrell, so we're fine on that front. I'll have to rebuild 15k packages on the CRAN Copr repo. That's gonna be huuuge. :) I'll try to do that while the update is sitting in updates-testing and before it's pushed to stable. I?aki
Thinking out loud here... do we want to have some macro magic to embed a dependency on an R(ABI) provides? Where R 4.0.0 would provide R(ABI) = 4 and all R packages built against it would pick up Requires: R(ABI) = 4 ? I don't suppose we need it, since the likelihood of someone installing R module packages but not updating R is low, but I wanted to throw it out there.
