I've sent a longish post to the R-devel mailing list with this
topic here:
https://stat.ethz.ch/pipermail/r-devel/2023-September/082892.html
In the mean time, the plan is to effectuate the change in
R-devel (the in-development version of R) on Sep.28, ~ 9:30 CEST ( =UTC+2)
AFAIK, this will only affect bioconductor packages *after* the
upcoming release of BioC ... when they will all begin to run /
be tested "against R-devel".
But if you use CI / R-bug / rocker / ... tests for your packages
using the development version of R, this may affect some of
your bioconductor packages already sooner.
Best regards,
Martin
