[Bioc-devel] R-devel for Windows: Rtools3.5 vs Rtools4.0

The Bioconductor 3.11 builds transitioned in the last week to using the new tool chain, following CRAN's lead.

As a sanity check (ours!) what makes you say

    It appears that the Bioconductor developmental repository is using rtools35

    Dear Biocore team,
    
    How is Bioconductor handling the transition to the new R for Windows toolchain?
    
    The R-Devel build for Windows currently available from CRAN uses Jerome Oom's new gcc 8.3.0 toolchain from rtools40, whereas R-Devel builds for Windows downloaded from CRAN a couple of months ago used the older rtool35 toolchain.
    
    It appears that the Bioconductor developmental repository is using rtools35, which means that BiocManager::install is incompatible with the R-Devel build for Windows now on CRAN but works with R-Devel from a month or two ago.
    
    When Bioconductor 3.11 is released, will it be the rtools40 toolchain or rtools35?
    
    Thanks
    Gordon
