Thanks @jeroen. After our chat yesterday, I think the "minimal disruption,
maximal support" version of this plus #50612 will need us to make these changes:
- build with RTools45 as the default on normal (per-PR) CI instead of the
current RTools40
- nightlies - update the r-binary-packages job to include:
- Rtools45 x86_64
- Rtools45 aarch64 (on a `windows-11-arm` runner)
- Rtools40 x86_64
- a test job on R 4.2 using the Rtools40 zip
- a test job on R release on arm64 using the aarch64 zip
- binaries: in addition to Rtools40 x86_64, we also distribute Rtools45
x86_64 and Rtools45 aarch64 (also will need to update the logic which
determines which binary to select)
This allows us to keep supporting R versions back to 4.2 on Windows. We
don't want to upgrade RTools from 40 to 42, because there was a move from msys2
to MXE there which ended up with older versions of OpenSSL and curl.
@nealrichardson or @jonkeane - before I make a start on this, how does this
sound?
