[PROJ] PROJ 9.8.1 release candidate and motion to approve it

[Kristian Evers]

Howard,

I don't think we will gain anything by lagging behind by x months of EPSG releases. No one else is testing their releases in real time (as far as I know), so we would just find the same issues at a later date.

I think our best chance for now is to improve testing on our side as much as possible, as well as providing the means for non-techy geodesist to tests stuff in development. The first part I think we can start acting on right away, and perhaps even coordinate with the EPSG folks somehow. The second part would require pre-release binaries to be easy to access, as I don't think we can expect that geodesy experts are able to compile PROJ from source. This meshes well with previous talks on automating the release process.
