The tarball is signed and you can get the PGP signature at
https://alpha.gnu ... e-4.90.tar.gz.sig

The planned date for releasing 5.0 is Sunday 15 August 2026, but
this may change depending on the amount of problems found in this
pre-release, and the subsequent needed additional pre-releases.

Please report any problem found with the pre-release, comments or

In behalf of the poke developers, thank you!
