If you are using #Thunderbird with #GnuPG, see https://etaoinwu.com/en/blog/gpgme-2-workaround-for-thunderbird/ to make it work with the newer GpgME 2 stable releases and thus also with #Gpg4win 5.
Maybe our other hints and recommendations for https://wiki.gnupg.org/EMailClients/Thunderbird do interested you, too. ;-)
#GnuPG v2.5.24 has some security fixes, so #Gpg4win 5.1.1 is available for download as well.
Some support for RFC9980: "Post-Quantum Cryptography" is new, for those who need it because of governmental regulations. All others please stay on LibrePGP Kyber for some resistance against quantum computing based attacks.

(There was GnuPG 2.5.23 for a blink, but 2.5.24 fixed a regression. ;))
