OpenVPN 2.5 - digest invalid with 'auth sha512'

We detected an issue breaking backward-compatibility.
If I use in a config "auth sha512", OpenVPN 2.4 accepts it, OpenVPN 3 accepts it, OpenVPN 2.5 does not.
I understand the syntax must be uppercase ("auth SHA512"), but
OVPN files around the world, if using the lowercase syntax, will stop working (digest invalid)
and I think a force uppercase in options parsing in OpenVPN codebase will be a clean solution to avoid troubles.

Can someone fill a bug report to understand at least if this will be considered? Thanks.

Note: Oracle here: ... names.html
explicit write "Algorithm names are not case-sensitive".

All digest-algorithm values are case-insensitive.
so i think this issue can be classified as bug.
