Query regarding "Kerberos 5 Release 1.20/1.21"

[Kumar, Gaurav]

Hi Team,
We are planning to upgrade OpenSSL to 3.x version. According to  https://web.mit.edu/kerberos/krb5-1.20/README-1.20.txt, major changes are done in krb5-1.20 and it is compatible with OpenSSL 3.x.
Does krb5-1.20/1.21 support IBM AIX ( as we faced issues with AIX in the past) ?
If not supported,

  *   Is there any plan to support IBM AIX ?
  *    Is there any limitation in IBM AIX by which it was not supported ?

Thanks,
Gaurav
