## MDaemon 22.0.0 - May 17, 2022

### SPECIAL CONSIDERATIONS

[25771] 32-bit MDaemon has been discontinued. MDaemon 22.0 and newer will only be available in 64-bit. If you are currently running a 32-bit version on a supported 64-bit operation system, you can simply install the 64-bit version on top of the existing installation.

[23752] The minimum length for strong passwords must now be at least 8 characters. If your minimum length was set to fewer than 8 characters before updating to MDaemon 22, it will be changed to 8. The default minimum length for strong passwords on new installs is now 10.

[25215] MDaemon is moving away from using the terms "whitelist" and "blacklist". In many cases, they are now "allow list" and "block list". Features that had a "white list" to exempt IPs, addresses, etc., now have an "exempt list". The per-user spam filter contacts folders are now named "Allowed Senders" and "Blocked Senders". The folders for all accounts will be renamed when MDaemon 22 starts up for the first time.

                  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server
                      DisabledByDefault (DWORD) = 0
                      Enabled (DWORD) = 1

- [22820] Added an option at Accounts | Account Settings | Other | Passwords for strong passwords to require a special character (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~). It is enabled by default for new installs and disabled by default for existing installs.
