--------------------------
Setup:
* When upgrading from versions before v0.40, setup will now warn that ownCloud/Nextcloud data cannot be migrated rather than failing the installation.
Mail:
* An MTA-STS policy for incoming mail is now published (in DNS and over HTTPS) when the primary hostname and email address domain both have a signed TLS certificate installed, allowing senders to know that an encrypted connection should be enforced.
* The per-IP connection limit to the IMAP server has been doubled to allow more devices to connect at once, especially with multiple users behind a NAT.
DNS:
* autoconfig and autodiscover subdomains and CalDAV/CardDAV SRV records are no longer generated for domains that don't have user accounts since they are unnecessary.
* IPv6 addresses can now be specified for secondary DNS nameservers in the control panel.
TLS:
* TLS certificates are now provisioned in groups by parent domain to limit easy domain enumeration and make provisioning more resilient to errors for particular domains.
Control Panel:
* The control panel API is now fully documented at https://mailinabox.email/api-docs.html.
* User passwords can now have spaces.
* Status checks for automatic subdomains have been moved into the section for the parent domain.
* Typo fixed.
Web:
* The default web page served on fresh installations now adds the `noindex` meta tag.
* The HSTS header is revised to also be sent on non-success responses.
