 CHANGELOG
 =========
 
+In Development
+--------------
+
+* Incoming emails with SPF/DKIM/DMARC failures now have a higher spam score, and these messages are more likely to appear in the junk folder, since they are often spam/phishing.
+* A new Download button in the control panel's External DNS page can be used to download the required DNS records in zonefile format.
+* Blackblaze is now a supported backup protocol.
+* Fixed the problem when the control panel would report DNS entries as Not Set by increasing a bind query limit.
+* Fixed a control panel startup bug on some systems.
+* Fixed the MTA-STS policy file's line endings.
+* Nextcloud's photos, dashboard, and activity apps are disabled since we only support contacts and calendar.
