 CHANGELOG
 =========
 
-To-be-released
---------------
+v0.07 (February 28, 2015)
+-------------------------
+
+Mail:
+
+* If the box manages mail for a domain and a subdomain of that domain, outbound mail from the subdomain was not DKIM-signed and would therefore fail DMARC tests on the receiving end, possibly result in the mail heading into spam folders.
+* Auto-configuration for Mozilla Thunderbird, Evolution, KMail, and Kontact is now available.
+* Domains that only have a catch-all alias or domain alias no longer automatically create/require admin@ and postmaster@ addresses since they'll forward anyway.
+* Roundcube is updated to version 1.1.0.
+* Authentication-Results headers for DMARC are now added to incoming mail.
+
+DNS:
+
+* If a custom CNAME record is set on a 'www' subdomain, the default A/AAAA records were preventing the CNAME from working.
+* If a custom DNS A record overrides one provided by the box, the a corresponding default IPv6 record by the box is removed since it will probably be incorrect.
+* Internationalized domain names (IDNs) are now supported for DNS and web, but email is not yet tested.
+
+Web:
+
+* Static websites now deny access to certain dot (.) files and directories which typically have sensitive info: .ht*, .svn*, .git*, .hg*, .bzr*.
+* The nginx server no longer reports its version and OS for better privacy.
+* The HTTP->HTTPS redirect is now more efficient.
+* When serving a 'www.' domain, reuse the SSL certificate for the parent domain if it covers the 'www' subdomain too
+* If a custom DNS CNAME record is set on a domain, don't offer to put a website on that domain. (Same logic already applies to custom A/AAAA records.)
+
+Control panel:
+
+* Status checks now check that system services are actually running by pinging each port that should have something running on it.
+* The status checks are now parallelized so they may be a little faster.
+* The status check for MX records now allow any priority, in case an unusual setup is required.
+* The interface for setting website domain-specific directories is simplified.
+* The mail guide now says that to use Outlook, Outlook 2007 or later on Windows 7 and later is required.
+* External DNS settings now skip the special "_secondary_nameserver" key which is used for storing secondary NS information.
+
+Setup:
+
+* Install cron if it isn't already installed.
+* Fix a units problem in the minimum memory check.
+* If you override the STORAGE_ROOT, your setting will now persist if you re-run setup.
+* Hangs due to apt wanting the user to resolve a conflict should now be fixed (apt will just clobber the problematic file now).
+
+v0.06 (January 4, 2015)
+-----------------------
+
+Mail:
+
+* Set better default system limits to accommodate boxes handling mail for 20+ users.
+
+Contacts/calendar:
+
+* Update to ownCloud to 7.0.4.
+* Contacts syncing via ActiveSync wasn't working.
+
+Control panel:
+
+* New control panel for setting custom DNS settings (without having to use the API).
+* Status checks showed a false positive for Spamhause blacklists and for secondary DNS in some cases.
+* Status checks would fail to load if openssh-sever was not pre-installed, but openssh-server is not required.
+* The local DNS cache is cleared before running the status checks using 'rncd' now rather than restarting 'bind9', which should be faster and wont interrupt other services.
+* Multi-domain and wildcard certificate can now be installed through the control panel.
+* The DNS API now allows the setting of SRV records.
+
+Misc:
+
+* IPv6 configuration error in postgrey, nginx.
+* Missing dependency on sudo.
+
+v0.05 (November 18, 2014)
+-------------------------
+
+Mail:
+
+* The maximum size of outbound mail sent via webmail and Exchange/ActiveSync has been increased to 128 MB, the same as when using SMTP.
+* Spam is no longer wrapped as an attachment inside a scary Spamassassin explanation. The original message is simply moved straight to the Spam folder unchanged.
+* There is a new iOS/Mac OS X Configuration Profile link in the control panel which makes it easier to configure IMAP/SMTP/CalDAV/CardDAV on iOS devices and Macs.
+* "Domain aliases" can now be configured in the control panel.
+* Updated to [Roundcube 1.0.3](http://trac.roundcube.net/wiki/Changelog).
+* IMAP/SMTP is now recommended even on iOS devices as Exchange/ActiveSync is terribly buggy.
+
+Control panel:
+
+* Installing an SSL certificate for the primary hostname would cause problems until a restart (services needed to be restarted).
+* Installing SSL certificates would fail if /tmp was on a different filesystem.
+* Better error messages when installing a SSL certificate fails.
+* The local DNS cache is now cleared each time the system status checks are run.
+* Documented how to use +tag addressing.
+* Minor UI tweaks.
+
+Other:
+
+* Updated to [ownCloud 7.0.3](http://owncloud.org/changelog/).
+* The ownCloud API is now exposed properly.
+* DNSSEC now works on `.guide` domains now too (RSASHA256).
+
+v0.04 (October 15, 2014)
+------------------------
 
 Breaking changes:
 
@@ -31,6 +125,7 @@ Security:
 
 Other:
 
+* Spam filter learning by dragging mail in and out of the Spam folder should hopefully be working now.
 * Some things were broken if the machine had an IPv6 address.
 * Other things were broken if the machine was on a non-utf8 locale.
 * No longer implementing webfinger.
