Per https://github.com/owncloud/core/issues/18224 and https://discourse.mailinabox.email/t/v13-upgrade-issue-with-calendar/757/10, upgrades from anything to ownCloud 8.1.1 were broken. But the workaround is to run the upgrade step twice.

* let munin choose what it wants to monitor, it may need an update periodically
* deactivate monitoring of NTP peers (this makes no sense)
* deactivate monitoring of network interfaces that aren't up (also makes no sense)
* we get errors in munin-node.log if we don't create /var/lib/munin-node/plugin-state/

v0.13 (August 19, 2015)
-----------------------

Mail:

* Outbound mail headers (the Recieved: header) are tweaked to possibly improve deliverability.
* Some MIME messages would hang Roundcube due to a missing package.
* The users permitted to send as an alias can now be different from where an alias forwards to.

DNS:

* The secondary nameservers option in the control panel now accepts more than one nameserver and a special xfr:IP format to specify zone-transfer-only IP addresses.
* A TLSA record is added for HTTPS for DNSSEC-aware clients that support it.

System:

* Backups can now be turned off, or stored in Amazon S3, through new control panel options.
* Munin was not working on machines confused about their hostname.
* ownCloud updated to version 8.1.1, its memcached caching enabled.
* When upgrading, network checks like blocked port 25 are now skipped.
* Tweaks to the intrusion detection rules for IMAP.
* Mail-in-a-Box's setup is a lot quieter, hiding lots of irrelevant messages.

Control panel:

* SSL certificate checks were failing on OVH/OpenVZ servers due to missing /dev/stdin.
* Improve the sort order of the domains in the status checks.
* Some links in the control panel were only working in Chrome.

automatic administrator aliases are probably not bidirectional because the administrator@ address is an alias and not a user

Querying dpkg for each package is slow, and we have way too much output on installation because of it.

fix problem with certificate verification on OpenVZ servers

bidirectional alias controls: a new permitted_senders column in the aliases table allows setting who can send as an address independently of where the address forwards to

But the default permitted senders are the same as the addresses the alias forwards to.

Merge branch 'dhpiggott-bidirectional-alias-controls'

Contacts and Calendar are now versioned separately from ownCloud core.

Contacts appears to be in a v0.4.x.x series. This is the hash of v0.4.0.0.

Per https://github.com/owncloud/calendar/issues/892, Calendar is in a 0.7.x series. This is the hash for 0.7.2.

Only core. The apps don't seem to have been updated.

S3 backups fail if no prefix is used

Merges branch 'ponychicken-backup'.

* going from s3 to file target wasn't working
* use 'local' in the config instead of a file: url, for the local target, so it is not path-specific
* break out the S3 fields since users can't be expected to know how to form a URL
* use boto to generate a list of S3 hosts
* use boto to validate that the user input for s3 is valid
* fix lots of html errors in the backup admin

Also clarify a comment and remove an unneeded type check
