version 0.9 (unreleased) - rails 4, twitter feed and deprecations
----------------------------------------------------

We have a great contribution from the Rails Girls Summer of Code again!
The landing page of the webapp can now include a twitter feed to display
news from the provider.
Other than that this is a maintainance and transition release.

* Twitter feed on main page (thanks theaamanda and lilaluca).
* upgrade to rails 4.2

Upgrading:

* We now use rails 4's `secret_key_base`. Please make sure to supply it
  in config/config.yml for production environments. If you are using the
  leap platform that will already take care of it.


version 0.8 - email and RGSoC
------------------------------------------

This release focused on getting all the features needed for a complete
email provider and merging in the work done by Rails Girls Summer of
Code.

* Support for invite codes: admins can require that new
  users present an invite code. If required, the invite code
  cannot be bypassed and is incorporated in the Secure Remote
  Password negotiation. (thanks ankonym, ayajaff).
* Support for customer account billing, including subscriptions.
  (thanks claucece, EvyW).
* Ability to remove, disable, and re-enable users.
  (thanks EvyW).
* Many localization fixes.
* Many bug fixes.

version 0.7.1 - localization
------------------------------------------

Support for localization has been turned on and much improved. Since you
probably don't want to enable all the available languages, make sure to set
`default_locale` and `available_locales` in your configuration file.

When deploying via the LEAP platform, these are controlled via
`default_locale` and `languages` in provider.json.

version 0.7 - rotating DBs
------------------------------------------

CouchDB is not designed to handle ephemeral data, like sessions, because
documents are never really deleted (a tombstone document is always kept to
record the deletion). To overcome this limitation, we now rotate the
`sessions` and `tokens` databases monthly. The new database names are
`tokens_XXX` and `sessions_XXX` where XXX is a counter since the epoch that
increments every month (not a calendar month, but a month's worth of seconds).
Additionally, nagios checks and `leap test run` now will create and destroy
test users in the `tmp_users` database, which will get periodically deleted
and recreated.
