Groups.io: Changelog

CHANGE: On the pending message page, display the 'Ban Sender' even for existing members.
BUGFIX: For some reason, Google lost our geocode API key, which prevented the database map view from working. Had to recreate the key.
CHANGE: When rejecting a pending subscription by email, ignore the request if the subscription is not, in fact, pending (ie it's been approved already).
NEW: New group setting, Viruses, to set whether messages with viruses are blocked or moderated.
API: New group field: HandleVirus
CHANGE: Do not log a change in user or display name in the activity log of any group the user is banned from.
CHANGE: In activity log, change "Rejected message" to "Message rejected".
BUGFIX: Pending subscriptions older than two weeks were not being deleted.

NEW: If NormalizeHTMLEmails is set, normalize any added member signatures as well.
NEW: Added 'TR:' as a subject reply indicator.
CHANGE: Made our Message-ID header line parsing code smarter, to deal with a crazy message-id of the form "<salkdjjks@alksjdklas> (extra unexpected stuff here)"
CHANGE: Now removing any erroneous nulls from decoded message subject lines.
CHANGE: When exporting Yahoo Groups, scan messages for U+FFFD characters and remove them.
INTERNAL: Work on automated provisioning/configuration of new machines.
SYSADMIN: Created a new, larger search cluster, and reindexed the site.
BUGFIX: Added missing 'Reply To Group & Sender' option in full digests.
BUGFIX: When aliasing a hashtag to another tag, existing topics were not being properly updated in the search index. So searches on the aliased-to tag would not show the aliased-from topics. This was due to two issues in how we were updating the search index.

INTERNAL: Tested database backups.
INTERNAL: Changed the internals of the database APIs to better deal with the new connection pooling system.
CHANGE: Tweaked the wording of 'Default Post Policy' and 'Default group policy' to be more clear.
