Off-the-Record Messaging

The functionality of the OTR button has now moved
to a menu. The button can optionally be shown in
addition, but now in the conversation toolbar. New
icons were added. Buddy authentication has been
revamped, based on the user study published in
SOUPS 2008. The default is now to choose a
question and an answer only you and the buddy
should know. The question is displayed to the
buddy, who is prompted for the answer. The "shared
secret" and "fingerprint" authentication methods
are still available. Translations were made for
Arabic, German, Russian, and Hungarian.

Support for pidgin 2.x, new translations for English, Dutch, Spanish, French, and Slovak, a new option to not log OTR conversations, transparent fragmentation of large messages, and replacement of the "view secure session id" and "verify fingerprint" options from the OTR button menu with an "authenticate buddy" option. This new option allows you to authenticate your buddies by entering some secret that only the two of you know rather than by using a long, user-unfriendly sequence of hex characters.

Support for OTR protocol version 2 was added. It
will still interoperate with version 1 clients,
though with a warning to the user. The OTR button
now has a right-click context menu with some
useful options. The OTR button now has icons in
addition to text to indicate the state of a
conversation. Most popups have been changed to
inline messages in the conversation window.

A fix to co-exist more nicely with other encrypting Gaim plugins. gaim-otr is now autoconfiscated.

This release adds default and per-buddy policy selection:
never use OTR, OTR only if manually requested,
automatically start OTR if possible, or refuse to not use OTR.
It now resends the last message if it caused a re-keying.
OTR
control messages are no longer displayed as if they were
received as IM messages. There is a new multi-page UI.
Users can send a
control message to a buddy if a private
conversation is terminated. It now removes people without
fingerprints from the Known Fingerprints list. The column
heads in the Known Fingerprints list now sort properly.
