[OTR-announce] pidgin-otr and libotr 4.0.0 released!

[Ian Goldberg]

We are pleased to announce the official release of version 4.0.0
of our OTR software:

* the pidgin-otr plugin for the Pidgin instant messaging client
* the libotr library for integrating OTR support into your own applications

As always, you can find the new software at http://otr.cypherpunks.ca/

The Windows installer for pidgin-otr 4.0.0 is:

http://www.cypherpunks.ca/otr/binaries/windows/pidgin-otr-4.0.0-0.exe

gpg signature:
http://www.cypherpunks.ca/otr/binaries/windows/pidgin-otr-4.0.0-0.exe.asc

The main new features in 4.0.0:

* Support v3 of the OTR protocol

* The plugin now supports multiple OTR conversations with the same buddy
  who is logged in at multiple locations. In this case, a new OTR menu
  will appear, which allows you to select which session an outgoing
  message is indended for. Note that concurrent SMP authentications with
  the same buddy who is logged in multiple times is not yet supported
  (starting a second authentication will end the first).

* During a private conversation with a buddy, an incoming unencrypted
  message will now trigger the regular incoming message notifications.
  In Pidgin this includes showing the message in the top-right
  notification area, if it is normally configured to do so.

* When a private conversation begins, the plugin will indicate whether
  Pidgin is configured to log the conversation.

* By default, OTR conversations will not be logged by Pidgin.

* New translations.

* libotr API changes:

  - instance tags, to support multiple simultaneous logins

  - support for asynchronous private key generation

  - the ability to provide an "extra" symmetric key to applications
    (with forward secrecy)

  - applications can supply a formation conversion callback if they do
    not natively use XHTML-style UTF8 markup

  - error messages formerly provided by libotr are now handled using
    callbacks to the application, for better i18n support

  - otrl_message_sending now handles message fragmentation internally


Enjoy the new software!
