Dear all,

Galène 0.2 is now available:

  git clone -b galene-0.2 https://github.com/jech/galene

For more information about the Galène videoconference server, please see

  https://galene.org

The main reason for releasing this version is that it works around an
issue that would cause Galène to fail on 32-bit architectures such as
ARMv7, and an issue that would cause saving to disk to fail on Windows.
There are also a number of new features and refinements, please see the
attached list of changes.

Enjoy,

-- Juliusz Chroboczek

9 January 2021: Galène 0.2

  * We now work around a limitation of the Go runtime that used to cause
    a crash on 32-bit architectures.
  * Recording to disk now works on Windows too.
  * Error handling has been improved.  In particular, group operators now
    receive a friendly warning when recording to disk fails for some reason.
  * It is now possible to configure a group to use codecs such as VP9 and
    H.264.  The default is still to use VP8 and Opus, as this yields the
    best compatibility across browsers.  Only VP8, VP9 and Opus can be
    saved to disk.
  * The command-line option "-relay-only" can be used to specify that all
    media traffic should go through a TURN server.
  * It is now possible to generate TURN passwords automatically, which
    avoids leaking long-term TURN credentials.  See the "credentialType"
    value "hmac-sha1" described in README.
  * The ICE configuration will now be checked periodically, and new
    clients will use an updated configuration.
  * The client-server protocol has been reworked to be more symmetric
    and more secure.  It is now documented in the file README.PROTOCOL.
  * The stream abort protocol message is now supported in the client->server
    direction, making it possible for the client to reject a stream.
  * The delay before sending NACKs has been reduced, which gives a major
    boost in video quality.
  * The play from disk button is not available when the browser doesn't
    support the required API.  We used to display a cryptic error message
    in that case.
  * The command-line option -insecure allows using plain HTTP, which is
    useful when running behind a reverse proxy.
  * When saving to disk to disk, the keyframe interval has been reduced to 4s.
  * We now send keepalives after 55s at most, which should fix issues with
    reverse proxies timing out the WebSocket.
