[Galene] ANNOUNCE: galene-0.6

[Juliusz Chroboczek <jch@irif.fr>]

Dear all,

Galene 0.6 is available by doing

  git clone -b galene-0.6 https://github.com/jech/galene

For more information about the Galene videoconference server, please see

This version contains a number of protocol changes that are intended to
make it easier to write native (non-web) clients.  In particular, the
protocol now carries an explicit version number, so you should get
a useful error message in case the client and the server mismatch.

10 September 2022: Galene 0.6

  * Version the protocol: the handshake message now contains a version
    number, and the server will warn if it is incorrect.  This will become
    a hard error in the future.
  * Rework the peer-to-peer file transfer protocol.  It now lives in
    protocol.js, which makes it easy to use by third-party clients.
  * Extend the authorization protocol to allow the authorization server to
    request that the client fall back to password authorization.
  * Make it possible to run the web server on a Unix domain socket.
    Thanks to Martin Pépin.
  * Check that a given group exists before redirecting from the landing
    page.  This avoids an unsightly 404 error when the user makes a typo.
  * Publish the group name and websocket endpoint in the group status.
    This avoids hardwiring the server structure in the client.
  * Fix a race condition that could cause chathistory messages to be sent
    before the joined status.
