---------------------------
* [DEPRECATION] As of this release, the previous implementation that
relied on the Guacamole Tomcat servlet is deprecated. A `stable-4.1`
branch exists that might still receive bugfixes for some time, but
do not count on this being supported any longer than the lifetime of
the Open edX Koa release. The [Ansible
playbooks](https://github.com/hastexo/edx-configuration/tree/hastexo/juniper/hastexo_xblock)
that tie into `edx-configuration` have been updated to “do the right
thing” based on the hastexo XBlock version being deployed: for
version 5 and up, they deploy Daphne and pyguacamole; for earlier
versions, they continue to deploy Tomcat and the Guacamole servlet.
