Test Plan

poudriere testport - OK

Whoa. Lots of rather significant changes for what the version number says is just a patch update.

The ABI version on libguac.so.12 has been incremented, which means that any port that depends
on this and that contains applications that link against that shlib will need a port revision bump.
Which looks like maybe only net/guacamole-client ? Need to confirm that.

As this is an official Apache Incubator project now, update the WWW: line in pkg-descr to

https://guacamole.incubator.apache.org/

and consider switching the GitHub project to https://github.com/apache/incubator-guacamole-server ?

Also see PR215802 -- technically this port will need a portrevision bump because of the change in ABI
version of a shlib it depends on. And that PORTREVISION bump will need MFH'ing as it's a security fix to libvncserver. Would be handy to commit the libvncserver update before committing the update to
guacamole-server.

Done.

Client update depends on this in Bugzilla. I was still testing it, so review is coming up.
