Thanks Andrey, that is good to know. The Qt5 version under MacOS
crashed rapidly after start-up until several months ago when a few
nasty bugs were corrected. We will need to do more testing and
adjust our build-process, but what you say makes it plausible that
the move to Qt5 could happen sooner than I feared.

The point with Guile 2 is that it basically has nothing to do with Guile 1,
so the most of the interface has to be rewritten and retested.
At a first stage, we plan to run Guile 2 in interpreter mode.
This causes a slow-down with respect to Guile 1, but it will at least
enable us to track down potential problems. During a second stage,
we should move to the compiled version, but this will again require
a lot of work and testing.

This is probably correct for Linux developers, but less so for
ordinary users. In the cases of Debian and Ubuntu, we have also
set up a TeXmacs repo that can be added in order to manage TeXmacs
in the usual way (and automatically get updates).
