Unison: download ældre versioner

Changes in 2.54.0
Released 2026-05-01
- Drop old wire protocol. Unison will no longer interoperate with
versions before 2.52.0 and will no longer read pre-2.52.0 archive
files.
- Document that LLM output is unwelcome in the Unison project (code,
issues, mailinglists, etc.).
- Add desktop file.
Deprecation warning: support for external rsync will be removed;
this may happen even in a micro release.
DEPRECATION MAY HAPPEN WITH LESS THAN TYPICAL NOTICE:
lablgtk is difficult to use safely, and future maintenance is
unclear. Implementing the GUI without lablgtk requires more effort
than seems likely to happen. Thus, it is possible that support for
the unison GUI may end suddenly, on a particular platform, or on all
platforms -- even in a micro release. See
#1075
MAINTENANCE WARNING: No one is contributing to verify that the Mac
GUI continues to work -- so it might not. (So far, there are no
reports of serious, frequent failures.)

Changes in 2.53.8
Released 2025-11-05
- Improve and simplify makefiles.
It is now possible to build with BSD make, Solaris/illumos make and
NMAKE, in addition to GNU Make. Building with MSVC is much simpler
now. The changes are larger than might be expected in a micro;
anyone building from source (or packaging) should consult
INSTALL.md for updated build instructions.
- Stop installing fsmonitor.py.
- Add ability to use reflinking instead of copying (if supported by
filesystem).
- Don't write fpcache if it is not necessary.
- Experimental default-off support to detect moves/renames and
rename on destination instead of copying (see -moves-experimental).
Deprecation warning: support for external rsync will be removed,
likely in 2.54.0.
