v1.5.1

XeFM 1.5.1

• The macOS app runs on macOS 26 again — 1.5.0 was built on a Mac running
  macOS 27 and would not start on anything older, showing "You can't use this
  version of the application with this version of macOS". The version the app
  requires is now something the build decides on purpose, instead of whatever
  the machine that produced the release happened to be running.

Also: the DMG reports the macOS version it actually needs rather than a
long-stale 10.13, and the download table in the desktop guide says the same.
Nothing here affects Windows, so this release ships no Windows build — the
1.5.0 zip and the
Microsoft Store package
remain current.
