Ubuntu Rev-6.1 — October 19, 2026

Centered PocketFab logo and product title, with Rev-6.1 underneath.
Removed development banners and beta footer from the application window.
Includes the accepted microphone self-test, dependency reporting and keyring fix.
Two-way Windows/Ubuntu call audio confirmed by the user on pocketfab4090.
The native executable is unchanged from the accepted build.

Packaging checks do not establish fresh-machine activation or live-call
acceptance on other machines. The new installer requires an Ubuntu installation
check before website publication. No website or release-feed change is included.
