Starling 0.2 — early preview

Early preview build of the Starling desktop environment for Ubuntu 26.04 LTS, amd64.

# A Wayland-capable login manager is required; Ubuntu Desktop already has one.
sudo apt install gdm3

curl -fLO https://github.com/starling-build/starling/releases/download/v0.2/starling_0.2-1_amd64.deb
sudo apt install ./starling_0.2-1_amd64.deb

Then log out and pick Starling from the session menu at the login screen. See the User Guide and Installation Guide.

Includes security hardening for the session's control sockets (runtime dir 0700 + peer-uid checks) and fixes for four compositor use-after-frees reachable by Wayland clients. If you downloaded an earlier v0.2 build, please re-download.

This build installs on a clean machine, logs in through GDM, is seat-active, and passes the functional test suite against the packaged session.
