- Pin the Codex model (gpt-5.5) so a retired binary default can't 400 users
  out of every generative feature; dedicated "update the app" banner.
- Fail-fast error handling: no more infinite retry loops on rate limits;
  every surface stops cleanly and offers a manual retry.
- Linux x64 (AppImage) as a first-class build target.
- Anonymous open/update analytics ping (opt-out via GETIT_DISABLE_ANALYTICS)

- Open source: CONTRIBUTING guide + Discord community; team LinkedIn links.

v1.1.1

Wizard fixes from the v1.1.0 Windows VM test:

  Microsoft VC++ Redistributable install.

v1.1.0

Re-cut with the packaged-build fixes: ad-hoc mac signing, Turbopack
externals restored in the packaged tree, NSIS no longer over-mmap on
Windows, wizard simplified to a single sign-in step on the happy path
(bundled Codex CLI trusted at build-time version).
