Keychron Q6 Ultra 8K (ANSI) — Firmware Changelog & Download Archive (unofficial)

Keychron does not publish release notes for the Keychron Q6 Ultra 8K, so this is a community-maintained changelog and download index for its firmware. Updates are normally delivered silently through the web configurator at launcher.keychron.com (ZMK-based board — no QMK Toolbox flashing).

⚠️ Unofficial. The per-version "changes" below are inferred from analysis of the firmware images (Keychron ships no notes); treat them as best-effort. Keychron's own advice: if your keyboard works fine, you don't need to update — updates can occasionally fail/brick a board.

Firmware API (for reference)

The launcher fetches firmware metadata from these public endpoints (vpId = 875827808 for this board):

• Latest firmware: GET https://launcher.keychron.com/vapi/v2/product/875827808
• Full version history: GET https://launcher.keychron.com/vapi/v2/firmware/875827808 → returns every version + download path.

The release-notes field (languageDesc) is returned empty for this model, which is why no official changelog exists — hence this document.
