We are pleased to offer the first release candidate for EdgeTX "Queen Anne's Revenge" v2.12.0.

Highlights of this release include:

Support for two new next gen STM32 H7 based radios, some tweaks for B&W radios, a lot of fixes and some new features for colorlcd radios, a lot of under the hood fixes and changes, improvements to flashing DFU/UF2 firmware in Companion. EdgeTX v2.12 is intended to be a stable firmware series for STM32 H7 radios which where added in 2.11 and the pre-release 3.0 which has been postponed as the new UI being worked on is not ready yet for prime time use, meaning no more "use the nightly version" or checking some manufacturer website to see if there are any updates. It is suitable for testing for anyone with a STM32F4 or STM32H7 handset - check this list if you are unsure which yours is.

Full Changelog: v2.11.4...v2.12.0-rc1

Known Limitations and Issues

• Wireless Model Trainer and CRSF/ELRS - if using the Multi Protocol Module (MPM) as a wireless trainer in conjunction with CRSF/ELRS, do not go above 250 Hz, otherwise the MPM wireless trainer will be dropped. 250 Hz or below is stable.
• Companion has had some substantial changes made to backend profile management and settings code via #6654 as well as a few other things in #6877 and #6892, so please ensure you double check everything is being read and written correctly when you first read and write profiles with this version of Companion, and generally when manipulating, copy and pasting models, etc, just in case anything snuck through.
• Please check TODO during the release candidate phase for any other release candidate specific issues and status of fixes.

UI/UX behavioral changes and/or new capabilities:

• quick/main menu looks slightly different, due to the reversion of the EdgeTX 3.0 UI
• quick/main menu is now themeable - you can configure the foreground (icon/label) and background colours (#6799)
• TODO

Supported radios

Language and Custom builds

Custom prebuilt firmware is no longer available. However, the CloudBuild option in EdgeTX is here to allow you to build your own firmware, with just a few clicks. Additionally, EdgeTX Companion now also has some support for CloudBuild, and will automatically fetch firmware for a supported language when you use the "Update components" option. But you can still build your own firmware online following this guide, request a specific build at TODO or ask on Discord for someone to build one for you.
