We are pleased to offer EdgeTX "Queen Anne's Revenge" v2.12.0. Thank you for all the feedback and testing by you, the community (and partner manufacturers) which has allowed us to identify and squash both new and old bugs!! We simply cannot have done this without you! 🤗 🍻

Highlights of this release include:

Support for several next gen STM32 H7 based radios. B&W screen radios get a model quick select option and source options for mixes are consistent with their color screen counterparts. Color screen radios get theme control of the quick menu, QR GPS code locator tool and a few more screen layout options. There are a lot of under the hood fixes and changes, as well as STM32F4 radios being generally faster to start than in 2.11. Companion has improvements to firmware flashing generally (in addition to the necessary added support for UF2 files), can download and install the ExpressLRS Lua tool as part of update checks, will preserve your calibration settings when writing old model and radio settings to the handset, and will also ensure your model notes are stored in your .etx file.

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. This is so you no longer have to use the nightly version or checking some manufacturer website to see if there are any updates. While the focus is for STM32H7 radios, it is suitable for anyone with a STM32F4 or STM32H7 handset (with one exception - the PA01 - there are some outstanding issues for this handset still which makes 2.11 the better choice for now).

Full Changelog: v2.11.5...v2.12.0

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.

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)
• model notes, when present, are shown as a tab in the model setup area
• heli options, when enabled, are shown as a button at the bottom of the model setup page rather than as a tab
• STM32F4: the UART speed for external CRSF modules has been limited to 3.75Mbps due to recommendation of the ExpressLRS developers (#6923)

Flash firmware via Chrome based browser

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.
