Migration Information

This version removes support for direct "on radio" migration from versions before v2.6

This version of EdgeTX removes the ability to upgrade on-radio directly from OpenTX 2.3.15 or EdgeTX versions prior to 2.6 (which used the BIN format for storage of model and radio settings). It will however still be possible to migrate settings from older versions of OpenTX and EdgeTX via EdgeTX Companion. In some instances, particularly with some older OpenTX configurations, this is the more reliable mechanism for upgrading.

Highlights of this release include:

• LVGL re-write for the color screen interface is now complete. In doing so, there have been numerous improvements to the curves, special functions, logical switches and telemetry screens. Many thanks to @philmoz for doing a lot of the heavy lifting here.
  
• Various tabs can be turned on or off globally or on a per-model basis on both colorlcd and B&W radios. Have a helicopter that needs the heli tab, but don't want it showing on all your models? Or don't want to see it at all? The new "Enabled Features" button in the radio setup and model setup screens has got you covered! It looked like this during development.
  
• Numerous improvements to USB joystick support (allowing for greater control of how your radio controls are presented to the computer), as well as the ability to use your radio in conjunction to the radio simulator that is part of EdgeTX Companion.
  
• Support added for the Flysky FRM303 AFHDS3 RF module for some radios (NV14/EL18 native, TX16S with a mod, others to be documented). More information about the FRM303 here.
  
• Support added for the Multiplex MLink JR type module. See #3352 for more information.
  
• Numerous DSM telemetry fixes thanks to @frankiearzu via #3615, #3366, #3126 and #3690
  
• B&W screen radios: The time is now shown on the main screen between the horizontal trim sliders.
  
• B&W screen radios: Some of the longer and less commonly used sections in the model settings are now collapsed by default - i.e. timers, throttle settings, pre-flight checks, greatly reducing the amount of scrolling necessary.
  
• Support for Hebrew was added to radio firmware for color LCD radios and a voice pack is also available.
  
• If you have noise or buzzing when using high RF power outputs and no audio is playing, there is now a mute option for most radios - see #3703, #3710
  
• For those using the FrSky R9M 2019 in ACCESS mode in conjunction with the hardware mod, a separate firmware is no longer required. Simply choose the "External Module" option in Radio Settings -> Hardware against the relevant Serial / AUX port. #2562
  

More information with regards to changes, which is broken down into by screen type (Color LCD and B&W), is available in the user manual here.

Full Changelog: v2.8.5...v2.9.0

UI/UX behavioral changes and/or new capabilities:

• Prior to 2.9, when you connected the radio to the computer, two drives would be shown - a firmware drive, and the SD card. As of 2.9, only the SD card drive is shown, since updating the firmware via the firmware drive is extremely unreliable on Windows systems, and only leads to confusion.
  
• B&W screen radios with haptic vibration motors gave a momentary buzz when the power-on delay has completed. Color LCD radios now also do the same.
  
• Another layout was added for color radios - 4+2B right side 3QRT+1QRT by @daniel-snowsurf in #3315
  

Known Limitations and Issues

• Telemetry issue with FlySky FS-IA6B receivers: #3543
  
• External modules driven by PPM or S.BUS: incoming S.PORT telemetry is not processed anymore, as was the case with previous releases (see #3877).

I've now added a Summary of changes since v2.8 section at the bottom of the first post so that all information related to the EdgeTX v2.9 release is easily viewable in a single post.

Note that the SD Card Pack and Sound Pack have also been updated. Links to those are in the bullet-pointed list at the top of the first post.

I will likely wait a few weeks before updating my own transmitter while keeping an eye on the GitHub issues log during that time to see if anything of concern gets raised.
