EDIT (2nd September 2023): The final release of EdgeTX v2.9.0 is now available. See another thread HERE for details.

The EdgeTX v2.9.0-RC2 ("Providence") was released a few days ago. As with any release candidate version of software, there will still be bugs present in this pre-release version, so if you decide to use it make sure you know the risks and do so with caution. Details and links are below.

Quote:We are pleased to offer EdgeTX "Providence" v2.9.0-RC2. As this is a release candidate, there may still be some minor issues that still need work before release. We need your help in testing these builds to ensure there are no major bugs or faults that will cause problems during flight. Please ensure you back up your model and radio settings before updating, fully bench-test your models after updating, and report any issues you encounter.

Migration Information

Reminder: v2.9 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.

What's Changed since 2.9.0-RC1

Features:

• Companion: Warn if radio settings version not supported (e.g. when using a older version of Companion with newer firmware) (#3766)
  
• B&W: Change layout of telemetry page on B&W radios to match color layout (#3770)
  
• B&W: Auto expand sensor list when discovering sensors (#3828)
  
• Add SF to mute audio amplifier on supported radios (#3774)
  

Fixes:

• Prevent functional degradation if SD has less than 50MB free space (#3730)
  
• dbm unit not being played when playing telemetry values 69e9bcd
  
• Don't override configured SD Logs value when opening edit screen (#3755)
  
• Reset proto scan software timer to MULTI_PROTOLIST_START_TIMEOUT (#3763)
  
• Bluetooth detection for X7S (#3754)
  
• fix(AFHDS3): iBus IN and Failsafe settings not updating (#3793)
  
• fix(color): When in screen settings, ignore SYS/MDL, treat TELE as RTN (preventing possible EM) (#3845)
  
• fix(color): Use ACTIVE theme color for inputs, mixes, LS, GV and SF (like 2.7x) (#3897)
  
• feat(bw128): Swap modelname telemetry screen topbar for timer1 if defined (#3856)
  
• fix(bw): Remaining/elapsed display on telemetry screen topbar (#3871)
  
• fix: Some AFHDS2A/AFHDS3 GPS/ALT telemetry handling issues (#3582)
  
• Companion: Do not display setup center beep option for multipos (#3744)
  
• Companion: Reduce curve name length to match firmware (#3825)
  
• Companion: Disable backup and restore for all radios (#3824)
  
• compilation: GVARS=NO error (#3769), trace flooding calls (#3767)
  

Full Changelog: v2.8.5...v2.9.0-rc2

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 lead 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.
  
• On B&W screen radios, several longer categories are now collapable, and are collapsed by default. For instance, timers now only occupy one line each.
  
• It is now possible to disable or enable several model setup tabs, as well as some radio setup tabs, either globally (in radio setup), or on a per-model basis (in model setup), through the use of the "Enabled Features" option. i.e. Have a heli, but don't want the heli tab for every model? Disable it globally, and then enable it just for the model you want it for. Don't use GVs or Trainer? Just turn those tabs off!
  
• Another layout was added for color radios - 4+2B right side 3QRT+1QRT by @daniel-snowsurf in #3315
  

Known Limitations and Issues:

• EL18: No Companion support yet
  
• 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.
  
• Lua setSerialBaudrate is currently non-functional
