We are pleased to offer EdgeTX "Flying Dutchman" v2.8.0-RC2. As this is a release candidate, there may still be some minor issues that still need work on 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 fully bench-test your models after updating, and report any issues you encounter.

Full Changelog: https://github.com/EdgeTX/edgetx/compare/v2.8.0-rc1...v2.8.0-rc2

Highlights of this release include:

• Complete overhaul of UI framework for color screen radios (now implemented using LVGL). What does this mean for you? Many of the screens are now more optimised for use on a touch screen, work better with different screen orientations and sizes (i.e. the landscape RadioMaster TX16S vs portrait Flysky NV14), and reduce the amount of scrolling you need to do to find stuff. This includes most of the Radio Setup screens, and most of the Model Setup screens such as the first tab, Inputs tab, Mixes tab, Outputs tab and Flight Modes tab, as well as the edit screens for each of these. With the remainder to come in the next release. Check this video out to see what it looked like during development.
• New model select screen, and method of organising models. The new model labelling system is very powerful, as it allows you to add multiple labels to a single model - i.e. "Favorite" and "Plane", or "Helicopter" and "Flybarless". You can then filter the model list by any of these labels, or by any combination of them. This allows you to quickly find the model you want to fly, without having to scroll through a long list of models. It also removes another pain point - which is adding models to a transmitter - the new label system will auto-import any new models into the "Unlabeled" view, where you can then label them as you see fit. For users with a large number of models with model images it will open a lot faster, as it now loads images as you scroll through the list rather than all at once. For a look at what this looked like during development, see this video.
• When setting model/receiver IDs, the firmware will now tell you if the number is unique (not already used) or if it is in use by another model (and which!!) - and better than that, only IF it is using the same RF protocol (since you don't care about the ID of a model using a different protocol).
• Reduced the risk of corrupt radio.yml ruining your day by using a checksum to detect file corruption (i.e. due to faulty SD card, battery going flat in the middle of writing to the SD card). If the settings are corrupt, the radio will now warn you, automatically rename the file to radio_error.yml, and prompt you to recalibrate your analog inputs (sticks, 6POS, sliders, etc) so you have working settings. You can then examine the file later to find out what went wrong. If you want to manually edit the file, there is a new parameter at the top of the file (manuallyEdited) that you can change so the error check is skipped once (see #1481). Additionally, some radios (typically color screen radios) which were suffering from occasional extra long startup or SD card corruption should hopefully no longer do this (#2210).
• Lua API has been extended so it is possible to recreate the built-in widgets with Lua (#2279). Lua widgets can also override the built-in widgets (#2208). And they can be translated (#2275).
• On radios with software controllable power of the AUX1 and AUX2 serial UARTs, you can now turn the power on and off via the Radio Settings => Hardware tab (#1848).
• New special function for colorlcd that lets you set which main view screen is active
• Radio firmware now better indicates whether it is a nightly build, a pull request test build, or a self-compiled build, as viewable in the Radio Settings => Version tab (#1850).
• Lua Tools list in Radio/SYS menu sorted alphabetically also on B&W radios (#2258).
• Add acoustic and/or haptic feedback for touch events depending on radio settings (#2193). As well as more consistently for hard keys on colorlcd radios.
• More rotary encoder options for B&W radios. Allows for inversion of both vertical and horizontal UI movement (see #2045).
• Timers can now show time remaining or time elapsed (#2038), and voice announcements will change to minutes if the timer is longer than 10 minutes (#1891).
• Add channel outputs to logging (#2122).
• Color screen radios can also access the OneBit option potentially reducing the need to hardware mod your radio (#1994).
• Voice prompt when min and max trim reached (rather than just beeping) (#1955).
• ExpressLRS will soon support native baro/vario receivers - thus support for that telemetry was added (#2253)
• Support for 6D SpaceMouse serial module as an additional input for Horus-family radios (see #1853).

Companion:

• You can now check for (and download) updates for radio firmware, companion, multi-protocol module, SD card pack, sound pack and themes from within companion. (#2148, #2324).
• Clear the MODELS folder for B&W radios before adding new ones, so you won't see models in Companion and not on the radio or vice versa (#1932).
• Allow for opening individual model yaml files (#1959), and saving/exporting models to yaml files (#1968, #2296)
• Layout has been improved for showing plot points on Curves Tab (#1923).
• Can now save and load telemetry sensor values (#1954).
• GPS telemetry simulator added (#2125).
• Instead of overwriting a model when doing a copy and paste, Companion will now prompt on whether you want to insert, overwrite or cancel the action (#1976).

Radio/model specific changes:

• Jumper T16/T18: Allow for connection of a GPS if Bluetooth is not enabled (#1915)
• Jumper T16 / Frsky X12S: Community mods adding touch support using a Radiomaster TX16S touch panel (T16: #2060, X12S #1779)

New Radios

• BetaFPV LiteRadio3 Pro
• Flysky EL18 (preliminary)
• iFlight Commando 8
• RadioMaster TX12 Mark II

UI/UX behavioral changes and/or new capabilities:

• To access fullscreen mode now for widgets, with a touchscreen you long press on the widget to bring up the menu and choose "Fullscreen". For non-touch-screen, you long press ENT to enable widget selection mode, highlight the widget, and then press ENT to bring up the menu and choose "Fullscreen".
• Since you can now access top menu widget settings via a long press on touch screen radios, to access the main menu, the best places to touch are now the top left and right corners (i.e. the EdgeTX logo and the clock). If you don't have any widgets displayed in the top bar, or the main part of the screen, you can also tap there to bring up the main menu.
• Trainer TR1-TR16 entries will be hidden from inputs/mix source lists if the Trainer Mode is OFF (#2323).
• MULTI Trainer options won't be shown if you don't have a Multi-protocol module configured (#2299).

Known Limitations and Issues

• Known issues and resolutions will be tracked in #2447
