ESP32 V3.0.0 doesn't support LCD8, LCD16 and RGBPanel anymore - what can i do now?

[hape65]

the problem is this:
i own a ESP32-S3 with a display on it (JC8048W550). In the ESP32 V2.0.x i used the RGBPanel function everything works. Now i have a ESP32-C6 and installed V3.0.0 because that is the only version which includes ESP32-C6. If i now try to compile the old program for the
ESP32-S3 there are many errors because RGBPanel is no longer supported by Espressif.

Arduino_ESP32RGBPanel *rgbpanel = new Arduino_ESP32RGBPanel(
^~~~~~~~~~~~~~~~~~~~~
Arduino_ESP32SPIDMA
Arduino_GFX_dev_device.h:185:1: error: 'Arduino_RGB_Display' does not name a type

Why is that no longer supported because now V2.0.x is incompatible with V3.0.0 .
Why ost this really a pain? If iwant to compile with Arduino 2.3.2 i have to choose ESP V2.0.x for ESP32-S3 and than change it to ESP V3.0.0 if i want to compile with ESP32-C6. All precompiled librarys are gone after i change this and the compile needs more than 15 minutes to end! There is no way to install 2 versions of Arduino.
I don't really understand why this was done (eliminate the LCD8, LCD16, RGBPanle functionallity).
Any explanation or idea to get around this problem with V3.0.0 would be very appriciated.

3.0.0 was a major version change with major changes in the underlying framework. That means there were breaking changes in the APIs. The author (Adafruit) of the 3rd party library will need to update their code to support it. You have not told us which library you are including, but you can open an issue on their github repository so they can update it to work on the new version.
