2. New board setup files have been added for the Seeed XIAO with round display, LilyGo T-Embed S3, LilyGo_T_QT_Pro_S3, ESP32 S3 Box and ESP32_S3_Box_Lite. The "RPi" interface style boards are now supported with the ESP32 S3.

3. New functions have been added to draw smooth (antialiased) arcs, circles, and rounded rectangle outlines. New sketches are provided in the "Smooth Graphics" examples folder. Arcs can be drawn with or without anti-aliasing (which will then render faster). The arc ends can be straight or rounded. The arc drawing algorithm uses an optimised fixed point sqrt() function to improve performance on processors that do not have a hardware Floating Point Unit (e.g. RP2040). Here are two demo images, on the left smooth (anti-aliased) arcs with rounded ends, the image to the right is the same resolution (grabbed from the same 240x240 TFT) with the smoothing diasbled (no anti-aliasing):
