Month: 2025-09. Highlights: Delivered a critical fix to ensure correct color rendering on Waveshare LCDs for ESP32-S3-TOUCH-LCD devices by forcing color_order to RGB on affected models (4.3 and 7-800X480). This addressed a long-standing display configuration issue and was implemented via two commits under issue #10835. Major bug fixed: incorrect color output due to misconfigured color_order, now consistently RGB across the supported Waveshare displays.
