Overview

Big update for FreeRTOS users who don't need LWIP, because it now should not link in LWIP code or allocate LWIP memory unless your code actually does do LWIP calls. RP2350 PSRAM timing code has been updated to work better with overclocked devices (useful for the Adafruit libraries). Bidirectional I2S (INPUT_PULLUP) now outputs on the proper edge fixing setup/hold timing issues.
