  • Smaller builds: memory and flash regressions since 3.10.3 cut back (#4801)
    • Code that a sketch can never use is no longer linked in: the FLEX_IO clockless pipeline in SPI-only sketches, the I2S clockless peripheral on esp32dev, the ADC driver unless fl::analogRead is used, the task Scheduler in driver wait loops (new fl::task::yield_system()), RGBW/RGBWW conversion in RGB-only sketches, and libstdc++ locale init.
    • Wi-Fi is detected through esp_netif, so ESP32 sketches without networking drop 1.3 KB of Wi-Fi RAM.
    • Teensy I2S audio-input buffers are allocated on first use (−1 KB RAM in LED-only sketches).
    • Uno Blink static RAM is down to 118 B, below 3.10.3.
    • Dashboard deltas vs 3.10.6-era master: esp32dev Blink −5.2 KB flash / −1.9 KB RAM, esp32dev APA102 −15.9 KB / −2.2 KB, esp32s3 Blink −9.2 KB / −0.7 KB, esp32s3 APA102 −16.6 KB / −0.7 KB.
  • Drivers and platforms
    • Teensy 4: ISR-streamed FlexPWM RX + FlexIO TX ring (1000-LED loopback); fixed WS2812 loopback decode mismatches; ObjectFLED DMA buffer sized to the frame.
    • Platform-neutral early-boot watchdog loop guard (Teensy 4.x self-recovers before USB).
    • ESP32: compact RMT allocation records; PARLIO shares mutually exclusive waveform lookup storage; Wi-Fi/OTA linked only when a sketch uses fl::net.
    • AVR: Arduino Serial linked only when used; the power limiter drops 64-bit math; legacy white settings preserved during encoding.
  • Fixes
    • fl::aligned_alloc now honours the requested alignment on bare-metal targets (AVR/ESP8266/ARM).
    • ESP32 SPI bulk-transfer path builds again (stray exception specifier).
    • WASM: strips placed relative to shared screen bounds; screen maps with unset diameter render.
    • In-place upgrades over 3.10.5 link (tombstoned fl.system.sd+.cpp).
  • API and tooling
    • No-throw annotations enforced (FL_NO_EXCEPT) with an ESP release exception policy.
    • Non-release builds default to errors-only logging.
    • New lints: raw alignas banned in src/ (use fl/stl/align.h).
    • fbuild pinned to 2.5.39.
