Walkthrough

Adds a release changelog step; updates versioning and CHANGELOG. Introduces ESP32 IDFv4 envs, library upgrades, DMX options, and partition tweaks. Major refactors include bus management (vector-based, parallel I2S support), FX timing/memory, Segment API (setUp→setGeometry), primary color rename (col→colPri), config I/O changes, UI updates, remote handling deferral, and multiple stability fixes.

Cohort / File(s)	Summary
CI Release Workflow .github/workflows/release.yml	Adds changelog generation step and wires its output to draft release body.

Build Scripts pio-scripts/build_ui.py	Adds Node preflight, runs npm install then build with error handling.
PlatformIO Configs platformio.ini, platformio_override.sample.ini	Adds ESP32 IDF v4 envs (esp32dev_V4), upgrades libraries, switches AsyncTCP, adds DMX, stack size flags, partitions, AR sample envs and LED macro changes.
Usermods fixes usermods/BME280_v2/usermod_bme280.h, usermods/audioreactive/audio_reactive.h, usermods/usermod_rotary_brightness_color/usermod_rotary_brightness_color.h, usermods/usermod_v2_rotary_encoder_ui_ALT/usermod_v2_rotary_encoder_ui_ALT.h, usermods/rgb-rotary-encoder/readme.md	BME280 temp unit init; audioreactive peak timing via frame time; use colPri instead of col in rotary modules; update ESP Rotary lib version in docs.
FX Engine Updates wled00/FX.h, wled00/FX.cpp, wled00/FX_fcn.cpp	Introduces MIN_FRAME_DELAY; Segment API changes (setGeometry, setName, differs const); per-LED buffers and signed loops; timing/show logic refactor; fade/out rewrite; updates Percent mode data string.
Bus Subsystem Refactor wled00/bus_manager.h, wled00/bus_manager.cpp, wled00/bus_wrapper.h, wled00/const.h	Switch to std::vector busses, const-correct APIs, unsigned indices, memUsage helpers, parallel I2S handling per ESP32 variant, new limits/macros for ESP32 families.
Config and Core Flow wled00/cfg.cpp, wled00/wled.h, wled00/wled.cpp, wled00/fcn_declare.h	deserializeConfigFromFS now returns bool; introduce useParallelI2S flag (ESP32*); globals: col→colPri, notify defaults tweaked; busConfigs becomes std::vector; add JSON helpers; WiZ data handler and deferred remote entry.
Networking/Remote wled00/udp.cpp, wled00/remote.cpp, wled00/network.cpp	setUp→setGeometry in UDP; ESPNOW receive renamed to handleWiZdata and deferred processing via handleRemote(); add default WiFi event debug log.
JSON/Presets/Util wled00/json.cpp, wled00/presets.cpp, wled00/util.cpp	Segment JSON uses setGeometry with 2D flags; safer apply with suspend/wait; ESP32x wait during presets; extend getVal parsing for random/inc forms.
Pins/Buttons/Hue/MQTT/XML wled00/pin_manager.cpp, wled00/button.cpp, wled00/hue.cpp, wled00/mqtt.cpp, wled00/xml.cpp	ESP32-variant pin checks; use colPri for color ops in buttons/hue/MQTT/XML; add fillWLEDVersion; expose parallel output in LEDs settings XML.
LED State Handling wled00/led.cpp, wled00/set.cpp	Migrate primary color to colPri across state/NL/Alexa; trigger on final brightness; set PR (parallel I2S) from settings; move to vector-based busConfigs construction.
Web UI (JS/HTML) wled00/data/common.js, wled00/data/index.htm, wled00/data/index.js, wled00/data/settings_leds.htm, wled00/data/settings_sec.htm, wled00/data/update.htm	Pointer events for tooltips; add id to “Add palette” buttons; dynamic palette UI; color-slot handling refactor; new hardware-aware LED settings with parallel I2S option and FPS warnings; show installed version labels.
