Happy New Year! 🥂

I hope you had a great holiday, spending time with your loved ones. We're starting into 2026 with a bunch of bug fixes and improvements for WLED-MM that we've been working on over the last year. As always, our goal is to deliver the best experience on exciting hardware, especially HUB75 and large audioreactive LED installations. The HUB75 rig I'm using at the moment is a 192x64 matrix (3 chained 64x64 modules), powered by an ESP32-S3 with PSRAM and 16MB flash memory (MoonHub adapter by @lost-hope). In most effects, WLED-MM is able to deliver solid 25-45fps on this setup, even when receiving a real-time DDP stream.

We've made network protocols like DDP and Art-Net more stable and perform better. And Audioreactive has become better again. Scrolling text made the first baby steps towards supporting multi-language and unicode letters in PR #282. Many WS2812b LEDs are now working flicker-free thanks to a new RMT driver by @willmmiles in PR #308. Particle-FX from upstream are integrated into WLED-MM now (thanks @DedeHai).

Finally, we're saying goodbye to 8266 with this release. The code still compiles for 8266, but there was hardly any testing on 8266 boards.

Our firmware builds now default to the newer "V4" Espressif framework. We suggest using "V4" builds on classic esp32; esp32-S3/-S2/-C3 were always using "V4" so all our builds are now based in the same framework. If you're having problems updating your esp32 from upstream WLED 0.15, try the "ESP32_compat" build. It has fewer features and lower performance, but it's meant to be OTA compatible with upstream 0.15.x.

Highlights

• Realtime Mode (DDP, Art-Net, etc) stability and performance improvements
• New Particle-FX (upstream backport)
• GIF Player image effect and PixelForge tool (upstream 0.16 backport)
• flicker-free LEDs driver for esp32 and esp32-S3 (upstream 0.15.4 backport, "V4" builds only)
• No more corrupted presets!
• effect improvements and speedups for large fixtures
• Audioreactive sound sync: reduced latency, better handling of datastream
• Moved to newer "V4" framework for improved stability and better performance

what's the difference to Aircoookie/WLED ?

WLED-MM is a fork that concentrates on supporting large installs and advanced audio analysis. We also use our fork for trying new ideas, that may later become part of WLED upstream. Due to chip capabilities, we mainly use "classic" esp32 and ESP32-S3 with PSRAM, or esp32-s2 for smaller setups. Esp32-C3 is supported however usually we don't spend time optimizing for it.

If you have an esp32-P4 board, you might want to try the high-performance ESP32-P4 fork by @troyhacks.

We work closely with upstream WLED developers, and our ultimate goal is for all WLED-MM improvements to be included in future releases of WLED.

Firmware binaries:

firmware images for common boards are included in the "Assets" section - click on "show all assets" to see them all (~31 files). Please be aware that boards with 4MB flash will have some features disabled due to flash size limits. A detailed list of "what's included in each build" is in work 😅, and will be added here once it's done.

Full Changelog: v14.5.0-beta...v14.7.1

We're thrilled to bring you a new release of our latest MoonModules WLED, perfect for your holiday projects!

Apart from technical changes:

• We changed our versioning scheme - you will notice that this release is not 0.14.4-b34 but 14.5.0-beta (we basically skipped the leading 0.)
• Licensing changed from GPLv3 to EUPL-1.2 (to align with upstream WLED licensing)
• Just a heads-up: ESP8266 support is being phased out with this release, and it might be removed in the next release.

A few new features didn't make it in time and will be added soon with a new release - see "Known Limitations and upcoming enhancements" 😃.

Firmware binaries:

firmware images for common boards are included in the "Assets" section.

Known Limitations and upcoming enhancements

The following features and bugfixes are still pending:

• currently you can't use "custom bus start indices" (LED settings) to mirror outputs. A fix is in work.
• HUB75 setup: currently all your HUB75 panels are put into one horizontal row (i.e. a chain of 4 panels 32x32 => 128x32)
• HUB75 settings need more panel driver options (chipset, panel layout).

WLED-MM will continue to follow WLED upstream ("AC WLED") where we focus on cherry-picking the best and stable features.
Current status is:

• Bugfixes: close to AC 0.15.0 (including UI stability improvements)
• Features: slightly behind 0.14.4 (missing: latest LED drivers, improved effect crossfading, simple UI, reverse proxy support)
• Audio: many unique enhancements -> 2 years ahead of AC WLED.
• Many effects can run much faster, compared to standard AC WLED.
• Improved stability with large fixtures
• You can use very large LED maps without running into low memory problems
• Some unique features - like HUB75 support, DMX input, MM specific usermods, better LEDs preview, better support for advanced audio and lighting equipment.

• Read What binary should I use?

This is a maintenance release for -b29, including relevant bugfixes from upstream up to 0.14.1.

News (MM specific)

• palettes preview with gamma corrections. Palettes on screen are now much closer to how it looks on your LEDs: example
• bugfix: "segment off" button is finally(!) working (#90)
• Bugfix for sound sync "Receive or Local" mode - avoid that local samples sneak in between network sound packets
• some speed optimizations

Other important bugfixes

• Fix for UI crashes with many segments or frequent JSON requests (wled#3648)
• Fixing a crash when Streaming LEDs over UDP (wled#3672)

Full Changelog: v0.14.0-beta.29...v0.14.1-beta.30

What binary should I use?

This release provides a critical bugfix (#104 random crashes when "use global LED buffer" is enabled). In addition, several bugfixes from upstream and a few MM specific enhancements are included in this version.

New MM features

• UDP sound sync - sequence checking can be disabled in settings (useful if several units send sound)
• Audio Reactive effects: enhanced versions of "Fireworks", "Fireworks Starburst", "Popcorn" (#103) - back-ported from WLED-SR. These "audio enhanced" effects are triggered by sound. Like clapping of hands, music starts, beats, fireworks explosions.
• MM build environment for ESP32-C3 Mini/Zero/SuperMini (#101, #102)

What else?

Our 4MB "XL" build has (again) hit the flash size limit, so we had to remove two usermods (buzzer, sn_photoresistor). If you want to run "XL" builds, our suggestion is to use a board with 16MB flash, like this ESP32 WROOM32E 16MB.
