2026.11 Released

2026.11 June 14, 2026

NOTE: Support for macOS versions 10.15 and 11 will likely be dropped fairly soon as the tools we use to build xLights are dropping support.

-enh (charlie) Command palette (Ctrl/Cmd+Shift+K): a searchable launcher for any menu command or effect with fuzzy match, keyboard nav,

and SF Symbol icons on macOS (#6258).

(copy/fill/apply-palette, create from timing marks) and export region(s) as new

sequences (#6268).

-enh (cybercop23) Radial effect wheel popup on empty sequencer-grid double-click for quick keybinding/effect access (ignored on timing

tracks) (#6486).

-enh (cybercop23) Shift-drag effect edges in the sequencer grid to adjust fade-in/fade-out times (#6492).

-enh (agfazio) Drag/drop effects in the sequencer, including ghost drag-to-move (#6478).

-enh (cybercop23) Add a Cycles parameter (1-10) to Custom value curves to allow replication (#6488).

-enh (cybercop23) Add the ability to move the background image in Model Data (#5506).

-enh (cybercop23) Closing the Faces or States editor now prompts for confirmation before discarding (#6470).

-enh (scott) SubModels Symmetrize: choose Degree of Symmetry, rotation direction, and build order, all remembered between openings.

-enh (scott) Alternate-audio selection in Sequence Settings now supports multi-select.

-enh (scott) AI Services: ChatGPT, the Generic OpenAI client, and Ollama now fetch the model list from the server and present it as a

dropdown, including a model picker in the AI image generation dialog.

-enh (scott) Auto-discover WLED controllers via mDNS (_wled._tcp); discovered devices are added as DDP with auto-size/auto-layout.

-enh (derwin12) Add an HD upscale option for model export (#4228).

-enh (derwin12) Add a “Swap Start/End” right-click option to Single Line and Poly Line models (#5450).

-enh (dkulp) macOS: Export House Preview Video now uses AVFoundation (AVAssetWriter).

-enh (dkulp) Model video export and media transcoding now share a VideoWriter abstraction: AVFoundation on macOS (incl.

alpha-preserving, bit-exact uncompressed .mov at any size) and FFmpeg for AVI/MPEG-4.

-enh (dkulp) Add a “ProRes 4444 Video, *.mov” model export option: 4:4:4 near-lossless, much smaller than uncompressed RGB, and

decodes on all platforms.

-bug (dkulp) macOS: Model export failed when a filename was typed instead of chosen via the file dialog. The Export Sequence

dialog is now a format list + Next that always opens a Save As panel so the sandbox grants write access.

-change (dkulp) Model GIF export now uses a wx-free encoder (gif-h) shared with the iPad app, replacing the wxWidgets GIF writer.

channel numbers beyond the hardware maximum (#5584).

-bug (derwin12) Keep custom models centered in their bounding box after editing (#6452).

-bug (derwin12) Fix Moving Head color wheel showing wrong color choices when switching, and reset values when existing ones aren’t found

-bug (dkulp) Maybe fix crash closing a sequence/show folder before the sequencer tab fully exists (null EffectsPanel1 in

ResetAllPanelDefaultSettings).

-bug (dkulp) Harden the property-grid combo popup teardown against re-entrancy so hiding a deleting combo can’t repaint with a stale

property (top macOS crash).

-bug (dkulp) Fix crash undoing a model property change (null property-grid adapter when DoUndo re-selects the model before the

deferred grid rebuild).

-bug (dkulp) Fix PolyLine model crash when deleting a handle during placement (stale per-segment sizes ran the light distribution

past the point array).

-bug (dkulp) Fix Windows crash drawing color-vertex primitives when the accumulator type doesn’t match (null-check the dynamic_cast).
