What's new

Repeatable LUT delivery

• Save and reopen sessions: Keep embedded sources, nested operations, and LUT/ICC export settings together in a .pslutchain file. Saving and opening sessions are free.
• One Outputs list: The top of the Export inspector lists everything that will be written. Add Output adds more LUT formats and grid sizes, Add ICC Profile adds one ICC DeviceLink, and with several outputs the export button becomes Export All…, with file-name templates, overwrite confirmation, cancellation, and per-output results and quality warnings.
• PDF delivery reports: Turn on Include report to record the source, chain, chain-to-export difference, export verification, warnings, grey-axis curves, and an optional reference-LUT comparison with each export.
• Clearer settings: General, Purchases, and Privacy now have separate tabs; choose System, Light, or Dark appearance for PatternSpace’s windows. Purchases shows Pro and DeckLink SDI Output with Restore Purchases. Blank after inactivity is now in Settings › General › Output.
• Desktop Video 16.x: DeckLink SDI Output accepts Blackmagic Desktop Video 16.4 or any later 16.x release, so a Mac updated to 16.5 no longer reports the runtime as unavailable.
• More responsive output: The output window and preview redraw only when their visible content or settings change, JSON display lists read each display profile once per request, and opening the output window no longer hangs on a cold shader cache.

Output confidence

• Output Check: Review display/SDI configuration, profile and gamma-table observations, HDR headroom, and your brightness/reference-mode assumptions.
• Signal Details: Compare received source values, app mapping, and prepared/emitted SDI software frames. Physical cable values remain unknown without external capture.
• Explicit diagnostic probes: Choose one range-boundary or code-step sample and send it deliberately. Opening, refreshing, copying, or exporting observations does not send a patch.
• ICC Verify: Compare an offline ColorSync/Core Graphics conversion with a profile’s matrix/TRC description and export JSON/CSV results. Identity comparisons are refused; Apple’s near-black inverse-slope cap is explained separately. This is a numeric check, not a display measurement.
• Calibration Workflow guide: Follow characterization, verification, activation and measurement through the same SDR Reference preset.
• LUT Patterns: Compare before/after calibration patches and code values at a selected step or prepared export: grey ramps, primary/secondary ramps, gamut sweeps and ColorChecker 24.
• Simpler LUT export: Export… in the bottom bar (⌘E) exports the whole chain from any selected step and prepares it if needed. Status is visible; doubled file extensions are fixed and Esc closes the window.
• Reporting controls: New Settings let you turn off crash reports, release-health sessions and anonymous performance measurements. Optional detailed diagnostics is off by default and adds error messages, file/folder names, activity logs and a random installation identifier. Enabling details takes effect next launch; disabling takes effect immediately.
• Uninterrupted previews: Previews and output continue while the Export Diagnostics save panel is open.
• SDK 1.1.0: Capability-gated read-only snapshots and guarded probes. Legacy advertised bit depth describes the source/container contract, not a measured HDMI link.

• Detailed LUT analysis — Explore every step with Curves, RGB Slices and Points views. Review channel balance, code-value changes, reversals, separability and crosstalk, and compare the chain with the exact LUT export will write. Read the LUT Tools guide.
• Automatic export preparation — Select Export to prepare and verify the LUT or ICC artifact automatically. Chain and settings changes refresh the result, with progress, Cancel and Retry. Preparation remains free.
• A clearer LUT workbench — Pinned Analysis gives live feedback above the settings. Overview arranges summary and diagnostic cards to fit the window; the Analysis window has its own step selection and opens with ⌥⌘A. Source cards and a shared file picker keep the working LUT until a replacement loads and validates.
• Filter and signal-range controls — Smooth, sharpen or relax a correction with the new Filter step. Adjust also includes presets for common Full and Legal signal-range conversions.
• LUT Fix and inverse reports — Repair grey-axis reversals with optional 0–1 clamping. Request advanced invertibility analysis from Overview with Pro to review inverse coverage, fold evidence and round trips; sampled solver results remain free, and large analyses keep the app responsive. These reports describe numerical behavior before encoding, not measured display accuracy or guaranteed invertibility.
• Blank, Resume and output ownership — Blank the selected display or SDI output without ending the session, then restore the retained output. Blanking persists through sleep and wake; local takeover asks for confirmation while a controller is active. See who controls the output and choose an optional inactivity timer; elapsed time does not establish that a meter has finished.
• Capability-gated DeckLink HDR — With Pro and the separate SDI add-on, compatible hardware offers 1080p/UHD PQ and HLG with static HDR metadata and mastering-display choices. Configuration separates Video Mode, Signal and Container. Available modes depend on the device and single-link support.
• ICC tone-curve choice — Choose parametric or sampled tone curves for gamma-based ICC profiles.

• DeckLink SDI Output — A separate one-time purchase for solid and window calibration patches through supported Blackmagic hardware. Production output supports progressive 720p/1080p SDR, 10-bit YCbCr, Video (Legal) range, BT.709, and gamma 2.4. Requires Desktop Video 16.4.x. ColourSpace, CalMAN, and PGenerator automation also require Pro. Read the SDI setup guide.
• LUT Tools (Beta) — Build a chain from an imported LUT or identity transform. Compose branches, apply ASC CDL and scaling adjustments, inspect the result, and prepare a converted export. Subtract and Invert use numerical inversion with limits where source data is clipped or non-invertible. Preparation is free; writing files requires Pro. Explore the LUT workflow.
• LUT interchange and export checks — Supported Cube, 3DL, CLF, and other LUT formats include format-specific checks and conversion notices. ARRI Look import has documented fidelity limits. Prepared LUT exports are re-read for comparison; these checks do not certify a display's measured accuracy.
• ICC DeviceLink export — Export a baked 33³ RGB-to-RGB chain for software that supports this ICC DeviceLink type. The separate ICC Profiles window retains the SDR display-profile and per-channel VCGT workflows. A DeviceLink is not a system display profile.

• ICC Profile Builder — Build a matrix/TRC ICC profile from editable primaries and an SDR transfer function (sRGB, γ2.2, γ2.4, BT.1886, Linear), with a live CIE-xy gamut plot, white-point CCT, and gamut coverage. Inspect the active display profile or any .icc/.icm file, and compare any profile against a build spec or output preset. Building and inspecting are free; exporting a .icc requires PatternSpace Pro.
• Calibrate from a LUT (VCGT) — Import a .cube calibration LUT and export it as an ICC profile with a VCGT tag, or apply the calibration's gamma curves live to the selected display — session-volatile, verified by reading the ramp back, and auto-reverted on the next launch. Exporting and live apply require Pro.
• Guided profile assignment & restore — Assign a generated or calibrated profile as the display's system profile through a guided handoff, confirmed by reading the active profile back. Assignments are keyed to the physical display and survive reconnecting monitors, with a guided restore to the previous profile.
• Metal/EDR in-window preview — The Generator preview now renders active patches and built-in patterns through the same Metal pipeline as the fullscreen patch window — including output presets, EDR-clamped Peak White, and measurement range.
• Platform-aware help — Help articles now show macOS-specific guidance and screenshots, with the ICC Profile Builder guide delivered as a macOS-only article.
• App Store–promoted Pro — PatternSpace Pro is now eligible for promotion directly on its App Store product page.

• Free SDR output tier — Device Native, Display SDR, and the full set of 14 SDR Reference presets (sRGB, Adobe RGB, P3, BT.709/BT.1886, BT.2020, DCI, and more), with Full and Legal measurement range — no purchase required.
• PatternSpace Remote evaluation — The first-party WebSocket/JSON protocol is now free to try: pair a client and render up to 25 patches per session. Pro removes the limit.
• Advanced HDR output — HDR PQ (untone-mapped), system-tone-mapped HDR (P3-D65 and BT.2020 ST 2084), Display HDR, and Linear HDR presets, with Peak White and EDR controls plus live EDR headroom diagnostics. (Pro)
• Preset Diagnostics Inspector — Gamut, transfer function, encoding, EDR headroom, estimated peak luminance, and the active display profile at a glance.
• Per-display Peak White — Each display keeps its own Peak White value with display-aware clamping, plus a display details popover with profile and EDR information.

• Mac App Store release — PatternSpace launches on the Mac App Store as a free download with a one-time PatternSpace Pro in-app purchase.
• PatternSpace Remote protocol — A first-party WebSocket/JSON-RPC remote-control protocol with 4-digit pairing codes, pattern listing, patch display control, device snapshots, and event publishing — with an open SDK on GitHub.
• PatternSpace Pro — StoreKit-based one-time purchase with restore, refund handling, and Family Sharing support.
• Built-in help system — Searchable help topics covering every protocol and workflow, localized in English, German, Spanish, French, and Italian.
• Connection UI redesign — A shared connection shell with per-protocol setup guides for PatternSpace Remote, ColourSpace, CalMAN, and PGenerator, plus a reachable-address picker.

• Library Cleanup — Removed custom and parametric placeholder cells from the pattern library to focus on predefined, high-quality reference patterns.
• Search Capability — Initial implementation of cross-category pattern search (infrastructure and UI).

• Logarithmic Checkerboard — New rendering logic for precise logarithmic grid spacing across 13 levels.
• Check Composite Pattern — Combined diagnostic pattern with real-time labeling support.
• ColorChecker SG — Implementation of the 140-patch Semi-Gloss reference target.
• Resolution Wedge & Star — Advanced diagnostic patterns for sharpness and aliasing evaluation.
• Geometry & Clipping References — New test patterns for aspect ratio and signal range verification.
• Shader Comparison Report — Automated validation system comparing Metal shader output against reference PNG assets using PSNR metrics.
• Double-tap Gesture — New interaction to quickly toggle the patch window on touch-enabled or trackpad devices.
• Mobile-responsive Website — Initial launch of the PatternSpace website with responsive navigation and documentation.

• Calibration pattern category — Metal-shader-rendered calibration patterns with asset-backed previews: Brightness, Contrast, Clipping Range, Contrast Ratio, Contrast Min/Max, Sharpness, Gray Balance, Bars and Black, FALD Stress, Color Ramps (1–3), ColorChecker Classic, and ColorChecker SG.
• PGenerator protocol support — Full emulation of the PGenerator network protocol, including multi-command bootstrap, pattern catalog listing, system status, configuration commands, and multi-bit depth rectangle support.
• ColourSpace auto-discovery — Automatic network discovery with sender IP validation and connection lifecycle management.
• CalMAN protocol support — Connect via CalMAN's Unified Pattern Generator Control Interface (UPGCI) with full geometry and color mapping.
• Pattern library — Comprehensive GPU-rendered local pattern library across six categories:
