PatternSpace 2.3 adds clearer output diagnostics, offline profile checks and new LUT analysis views. • Output Check reviews display and SDI configuration, profile and gamma-table observations, HDR headroom and a personal setup checklist. • Signal Details separates received values, app mapping and prepared/emitted SDI software frames. Refresh, copy and export observations without changing output; send individual range or code-step probes explicitly. Physical output accuracy still requires external capture. • ICC Profiles adds Verify: compare an offline ColorSync/Core Graphics conversion with a display profile’s matrix/TRC description and save JSON or CSV results. Identity comparisons are refused; Apple’s near-black inverse-slope cap is identified separately. This is a numerical check, not a display measurement. • A Calibration Workflow guide explains characterization, verification, activation and measurement through the same SDR Reference preset. • LUT Analysis adds Patterns: compare before/after calibration swatches and code values for grey ramps, primary/secondary ramps, gamut sweeps and ColorChecker 24 at the selected step or prepared export. • Export… now lives in the LUT Tools bottom bar (⌘E) and exports the whole chain from any selected step. It prepares the artifact when needed, shows status and avoids doubled file extensions. Esc closes the window. • New Settings controls let you turn off crash reports and anonymous performance measurements. Optional Share detailed diagnostics is off by default; it adds error messages, file/folder names, activity logs and a random installation identifier. Enabling it takes effect at next launch; disabling it takes effect immediately. • Previews and output continue while the Export Diagnostics save panel is open. • PatternSpace JSON SDK 1.1.0 adds capability-gated signal snapshots and guarded single-sample probes.

PatternSpace 2.2 adds detailed LUT analysis and more control over LUT chains, alongside clearer HDR setup and output diagnostics. • Explore every LUT step with Curves, RGB Slices and Points views, including code-value changes and channel balance. • Use the Filter node to smooth, sharpen or relax a correction, and choose common Full and Legal signal-range conversions in Adjust. • Classify LUTs for calibration use and review neutral-axis reversals, separability, crosstalk and grey-axis span. • Compare each step with the exact LUT export will write. • HDR guidance now points to the macOS High Dynamic Range setting when a display reports no EDR headroom. Peak White labels follow the active preset, and display diagnostics report the effective output path and values. • ICC Profiles adds a choice between parametric and sampled tone curves for gamma-based profiles. • Repair grey-axis reversals with the Fix node and optional 0–1 clamping. Review inverse coverage and round-trip reports before export; these are numerical diagnostics, not display measurements. • Blank and Resume the selected output, see who owns it, and choose an optional inactivity timer. The timer measures time without output commands, not meter completion. • DeckLink HDR: with Pro and the separate SDI add-on, compatible hardware offers 1080p/UHD PQ and HLG with static HDR metadata. Available modes depend on the device and single-link support. • Export preparation is automatic: select Export to prepare and verify the LUT or ICC artifact, then refresh it as settings change. Progress, Cancel and Retry keep you in control; preparation stays free. • A pinned Analysis widget gives live feedback. Overview arranges summary and diagnostic cards to fit the window; Curves, Slices and Points open in an Analysis window with its own step selection (⌥⌘A). • Source cards and a shared file picker simplify loading; replacement keeps the working LUT until the new file loads and validates. • Advanced invertibility analysis is requested from Overview with Pro. Sampled solver results remain free, and large analyses keep the app responsive. • Filter and copy Activity Log entries, or export session diagnostics for support. SDR library stimuli now follow the selected preset consistently. • Clearer Pro access and retryable purchase loading; CalMAN still requires its own UPGCI support. SDI keeps signal settings, supports lower frame rates reliably, and requires explicit recovery after an output timeout. • DeckLink configuration separates Video Mode, Signal and Container and adds mastering-display choices. UHD frames build faster, RGB sampling is confirmed as 4:4:4, and SDI signal settings remain independent of display presets. Superseded patch requests complete reliably. • Blank persists through sleep and wake; local takeover of a connected controller asks for confirmation. PatternSpace JSON adds output.blank, output.resume and output-owner status.

PatternSpace 2.1 makes LUT Tools faster, clearer and more dependable. • Faster exports: Cube and other text-based LUT formats export about 5× faster, and inverting large LUTs is much quicker. • Cancel Prepare at any time: a long Prepare now stops within a moment of pressing Cancel. • Clearer inversion results: Invert and Subtract list any samples they could not invert exactly, and inversion errors name the channel and the cause. • Safer ICC DeviceLink export: Export writes exactly the profile validated by Prepare. When calibration curves (VCGT) can't be included, Prepare explains why instead of silently leaving them out. • ICC Profiles: matrix profiles with sampled tone curves are no longer labelled as 3D-LUT profiles, and assignment verification now also checks the white point and calibration curves. • Clearer wording across LUT Tools, the purchase sheets and store messages; upgrade buttons show the live App Store price. • Fixed: Subtract with a 1D LUT failed to export with "Unsupported LUT structure".

PatternSpace 2.0 adds a dedicated SDI output path and LUT preparation tools for your Mac calibration workflow. • DeckLink SDI Output: a separate one-time purchase for SDR calibration patches through compatible Blackmagic Design DeckLink and UltraStudio hardware. Requires Desktop Video 16.4.x. Supported output is progressive 720p or 1080p, 10-bit YCbCr, Video (Legal) range, BT.709 and gamma 2.4. Available modes depend on the device; Library patterns, UHD and HDR are not supported over SDI in this release. • LUT Tools (Beta): build a chain from an identity transform or imported LUT; compose transforms, adjust ASC CDL and scaling, inspect neutral-axis curves, and prepare exports in supported formats. Preparation is free and export is included in Pro. • Supported LUT interchange includes Cube, selected 3DL dialects, a supported subset of CLF, and additional grading and broadcast formats. ARRI Look import has format-specific fidelity limits; see the LUT Tools guide. • Subtract and Invert use numerical inversion. Review their results: they cannot exactly recover information lost through clipping or non-invertible transforms. • Export LUT chains as RGB-to-RGB ICC DeviceLink profiles for compatible software. DeviceLink export is separate from the SDR display-profile workflow in ICC Profiles. DeckLink SDI Output and Pro are independent purchases. ColourSpace, CalMAN and PGenerator automation requires Pro in addition to the SDI add-on when using SDI output.

• ICC Profile Builder: Build SDR matrix/TRC ICC profiles from editable primaries and transfer functions; inspect a display or imported profile, then compare any profile with a design or output preset. • LUT Import: Imports 1D or separable 3D .cube calibration LUTs and uses only their per-channel curves in the SDR matrix/TRC/VCGT workflow—no display measurement or full 3D color transform. • Preview red, green, and blue transfer curves before exporting an ICC profile with a vcgt tag. • Live Apply: Apply curves to the selected display for the current session only; it is fully reversible. • Guided profile assignment exports the files, opens macOS Color Settings for selection, then reads back the active profile. It confirms profile state, not display accuracy; its record survives topology changes and reconnects. • Pro unlocks ICC export, Live Apply, and assignment of generated or calibrated profiles. Assigning an external .icc file remains free. • Metal rendering: The main Generator window now uses the full Metal output pipeline, including output presets, EDR-clamped Peak White, and live patterns.
