 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project follows semantic versioning.
 
+## [0.6.0] - 2026-06-17
+
+### Added
+- Preset ID constants for three Linear HDR presets: `extLinearSRGBHDR`, `linearHDRP3D65`, `linearHDRBT2020`
+- `OutputColorPresetFamily.linearHDR` convenience constant for clients reading Linear HDR preset metadata
+
+### Changed
+- `PatternSpaceProtocolMetadata.sdkVersion` is now `0.6.0`; PatternSpace JSON protocol remains `1.2`
+- Protocol documentation and README examples now describe Linear HDR presets and Peak White gating semantics
+

 ### Output Color Preset Catalog
 
-Output presets replace the old closed color-management mode API. The SDK defines convenience constants for known preset IDs, but IDs and metadata vocabularies are open strings. Adding a host preset should not require an SDK update. SDK `0.5.1` includes convenience constants for the Phase 3 SDR reference vocabulary, including P3-D65 gamma 2.2/2.4/2.6 and the open-string `proPhotoROMM` transfer/input encoding token.
+Output presets replace the old closed color-management mode API. The SDK defines convenience constants for known preset IDs, but IDs and metadata vocabularies are open strings. Adding a host preset should not require an SDK update. SDK `0.6.0` includes convenience constants for SDR Reference, HDR PQ, and Linear HDR presets, including `extLinearSRGBHDR`, `linearHDRP3D65`, and `linearHDRBT2020`.
+
+Remote patches follow the active preset's input encoding exactly: SDR Reference decodes the configured transfer function, HDR PQ decodes normalized PQ signals, Linear HDR treats values as linear light, and Device Native passes values through raw. Built-in PatternSpace Library patterns are generated internally in linear light. They use the active preset's output color space when applicable, and Linear HDR presets apply Peak White. HDR PQ presets do not make Library patterns PQ-encoded; use HDR PQ when an external measurement workflow sends PQ patch values.
 
 `catalogRevision` is an opaque cache token sourced from the host catalog. It is identical across `display.listOutputColorPresets` and `display.getOutputColorPreset` while the catalog is unchanged, and it changes whenever the preset set, summary metadata, or full config for any preset changes. Clients may cache full configs by `(presetId, catalogRevision)`.
