 This changelog is maintained from git history plus the published Gitea release series. Future releases should update this file and publish matching release notes on the release page.
 
+## v0.8.6
+
+XMP keyword and rating controls release.
+
+- Add `--xmp-keywords album-path|album|none` for generated sidecars.
+- Add `--xmp-rating favorite|none` for generated sidecars.
+- Keep existing keyword/rating behavior as defaults with `album-path` and `favorite`.
+
+## v0.8.5
+
+XMP privacy controls release.
+
+- Add `--xmp-privacy keep|strip-location|strip-address` for generated sidecars.
+- Keep existing XMP location/address behavior as the default with `keep`.
+- Allow GPS coordinates to be kept while reverse-geocoded address fields are omitted with `strip-address`.
+- Allow both GPS coordinates and address fields to be omitted with `strip-location`.
+
+## v0.8.4
+
+Strict XMP sidecar verification release.
+
+- Add `verify --sidecar --strict` to require photoscli XMP schema metadata, sidecar generator metadata, and matching exported filename metadata.
+- Keep existing `verify --sidecar` behavior unchanged for backup-wide existence, readability, and asset-ID checks.
+
+## v0.8.3
+
+XMP sidecar inspection release.
+
+- Add `sidecar inspect <file.xmp>` to print key photoscli metadata from generated XMP sidecars.
+- Add `sidecar inspect <file.xmp> --json` for scriptable inspection output.
+
+## v0.8.2
+
+Metadata-only XMP refresh release.
+
+- Add `--metadata-only` for manifest-based XMP sidecar generation without re-exporting media files.
+- Support metadata-only refresh for both `export` and `backup-all` when used with `--sidecar xmp`.
+- Require a manifest for metadata-only mode so existing media paths are resolved safely.
+- Keep media files untouched while overwriting/regenerating generated XMP sidecars.
+- Support `--reverse-geocode` during metadata-only sidecar refresh.
+
 ## v0.8.1
 
 XMP standards and sidecar verification release.

 Sidecars also include richer public PhotoKit metadata where available: modification date, duration, hidden state, adjustment state, media subtypes, source type, playback style, burst data, GPS coordinates, adjustment info, structured asset resources, standard XMP dates, EXIF GPS coordinates, favorite rating, and album/folder keywords. Add `--reverse-geocode` to include cached address fields from Apple MapKit for assets with GPS coordinates. Reverse geocoding requires macOS 26 or newer; on older macOS versions the export continues and XMP still includes GPS coordinates.
 
+Control XMP location metadata with `--xmp-privacy keep|strip-location|strip-address`. The default is `keep`. Use `strip-address` to omit reverse-geocoded address fields while keeping GPS coordinates, or `strip-location` to omit both GPS and address fields.

+Control generated XMP keywords and ratings with `--xmp-keywords album-path|album|none` and `--xmp-rating favorite|none`. Defaults preserve existing behavior: album/folder keywords and favorite assets mapped to `xmp:Rating="5"`.

 ```bash
 photoscli verify --out ./backup --sidecar

-# v0.8.1
+# v0.8.6
 
-This release improves XMP sidecar standards compatibility and adds sidecar verification.
+This release adds keyword and rating controls for generated XMP sidecars.
 
 ## Highlights
 
-- Add `photoscli:xmpSchemaVersion="2"` to generated XMP sidecars.
-- Add standard XMP mappings for favorite rating, metadata date, Photoshop date created, and EXIF GPS coordinates.
-- Add `dc:subject` keywords from album/folder context.
-- Add sidecar generator and generated timestamp metadata.
-- Add `verify --sidecar` for missing, zero-byte, unreadable, and asset-ID mismatched XMP sidecars.
-- Keep Vision/Core ML people, animal, object, and scene analysis out of this release.
+- Add `--xmp-keywords album-path|album|none`.
+- Add `--xmp-rating favorite|none`.
+- Keep existing behavior by default with album-path keywords and favorite-to-rating mapping.
+- Use these flags when another DAM or metadata tool should own keywords or ratings.
 
 ## Assets
 
 - `photoscli`: Apple Silicon macOS binary (`darwin/arm64`).
-- `photoscli-0.8.1-macos-arm64.zip`: Apple Silicon binary plus README, USERGUIDE, and CHANGELOG.
+- `photoscli-0.8.6-macos-arm64.zip`: Apple Silicon binary plus README, USERGUIDE, and CHANGELOG.
 - `USERGUIDE.md`: standalone user guide.
 
 Intel Macs are not currently a supported release target.

+Use strict verification for sidecars generated by recent photoscli versions:
+
+```bash
+./bin/photoscli verify --out ./PhotosBackup --sidecar --strict
+```
+
+Strict mode also checks photoscli schema metadata, generator metadata, and the exported filename recorded inside the sidecar.

+Inspect one generated sidecar when troubleshooting or scripting:
+
+```bash
+./bin/photoscli sidecar inspect ./PhotosBackup/IMG_0001.xmp

+
+Refresh metadata only for an existing manifest-backed backup:
+
+```bash
+./bin/photoscli backup-all --out ./PhotosBackup --sidecar xmp --metadata-only
+```
+
+Metadata-only mode does not re-export media files. It uses manifest paths to find existing files and rewrites generated `.xmp` sidecars next to them. It requires `--sidecar xmp` and an enabled manifest.
+
 If you explicitly request `--sidecar xmp` and the XMP file cannot be written, the asset is counted as failed.
