+## v0.10.0
+
+Ports and adapters refactor.
+
+- Extract shared manifest types into `internal/manifest/types` leaf package.
+- Extract SQLite adapter into `internal/manifest/sqlite`: Store, Adapter, LogWriter.
+- Extract JSONL adapter into `internal/manifest/jsonl`: Store, Adapter.
+- `modernc.org/sqlite` import isolated to `internal/manifest/sqlite/adapter.go`.
+- Registry pattern: `manifest.Default` provides adapter-backed `ParseFormat`/`Open`/`OpenLogWriter`.
+- Adapter-agnostic `ConvertManifest` in `types/` for JSONL↔SQLite conversion.
+- `MemoryAdapter` for in-memory manifest testing.
+- CLI uses `manifest.Default` registry directly; zero concrete adapter references.
+- SQLite `LogWriter` type assertion moved from central code into `SQLiteAdapter`.
+- `Manifest` interface now includes `Entries()`; `EntryReader` removed.
+- No behavior changes, no new features.
+- 100% statement coverage across all 6 packages.

-# v0.9.4
+# v0.10.0
 
-This release adds `doctor` diagnostics for Photos access and backups.
+Ports and adapters refactor. No user-visible changes.
 
 ## Highlights
 
-- Add `doctor` to check Photos access.
+- Extract manifest types, registry, and conversion logic into `internal/manifest/types`.
-- Add `doctor --out <dir>` to report backup directory, manifest entries, and failure count.
+- Extract SQLite adapter into `internal/manifest/sqlite` with its own store, adapter, and log writer.
-- Add `doctor --json` for scriptable diagnostics.
+- Extract JSONL adapter into `internal/manifest/jsonl` with its own store and adapter.
-- `doctor` is read-only and does not modify backup data.
+- Isolate `modernc.org/sqlite` import to the SQLite adapter package only.
+- Replace central `Open`/`ParseFormat`/`OpenLogWriter` with adapter-backed registry.
+- Adapter-agnostic manifest conversion via `ConvertManifest`.
+- SQLite log writer selection moved from central code into `SQLiteAdapter`.
+- CLI uses `manifest.Default` registry; no direct references to concrete JSONL or SQLite types.
+- `MemoryAdapter` available for in-memory manifest tests.
+- 100% statement coverage across all 6 packages.
+- No behavior changes.
 
 ## Assets
 
 - `photoscli`: Apple Silicon macOS binary (`darwin/arm64`).
-- `photoscli-0.9.4-macos-arm64.zip`: Apple Silicon binary plus README, USERGUIDE, and CHANGELOG.
+- `photoscli-0.10.0-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.
