# Changelog
## 1.1.0.0 — 2026-07-13
Major release: this set adds constructors to the public `ManifestError` and
`AuthoringError` sums.
### Breaking changes
- Added `ManifestByteOrderMark` so a leading UTF-8 BOM has a dedicated diagnostic.
- Added `AuthoringConcurrentModification` so a detected post-rename manifest clobber does
not silently report successful authoring.
### Fixes and behavior changes
- Stop automatic numbering before a successor would lose the sequence's leading zero and
become unreadable by the next authoring operation.
- Emit embedded SQL as one static primitive byte literal instead of one Template Haskell
expression per byte, making multi-megabyte payloads practical while preserving exact
bytes.
- Add `Database.PostgreSQL.Migrate.Embed.RecompilePlugin` for GHC 9.12. A module-local
`OPTIONS_GHC -fplugin=...` pragma makes the embedding module recompile on every build so
newly added or removed sibling SQL files rerun strict manifest membership validation.
- Document that migration authoring requires POSIX while manifest validation and embedding
remain portable, and describe the authoring helper's actual concurrency guarantees.
## 1.0.0.0 — 2026-07-10
- Initial stable release of manifest format v1, exact-byte Template Haskell embedding,
validation, and crash-conservative migration authoring.
