@hackage/pg-migrate-embed

Major release: this set adds constructors to the public ManifestError and AuthoringError sums.

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.

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.

Initial stable release of manifest format v1, exact-byte Template Haskell embedding, validation, and crash-conservative migration authoring.
