All notable changes to this project will be documented in this file.

and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).



## [0.1.1] - 2026-04-08



### Fixed



- `Serializer.to_db/1` and `Serializer.from_db/4` now serialize/deserialize the `runtime_metadata` field from `Hephaestus.Core.Instance`, preventing data loss on persistence.



### Changed



- Bumped `hephaestus` dependency to `~> 0.1.4` (required for `runtime_metadata` support).



## [0.1.0] - 2026-04-07



### Added



- Ecto schema (`HephaestusEcto.Storage.WorkflowInstance`) for persisting workflow instances in a single `workflow_instances` table with JSONB `state` column and GIN indexing.

- `HephaestusEcto.Serializer` for converting between `Hephaestus.Instance` structs and database records.

- `HephaestusEcto.Storage` implementing the `Hephaestus.Storage` behaviour with full CRUD operations (`save/2`, `get/2`, `delete/2`, `list/1`).

- `HephaestusEcto.Migration` module for creating and dropping the `workflow_instances` table.

- `mix hephaestus_ecto.gen.migration` task for generating migration files into the host application.

- Concurrency test suite validating parallel writes and reads.

- Full `@moduledoc` and `@doc` documentation for all public modules and functions.

- README with setup, usage, and architecture overview.

- Hex package configuration with MIT license.
