## [Unreleased]

---

## [0.11.2] - 2026-03-05

### Fixed

- Reverted the `from_avro_map/1` changes introduced in 0.11.0. The previous implementation incorrectly decoded union fields when all union member types had only nullable fields, always selecting the first type.

---

## [0.11.1] - 2026-02-18

---

## [0.11.0] - 2026-02-02

### Changed

- Enhanced `from_avro_map/1` to support backwards compatibility when schemas evolve. Nullable fields are no longer matched in the function signature, allowing newer versions of modules to successfully decode payloads encoded with older schema versions that don't include newly added nullable fields.

---

## [0.10.0] - 2025-11-07

### Fixed

- Fix issue where `Avrogen.Schema.external_dependencies` was wrongly identifying references to previously defined types as external dependencies.

---

## [0.9.0] - 2025-10-22

### Added

- Support for the `bytes`-backed `big-decimal` scalable precision decimal type added in v1.12.0. The non-standard, `string`-backed [`big_decimal`](lib/avrogen/avro/types/logical/decimal_string.ex) is still supported and now also accepts `big-decimal` as the logical type name.

---

## [0.8.6] - 2025-08-25

### Fixed

- Fix dialyzer issue for enum default values.

---

## [0.8.5] - 2025-07-18

### Changed

- Enhanced enum decoding to handle schema evolution gracefully. When `from_avro_map/1` encounters an unknown enum symbol and the enum defines a default value, it now uses the default instead of returning an error. This enables forward compatibility when new enum symbols are added in newer schema versions.

---

## [0.8.4] - 2025-05-06

### Fixed

- In-line the old version of `String.jaro_distance/2`, since the one introduced in Elixir 1.17.1 changes the behaviour

---

## [0.8.3] - 2025-04-11

### Fixed

- Using `Date.utc_today` instead of `Date.utc_now` which doesn't exist

---

## [0.8.2] - 2025-03-27

### Fixed

- Removed Noether dependency to avoid conflicts.

---

## [0.8.1] - 2025-02-25

### Fixed

- New `time/0` function as part of the `Random` module which was previously
  undefined after codegen

---

## [0.8.0] - 2025-01-22

### Changed

- Replaced `elixir_uuid` with `uniq`

---

## [0.7.0] - 2024-09-18

### Changed

- **Breaking change**: encoder will fail with a match error if the input is not
  serializable in Avro format.

---

## [0.6.6] - 2024-08-11

### Added

- `find_avsc_files!` function to find all `.avsc` files in a directory.
- `combined_schema` function to return a list of schemas sorted in topological
  order.

### Fixed

- Reintroduced guard in uuid logical type.

---

## [0.6.5] - 2024-07-05

### Added

- Support for additional logical types:
  - `Date` (`int`).
  - `TimeMillis` (`int`).
  - `TimeMicros` (`long`).
  - `TimestampMicros` (`long`).
  - `LocalTimestampMillis` (`long`).
  - `LocalTimestampMicros` (`long`).
