## Rationale The ALP (Adaptive Lossless floating-Point) encoding specification was recently merged into parquet-format via [apache/parquet-format#557](https://github.com/apache/parquet-format/pull/557) (vote: [[RESULT][VOTE] Add ALP encoding to the Parquet format](https://lists.apache.org/thread/ld025dzycrhm6dgh8p6157to7d9x8pon)), but it is not listed on the [Features and Versions](https://parquet.apache.org/docs/file-format/versions/) page. ## Changes - Add `encoding-alp` to `data/implementations/features/encodings.yaml`, which adds ALP to: - the *Forward incompatible features by version* table on the versions page - the implementation status matrix (all implementations show "unknown" until their support entries are updated) - ALP was merged after the parquet-format 2.13.0 release, so there is no release to point at yet. This PR adds a special `unreleased` entry to `parquet-format-releases.yaml` (source link: `2.13.0..master` compare) and teaches the `format-versions` shortcode to render features whose release has no tag. When 2.14.0 ships, the entry can be switched to the real version. ## Rendered | Feature | Release | Source | PRs | Approved | |---|---|---|---|---| | [ALP](https://github.com/apache/parquet-format/blob/master/Encodings.md#adaptive-lossless-floating-point-alp--10) | unreleased | [2.13.0..master](https://github.com/apache/parquet-format/compare/apache-parquet-format-2.13.0...master) | [#557](https://github.com/apache/parquet-format/pull/557) | [2026-07-23](https://lists.apache.org/thread/ld025dzycrhm6dgh8p6157to7d9x8pon) | 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
