# Versions and changelog

Last updated 10 September 2026
Source: https://plas.redia.dk/en/changelog/

What is running now, and what changed along the way. The versions are read from PLAS Status, the only version authority; the changes are the source's own words alongside the measured difference between the specifications.

## Versions

| API | Role | In production | In specification | Reference |
| --- | --- | --- | --- | --- |
| Provider API | Entry point | v0.6.5 | v0.6.6 | [Provider API v0.6.5](https://plas.redia.dk/en/provider/v0.6.5/) |
| Search API | Profile of Provider API — 8 of 54 operations | v0.6.5 | — | [Search API v0.6.5](https://plas.redia.dk/en/search/v0.6.5/) |
| Content API | Profile of Provider API — 4 of 54 operations | v0.6.5 | — | [Content API v0.6.5](https://plas.redia.dk/en/content/v0.6.5/) |
| Vendor Consumer API | Entry point | v0.6.5 | — | [Vendor API v0.6.5](https://plas.redia.dk/en/vendor/v0.6.5/) |

## How to read the table

- **In production** is the version providers implement and clients can rely on today. It is also the version the reference on this site is generated from.
- **In specification** is the version the PLAS team is working on. It is not released, and fields may change until it is.
- **Reference** points to the generated documentation of the production version.

If `PLAS Status` changes in Confluence, the copy in the repository is renewed as a deliberate act, and the table follows.

**One version number, four APIs.** The four APIs are released on the same number, and that is measured rather than assumed: Search and Content went from 0.6.4 to 0.6.5 without a single structural change — only the version number is new — while Vendor skipped 0.6.4 and went straight from 0.6.3 to 0.6.5, where its one new operation is exactly the one `PLAS Status` notes under v0.6.5.

## Older versions

Only the production version has generated pages. Older releases are still running at providers but have no reference here yet — their identifiers therefore appear without links. A reference URL, once published, keeps working, so older versions are added when the need is settled; they are not removed again.

## How to read a version

- **According to PLAS Status** is the source's text. Where the source itself writes "(Added) Patron API", it appears as markers in front of the line.
- **Changes to the specification** appear as one block per API. "Moved" means an operation changed method or path with the same `operationId`; if it got a new `operationId`, it appears as removed and added — that is what the specification says.
- **Zero changes is a result too.** A block saying nothing changed says the API got a new version number and otherwise stood still.
- Versions without a specification in the copy show only the source's text, and say so.

The filter above the list shows one API at a time. Without JavaScript, all four are shown.
