## What this fixes
The API changelog had a section header dated `2025-11-17`, but the
openapi.yaml version is `2025-10-17`. This was confusing because they
appeared to be tracking the same thing but didn't match.
## What happened
1. Various API changes (v0.1 introduction, endpoint removal) were made
in early-to-mid October
2. On **Oct 17**, commit 0828bc4 bumped the openapi.yaml version to
`2025-10-17`
3. These changes sat under an "Unreleased" section in the changelog
4. On **Nov 17**, commit 7b3f01a converted "Unreleased" → `2025-11-17`
as part of the v1.3.9 release process
The problem: `2025-11-17` was the date the release was cut, not the API
version. Since there were no openapi.yaml changes between Oct 17 and Nov
17, the changelog section should match the API version (`2025-10-17`),
not the internal release date.
## The fix
Change the changelog header from `## 2025-11-17` to `## 2025-10-17` to
align with the openapi.yaml version that consumers actually use.
@domdomegg am I correct in thinking this was just a typo? Or was the
distinction intentional?

Updates the API changelog to reflect the v1.3.9 release date
(2025-11-17).
This moves the 'Unreleased' section to a dated section as part of the
v1.3.9 release process.
<!-- Provide a brief summary of your changes -->
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
The following PR adds a new v0.1 API version.
The goal is to mark v0.1 as a "freeze" point while keeping v0 as the
moving target for new features so integrators can start building on top
of something stable(r).
Details:
* This change is quite simple - we re-register the same handlers twice,
once as `v0` and once as `v0.1`
* Going forward, we'll keep v0.1 frozen while we add changes either on
top of both (non-breaking) or we'll have to branch if breaking changes
are necessary
* We all acknowledge this is not exactly best-practice, but it gives us
a way to gather feedback and allow clients to start integrating with the
API without breaking them (**note** this implies a follow up PR that
would branch the handlers used in v0.1).
* For integrators/clients: please provide your feedback - what works
well, what doesn't so we can take this into account going towards GA.
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->
## Breaking Changes
<!-- Will users need to update their code or configurations? -->
No, this just adds a new API version alongside the existing one.
## Types of changes
<!-- What types of changes does your code introduce? Put an `x` in all
the boxes that apply: -->
- [ ] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
## Checklist
<!-- Go over all the following points, and put an `x` in all the boxes
that apply. -->
- [ ] I have read the [MCP
Documentation](https://modelcontextprotocol.io)
- [ ] My code follows the repository's style guidelines

Fixes: #649
Signed-off-by: Radoslav Dimitrov <radoslav@stacklok.com>
Remove redundant endpoint as suggested in #617. Clients should now use
`GET /v0/servers/{serverName}/versions/latest` instead (using `latest`
as a special version value in the existing endpoint).
This simplifies the API surface and reduces implementation burden for
subregistries, while maintaining a clear migration path for consumers.
## Changes
- Removed `GET /v0/servers/{serverName}` endpoint
- Updated `GET /v0/servers/{serverName}/versions/{version}` to accept
`latest` as special version
- Updated all tests to use new endpoint pattern
- Updated documentation and OpenAPI spec
- Added breaking change notice to CHANGELOG
Fixes#617
Co-authored-by: Claude <noreply@anthropic.com>
Wielded Claude Code to do this; across many iterations and have reviewed
all the code + largely rewritten the PR commentary here.
This PR implements the server ID consistency changes from
[#396](https://github.com/modelcontextprotocol/registry/issues/396). Our
goal is to:
- Rename `id` to `versionId` to make it clear that it is the ID for a
specific version, not a server
- Introduce `serverId` as a net new concept. This will be 1:1 with
`name`. While not strictly necessary (we could just use name as a PK),
the convention of having a UUID as an ID on our objects is just a
helpful subjective architecture decision. Plus also leaves open the door
to reconsidering the "should we allow renames" question.
## Key Changes
### 🗄️ Database Schema Changes
- **Renamed**: `id` column → `version_id` (unique identifier for each
server version)
### 📋 Metadata Structure Updates
- **JSON Schema**: Updated
`_meta.io.modelcontextprotocol.registry/official` to include:
- `serverId`: Consistent ID across all versions of a server
- `versionId`: Unique ID for this specific version (renamed from `id`)
### 🔧 API Endpoint Updates
- **New endpoint structure**: Changed from version-ID-based to
server-ID-based URLs:
- `GET /v0/servers/{server_id}` - Get latest version of server
- `GET /v0/servers/{server_id}?version=X.X.X` - Get specific version
- `GET /v0/servers/{server_id}/versions` - List all versions of a server
- `PUT /v0/servers/{server_id}?version=X.X.X` - Edit specific version
- **Consistent URL patterns**: All server endpoints now use `server_id`
as the primary identifier
### Database Migration Strategy
The migration (`005_add_server_id_rename_version_id.sql`):
1. Adds new `version_id` column
2. Generates deterministic UUIDs for servers with the same name
3. Updates JSON metadata to add `serverId` and rename `id` to
`versionId`
4. Copies existing `id` values to `version_id` column
5. Drops old `id` column and makes `version_id` the new primary key
## Testing
Besides of course automated tests passing, I:
1. Set up my local db with the pre-005-migration state, imported all the
production data
2. Ran the migration
3. Spot checked some diffs of the data that resulted --
