## Summary
Fixes staging deployment by renumbering migrations to match what staging
has already applied.
## Problem
Staging already applied migration 008 (metadata separation) before we
inserted the new cleanup migration. When we added the cleanup as 008 and
renumbered metadata to 009, staging tried to apply 009 again and failed
with "column already exists".
## Current State
- **Staging**: Has run original 008 (metadata separation), marked as
complete. Failed trying to run 009 (which is the same migration
renumbered).
- **Production**: Has not run either 008 or 009 yet.
## Solution
- Rename `008_clean_invalid_data.sql` → `007a_clean_invalid_data.sql`
- Rename `009_separate_official_metadata.sql` →
`008_separate_official_metadata.sql` (back to original)
## How This Fixes It
With this renumbering:
1. **Staging behavior**:
- Sees 008 is already complete (the metadata migration it already ran)
- Sees 007a as new and runs it, but it will be a no-op (skips because
staging doesn't have the problematic production data)
- Continues normally
2. **Production behavior**:
- Runs 007a (cleanup migration) - removes invalid data
- Runs 008 (metadata separation) - applies successfully because data is
now clean
- Both migrations run in the correct order as intended
## Testing
- Verified migration order works correctly
- Tested on empty database (test environment) - 007a skips as expected
- Tested with production data snapshot - 007a cleans data, 008 applies
successfully
This is a critical fix to unblock staging deployment.
## Summary
This PR adds two important improvements to ensure data integrity:
1. **Adds server name format validation at the API layer** to match the
database constraint from migration 008
2. **Includes migration 008 to clean up invalid data** before applying
strict constraints in migration 009
## Changes
### Server Name Validation
- Enforces validation at the API layer matching the database constraint
- **Namespace pattern**: `[a-zA-Z0-9][a-zA-Z0-9.-]*[a-zA-Z0-9]`
- Must start and end with alphanumeric characters
- Can contain dots and hyphens in the middle
- **Name pattern**: `[a-zA-Z0-9][a-zA-Z0-9._-]*[a-zA-Z0-9]`
- Must start and end with alphanumeric characters
- Can contain dots, underscores, and hyphens in the middle
- Provides clear, user-friendly error messages indicating which part is
invalid
- Uses DRY approach with composed regex patterns
### Migration 008: Data Cleanup
- Removes servers with invalid names or empty versions (5 servers
affected in production)
- Fixes invalid status values by setting them to 'active' (1 server
affected)
- Removes duplicate name+version combinations
- Includes comprehensive safety checks to prevent accidental data loss
- Must run before migration 009 which adds strict constraints
## Testing
- All validator tests pass
- Migration includes safety checks that match production data
- CI verification included

## Summary
- Fixes migration 008 failing with "column contains null values" error
- Adds COALESCE protection to handle 126 servers without status fields
- Includes test utilities to reproduce and verify fixes with production
data
## Problem
Migration 008 was failing in production because:
- 126 out of 781 servers have no `status` field in their JSON
- When extracting `rec.value->>'status'`, these became NULL values
- The `ALTER TABLE servers ALTER COLUMN status SET NOT NULL` constraint
then failed
## Solution
1. **Prevent NULLs during migration**: Use COALESCE to provide 'active'
default when status is NULL/empty
2. **Enhanced debugging**: Added RAISE NOTICE statements to log
problematic values
3. **Safety check**: Double-check that throws exception if any NULLs
remain
4. **Test utilities**: Created mirror_data tools to test migrations with
real production data
## Testing
Created and used `scripts/mirror_data/` tools to:
- Fetch all 781 servers from production API
- Load them into a test database
- Verify the migration fix works correctly
### Results:
- **Before fix**: 126 NULL status values created during migration
- **After fix**: 0 NULL status values, all servers have valid status
- Migration completes successfully with NOT NULL constraint
## Test plan
- [x] Tested locally with production data using mirror_data tools
- [x] Verified 0 NULL values after migration (vs 126 before)
- [x] Confirmed NOT NULL constraint adds successfully
- [ ] Deploy to staging and verify migration succeeds
- [ ] Monitor production deployment

## Problem
Production deployment is failing with CrashLoopBackOff. Migration 008
fails with:
```
ERROR: column "status" of relation "servers" contains null values (SQLSTATE 23502)
```
## Root Cause
The migration extracts the `status` field from an unexpected location in
the data structure.
### Actual Data Structure (Before Migration)
In the current format, `status` is at the **top level** of the JSON, not
nested in official metadata:
```json
{
"name": "com.example/server",
"version": "1.0.0",
"status": "active", ← STATUS IS HERE (top level)
"_meta": {
"io.modelcontextprotocol.registry/official": {
"serverId": "uuid",
"publishedAt": "2025-09-01T00:00:00Z",
"isLatest": true
// NO STATUS FIELD HERE
}
}
}
```
For 120 out of 765 servers, the status field is **missing entirely**:
```json
{
"name": "com.biodnd/agent-ip",
"version": "0.1.2",
// ← NO STATUS FIELD AT ALL
"_meta": {
"io.modelcontextprotocol.registry/official": {
"serverId": "uuid",
"publishedAt": "2025-09-23T09:47:07Z",
"isLatest": true
// STILL NO STATUS FIELD HERE
}
}
}
```
### Original Migration Logic
```sql
IF official_meta IS NOT NULL THEN
UPDATE servers
SET
status = (official_meta->>'status'), -- Extracts NULL for all servers
```
**Result:**
- All 765 servers would have NULL status extracted
- Because `official_meta->>'status'` returns NULL (field doesn't exist
there)
- The migration tries to add `NOT NULL` constraint → fails
### Fixed Migration Logic
```sql
IF official_meta IS NOT NULL THEN
UPDATE servers
SET
status = COALESCE(NULLIF(rec.value->>'status', 'null'), 'active'),
```
**Result:**
- Extracts from top-level JSON where status actually exists
- `NULLIF(rec.value->>'status', 'null')` handles edge case of literal
string "null"
- `COALESCE(..., 'active')` provides fallback when status is missing
- All servers get valid status value
### Impact Breakdown
**645 servers with `"status": "active"`:**
- Before fix: Would extract NULL → migration fails
- After fix: Extracts "active" correctly
**120 servers with missing status field:**
- Before fix: Would extract NULL → migration fails
- After fix: Defaults to 'active' via COALESCE
## Example Servers with Missing Status
(First 9 discovered during investigation)
- com.biodnd/agent-ip
- io.github.jkakar/cookwith-mcp
- com.joelverhagen.mcp/Knapcode.SampleMcpServer
- io.github.Lyellr88/marm-mcp-server
- com.biodnd/agent-press
- io.github.timheuer/sampledotnetmcpserver
- io.github.CodeCraftersLLC/local-voice-mcp
- com.biodnd/agent-fin
- io.github.ruvnet/ruv-swarm
## Testing
Verified against production data (765 total servers):
- ✅ All servers have official metadata
- ✅ None have status in official metadata (expected)
- ✅ 645 have "status": "active" at top level
- ✅ 120 have missing status field (no field present)
- ✅ Fix extracts from correct location for all cases
## Impact
This unblocks production deployment. Once merged and released as v1.2.1,
the migration will:
1. Extract status from the correct location (top-level JSON)
2. Handle missing status fields with sensible defaults
3. Successfully add NOT NULL constraint
4. Allow pods to start normally

## Motivation and Context
Currently the `dns` and `http` based auth flows share code well in the
publisher tool. However there is a lot of duplication in the auth
endpoint. This on it's own is not a problem but it does make
enhancements to the proof record (the `v=MCPv1; ...` string) harder to
keep in sync.
This PR adds a `common.go` file to share logic between the two.
This supports work I am prototyping for
https://github.com/modelcontextprotocol/registry/issues/482.
## How Has This Been Tested?
Added new test cases for the permissions. Ran them before and after the
refactoring to ensure no behavior change.
Ran existing UTs.
Ran the integration tests.
Manually exercised the flows locally.
## Breaking Changes
None.

Add three new community projects to the community-projects.md reference:
- mcp-registry-cli: CLI tool for navigating registry servers
- mcp-insights: Analytics and insights platform
- Open Chat MCP Registry Client: TypeScript client implementation
## Summary
- Remove the `status` field from all server.json examples in
documentation
- Remove the deprecated server example that was primarily about
demonstrating the status field
- Update example count validation from 13 to 12
## Context
The `status` field was removed from the server.json schema in commit
b21c6f5 (#562). This PR cleans up the documentation to reflect that
change.
## Why didn't tests catch this?
The schema validation didn't catch the invalid `status` field because
the JSON schema doesn't have `additionalProperties: false` set. This
means the schema allows arbitrary additional properties by default.
## Test plan
- [x] All validation checks pass (`make check`)
- [x] Example count updated to match the new total (12 examples)

## Summary
Add Community Resources section to GitHub Actions guide referencing
OtherVibes/mcp-publish-action as requested in discussion #518.
## Changes
- Add "Community Resources" section to
`docs/guides/publishing/github-actions.md`
- Include reference to OtherVibes/mcp-publish-action with appropriate
disclaimers
- Provide example usage and key features
- Position after Tips section for discoverability
- Structure allows for future community tool additions
## Context
This addresses the community request in discussion #518 where
@OtherVibes suggested adding a reference to their reusable GitHub Action
in the publishing docs. The maintainers (@tadasant, @domdomegg) approved
adding a community resources section with appropriate disclaimers.
The implementation follows the original request to add the reference
specifically to the GitHub Actions guide
(`docs/guides/publishing/github-actions.md`) rather than creating a
separate page.
## Benefits
- Provides users with a streamlined, community-built option for MCP
server publishing
- Reduces workflow boilerplate for developers
- Includes clear disclaimers about third-party tools
- Maintains documentation cohesion by keeping everything in the relevant
file
Closes#518

This pull request makes a minor update to the documentation for
installing the MCP Publisher in GitHub Actions workflows. The change
updates the installation command to use version 1.1.0 of the MCP
Publisher instead of version 1.0.0.
## Motivation and Context
The `mcp-publisher` version in GitHub Actions has to be updated so it
can publish the MCP server to the newest version of MCP Registry.
## How Has This Been Tested?
Documentation update only. No test needed.
## Breaking Changes
No
## Types of changes
- [ ] 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)

## Motivation and Context
Replace server-only `http.MaxBytesReader(nil, ...)` with
`io.LimitReader` to cap the fetched body to 4KB in key fetcher. This
avoids passing a `nil` ResponseWriter and aligns with Go idioms. If more
than 4KB is received, return a clear error. Previously `MaxBytesReader`
returned a misleading `http: request body too large` error, which is
server-oriented. With this change the error becomes `HTTP auth key
response too large`.
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->
Add tests covering success, oversized bodies, connection failure,
non-200 status, and read failures. This covers almost all lines of
`FetchKey` method of `DefaultHTTPKeyFetcher`. For tests, I also added a
new initialiser `NewDefaultHTTPKeyFetcherWithClient` so that the HTTP
client could be modified for test use.
Tests use `httptest.NewTLSServer` plus a helper to construct a client
pinned to the test server.
`auth` package test coverage increased from 56.8% to 59.3%.

<!-- Provide a brief summary of your changes -->
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
The following PR updates production to automatically receive new stable
releases when GitHub releases are cut while staging will continue
testing the latest main branch builds
Deails:
- Configures production deployment to **use latest stable** releases
instead of main branch
-`ghcr.io/modelcontextprotocol/registry:latest`(stable releases).
Released CLI matches version of the prod service API.
- Staging continues to **use main branch** for testing latest
development code - `ghcr.io/modelcontextprotocol/registry:main` (latest
development). Building the CLI from main would match the version of the
staging service API.
- Added environment-based Docker image tag selection logic

## Summary
Fixes a race condition where a server could have no version marked as
`isLatest` if the database operations failed independently.
## Changes
- **CreateServer signature**: Now accepts `oldLatestVersionID` parameter
to atomically unmark previous latest version
- **PostgreSQL implementation**: Uses a transaction to ensure UPDATE
(unmark old latest) and INSERT (create new version) happen atomically
- **Service layer**: Maintains `WithPublishLock` for concurrent
operation serialization
- **Two-level protection**: Advisory lock prevents races, transaction
ensures atomicity
## Test plan
- [x] Existing race condition tests pass
- [x] Integration tests pass
- [x] Unit tests pass

<!-- Provide a brief summary of your changes -->
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
The follow PR removes the in-memory database option from the registry.
We had a chat about this with @domdomegg and although it is supposed to
be convenient, it isn't that useful in reality. We want to test and
develop the registry in a setup that is closer to the environment it is
supposed to be run. One of the main reasons are:
* We don't use it anywhere else besides unit testing and potentially
local development. Instead we should use postgresql for reliable results
(in-memory was actually giving false positive results)
* We have to keep maintaining it and make sure it mimics the behaviour
we have for postgresql which is not yielding a lot of value
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->
Yes, I've updated the test unit make target to run in the postgresql
environment and now we can see the race condition issue happening.

## Summary
Fixes a concurrent map access vulnerability in the OIDC handler that
could cause remote unauthenticated DoS.
## Changes
- Removed OIDC authorization flow endpoints ( and )
- Removed the unsynchronized map that caused the data race
- Kept only the OIDC token exchange endpoint ()
- Simplified by removing OAuth2 flow dependencies
The map was being accessed concurrently by the start (write) and
callback (read/delete) endpoints without synchronization, causing
runtime panics. Since the token exchange flow doesn't require session
state, removing the authorization flow eliminates the vulnerability
entirely.
## Summary
Fixes race conditions in concurrent server publishing that could result
in data integrity violations:
- Multiple versions marked as `isLatest=true` for the same server
- Duplicate (serverId, version) combinations
- Same server name assigned different serverIDs
## Solution
Uses two complementary approaches for correctness:
### 1. PostgreSQL Advisory Locks
- Serializes concurrent publishes per server name using
`pg_advisory_xact_lock`
- Uses FNV-1a hash to convert server name to lock ID
- Transaction-scoped locks auto-release on commit/rollback
- **Required after #465**: The serverId introduction means concurrent
publishes must atomically coordinate whether to reuse an existing
serverId (for additional versions) or generate a new one (for first
version). Without locks, race conditions would assign different
serverIDs to versions of the same server.
### 2. Unique Constraints (Migration 007)
Two new indexes provide data integrity guarantees:
- **idx_unique_server_version**: Ensures (serverId, version) is unique
across all versions
- **idx_unique_latest_version**: Partial index ensuring only one version
per serverId has `isLatest=true`
These constraints serve as defense-in-depth safety nets. Even if lock
logic had a bug, the database would reject integrity violations.
Also drops redundant `idx_servers_version_id` since `version_id` is
already the primary key.
## Why WithPublishLock validation is needed after #465
The `ctx.Err()` check at the start of `WithPublishLock` is critical
because:
1. After #465 introduced serverId, the publish flow must atomically
check existing versions and assign/reuse serverId
2. If the context is cancelled during lock acquisition, we could
deadlock
3. Checking ctx validity before acquiring locks prevents these deadlocks
## Testing
Added `TestPublishConcurrentVersionsNoRace` with 100 concurrent
goroutines publishing different versions of the same server. All succeed
with:
- Exactly one version marked as latest
- All versions sharing the same serverId
- No duplicate (serverId, version) combinations
NB: this only covers the in memory db, not the postgres db. It'd be nice
to write tests for this one as well, but our current setup is a bit
annoying for this. Separately looking into ways to easily run all our
tests with real postgres and ideally scrap memory.go completely.
## Motivation and Context
- Make all entries in current database matching the new schema

- locally

- Yes

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 --
```json

## Summary
- Fixed `Remote` schema in OpenAPI spec to use correct field name `type`
instead of `transport_type`
- Updated enum values from `[streamable, sse]` to `[streamable-http,
sse]` to match actual API
## Context
The OpenAPI spec was inconsistent with the actual API implementation.
The live API at https://registry.modelcontextprotocol.io/v0/servers
returns `type: 'sse'` and `type: 'streamable-http'`, but the spec
defined `transport_type` with values `streamable` and `sse`.
This now matches:
- The Go constants in pkg/model/constants.go
- The actual API responses
## Summary
Bumps the node machine type from e2-small to e2-standard-2 to provide
more CPU and memory headroom for the cluster.
Also disables PodDisruptionBudgets (PDBs) for single-instance PostgreSQL
clusters to prevent node upgrade operations from becoming blocked.
## Changes
- Increase GKE node machine type from e2-small to e2-standard-2
- Set `enablePDB: false` for registry and Grafana PostgreSQL clusters
## Context
The machine type increase addresses resource constraints causing
deployment failures.
The PDB change prevents a specific issue where GKE node upgrades get
stuck when trying to drain nodes containing single-instance PostgreSQL
pods. With `minAvailable: 1` PDBs, evicting the only database instance
violates the availability requirement, blocking the drain operation
indefinitely. Disabling PDBs for these development/staging
single-instance databases allows node maintenance to proceed smoothly.
For production deployments requiring high availability, the instances
count should be increased to 3 with PDBs enabled.

This commit implements support for publishing MCP servers to GitHub
Container
Registry (ghcr.io) in addition to the existing Docker Hub support,
addressing
Docker Hub rate limiting concerns as requested in #393.
Key changes:
- Add RegistryURLGHCR constant for https://ghcr.io
- Refactor OCI validation to support multiple container registries with
extensible RegistryConfig system
- Implement registry-agnostic authentication system that handles:
- Docker Hub token-based authentication via auth.docker.io
- GHCR token-based authentication via ghcr.io/token service
- Update Accept headers to support OCI image indexes for multi-arch
images
- Extract helper functions to reduce cyclomatic complexity and improve
code maintainability
- Add comprehensive test coverage for both Docker Hub and GHCR scenarios
- Include real image testing with github/github-mcp-server and
nkapila6/mcp-local-rag
- Update publishing documentation with GHCR examples and authentication
details
The implementation maintains backward compatibility with existing Docker
Hub
usage while providing a future-proof architecture for adding additional
container registries. All authentication is now handled through proper
token
services for both registries.
Fixes#393
## Motivation and Context
Docker Hub rate limiting has been causing issues for the MCP registry
when validating OCI images. Adding GHCR support provides an alternative
container registry that many MCP server authors are already using,
reducing the load on Docker Hub and providing more options for the
community.
## How Has This Been Tested?
- All existing unit tests continue to pass
- Added comprehensive test coverage for GHCR scenarios including:
- Non-existent images (proper error handling)
- Real images without MCP annotations (github/github-mcp-server)
- Real images with proper MCP annotations (nkapila6/mcp-local-rag)
- Registry URL validation for both supported registries
- Tested authentication flow manually using curl commands
- Verified multi-arch image support with OCI index manifests
## Breaking Changes
None. This is a purely additive change that maintains full backward
compatibility with existing Docker Hub configurations.
## Types of changes
- [x] New feature (non-breaking change which adds functionality)
- [x] Documentation update
## Checklist
- [x] I have read the [MCP
Documentation](https://modelcontextprotocol.io)
- [x] My code follows the repository's style guidelines
- [x] New and existing tests pass locally
- [x] I have added appropriate error handling
- [x] I have added or updated documentation as needed
## Additional context
The implementation uses a RegistryConfig struct to abstract
registry-specific details like API endpoints, authentication URLs, and
token services. This design makes it straightforward to add support for
additional container registries in the future (such as AWS ECR, Azure
Container Registry, etc.) by simply adding new cases to the
getRegistryConfig function.
The authentication system properly handles the different token services
used by each registry:
- Docker Hub: auth.docker.io with service=registry.docker.io
- GHCR: ghcr.io/token with service=ghcr.io
Both registries now support the full OCI specification including
multi-arch images via OCI image indexes.
<!-- Provide a brief summary of your changes -->
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
NuGet package deployment option is mentioned in the
[guidelines](https://github.com/modelcontextprotocol/registry/blob/main/docs/guides/publishing/publish-server.md#configure-deployment-methods)
for publishing MCP Server to the registry, but `NuGet` is not mentioned
in the top of the page.

## Summary
Added validation to reject server names with multiple slashes, ensuring
consistency between JSON schema pattern and API validation.
- Count slashes in parseServerName() and reject if > 1
- Add ErrMultipleSlashesInServerName error constant
- Add unit tests in validators_test.go
- Add integration test in publish_test.go
## Motivation and Context
Fixes#471. The JSON schema regex pattern `^[^/]+/[^/]+$` only allows a
single slash in server names, but the API validation was not enforcing
this constraint. This inconsistency
allowed invalid server names like `com.example/server/path` to be
published.
## How Has This Been Tested?
- Unit tests added to verify slash validation logic
- Integration tests added to verify the publish endpoint rejects
multi-slash names
- Tested various edge cases: trailing slashes, consecutive slashes,
URL-like paths
- All existing tests pass
## Breaking Changes
None. This change only adds validation to reject previously invalid
server names that shouldn't have been accepted.
## Types of changes
- [x] 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
- [x] I have read the [MCP
Documentation](https://modelcontextprotocol.io)
- [x] My code follows the repository's style guidelines
- [x] New and existing tests pass locally
- [x] I have added appropriate error handling
- [x] I have added or updated documentation as needed
## Additional context
- The fix ensures server names follow the intended format:
`namespace/name` (e.g., `com.example/my-server`)
- This validation aligns the API behavior with the existing JSON schema
regex pattern
- Test coverage includes edge cases like `com.example//server`,
`com.example/server/`, and `a/b/c/d/e/f`
- The error message clearly indicates the issue: "server name cannot
contain multiple slashes"

## Summary
- Removes version comment tags (e.g. `#v4`, `#v5`) from all GitHub
Actions workflow files
- These tags become incorrect when Dependabot updates the action SHAs
- The SHA pins are sufficient for version control
## Context
This addresses @domdomegg's comment in #453 about these tags becoming
outdated when using Dependabot. The SHAs already provide version
pinning, making the comment tags redundant and potentially misleading.
## Changes
- Removed version tags from all `uses:` statements in
`.github/workflows/*.yml`
- No functional changes to workflows
<!-- Provide a brief summary of your changes -->
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
The following PR:
* Bumps Go to the latest stable version
* Moves away from setting the Go version as an env var in favour of
reading it automatically from the go.mod file (better consistency)
Closes: #447
