# Gitea Compatibility
This document tracks the compatibility between **Gitea Mail Templates** releases and **Gitea** versions.
## Quick Reference
<!-- TRACKER:QUICK-REF-MAX OFFSET=3 -->
| Template Release | Min Gitea | Max Tested Gitea | Status |
|-----------------|-----------|-----------------|--------|
| **main (unreleased)** | **1.25.0** | **1.27.3** | ✅ Fix pushed and verified; release pending |
| **v1.27.2** | **1.25.0** | **1.27.3** | ⚠️ Push notices fail in Bloom, Ember, and Heritage on Gitea 1.27.1+ |
| **v1.0.1** | **1.25.0** | **1.27.0** | ✅ Superseded; push notices need newer release on 1.27.1+ |
| **v1.0.0** | **1.25.0** | **1.26.4** | ✅ Superseded |
> **Latest verified:** The fix on `main` passes the Gitea 1.27.3 source audit and push-render test; [CI passed](https://github.com/KenanZhu/GiteaMailTemplates/actions/runs/35824718700). The published v1.27.2 archive still contains three broken push-notification templates. <!-- TRACKER:LATEST-VERIFIED -->
## Versioning
The release tag identifies the downloadable template package. The supported Gitea version may be appended in parentheses in this compatibility matrix; the parenthesized version is not a Git tag. A **main (unreleased)** row describes fixes available in the repository but not yet in a downloadable release.
| Gitea version | Template release |
|---------------|------------------|
| 1.27.3 | **main (unreleased)**; published v1.27.2 has a push-notification issue in three themes |
| 1.27.2 | **main (unreleased)**; published v1.27.2 has the same issue |
| 1.27.1 | **main (unreleased)**; published v1.27.2 has the same issue |
- The [tracker workflow](.github/workflows/gitea-tracker.yml) opens a PR when a new Gitea release appears, marking it ⏳ Pending Verification.
- After verification, update the top **Template Release** row. Keep fixes on `main` marked **unreleased** until a new tag is published; the [release workflow](.github/workflows/release.yml) packages the archive on tag push.
- The older `v1.0.1` tag predates the Gitea 1.27.1 push notification data fix and should not be used for Gitea 1.27.1 or newer.
## Check Your Gitea Version
```bash
# On your Gitea server:
gitea --version
# Or check the web UI footer / Site Administration → Monitoring
```

### Translation Keys
All templates use Gitea's official `mail.*` translation namespace. Keys are stable across Gitea 1.25+.
## How Compatibility Is Verified
1. **Automated lint** — CI renders all templates via `go run . preview all` on every push
2. **Source audit** — Template data contexts are cross-referenced against Gitea's `services/mailer/` package
3. **Release checklist** — Each release confirms the max-tested Gitea version in this file
## Automated Tracking
A [workflow](.github/workflows/gitea-tracker.yml) runs daily (UTC 08:00) to detect new Gitea releases. When a new version is found, it automatically creates a PR updating the matrix and badges with a **⏳ Pending Verification** status. Manual trigger is also available via `workflow_dispatch`. Once verification passes, update the compatibility matrix; publish a new template tag when template changes require a release (see [Versioning](#versioning)).
## Reporting Issues
If you find a compatibility problem with a specific Gitea version:
1. Check the [Gitea changelog](https://github.com/go-gitea/gitea/blob/main/CHANGELOG.md) for recent mail template changes
2. Open an issue with: your Gitea version, which template, and the error
