 ## Compatibility
 
-- **Gitea 1.25+** — matches the refactored mail template directory structure (v1.25)
-- **Latest tested:** Gitea 1.27.3 <!-- TRACKER:LATEST-TESTED -->
-- **Latest release:** [v1.27.3](https://github.com/KenanZhu/GiteaMailTemplates/releases/tag/v1.27.3) fixes push notifications in Bloom, Ember, and Heritage on Gitea 1.27.1+. The older v1.27.2 archive is affected (see [COMPATIBILITY.md](COMPATIBILITY.md))
+- **Gitea 28.0.0** — use template release v28.0.0; earlier Gitea versions require an older package
+- **Latest tested:** Gitea 28.0.0 <!-- TRACKER:LATEST-TESTED -->
+- **Latest release:** [v28.0.0](https://github.com/KenanZhu/GiteaMailTemplates/releases/tag/v28.0.0) updates all 10 release-notification templates for Gitea's `FormatByteSize` function. Use [v1.27.3](https://github.com/KenanZhu/GiteaMailTemplates/releases/tag/v1.27.3) for Gitea 1.25.0–1.27.3 (see [COMPATIBILITY.md](COMPATIBILITY.md))
 - The current source uses Gitea's official template data paths — see [COMPATIBILITY.md](COMPATIBILITY.md) for release-specific limitations
 - Uses only built-in Gitea template functions and official translation keys
 - No custom template functions or locale patches required
