What's new

Richer validation

Define validation rules per field directly in the PlantUML diagram, e.g.:

• teaser: string {maxLength: 140}
• code: string {minLength: 3} {maxLength: 12}
• zip: string {pattern: plz}
• servings: int {min: 1, max: 20}

• publishedAt: date {min: 2020-01-01}

• Length limits (minLength/maxLength) for string, text and richtext. Lengths are counted in Unicode characters; for richtext only the visible text counts.

• Value ranges (min/max) for int, decimal and date.
• Pattern library in the admin area (Settings → Patterns): reusable regular expressions with an editor-facing error message and an example value. Built-in patterns: email, url, slug, plz.
• Enforced server-side for every write path: POST, PUT, the new PATCH route, the editing form, version restore and the test data generator.
• ReDoS protection: expensive expressions are rejected on save, and in-browser checks run in a Web Worker with a time limit.
• Tightened rules never modify existing data. Schema analysis reports how many records would be affected, and a new Rule violations view lists them with direct links for manual cleanup.
• Character counter and inline errors in the editing form.

Languages and translations

• All server messages are now in English and carry a code and params, so API clients can translate them. The editing interface translates via these codes, so German users see the same texts as before.
• One consistent fallback chain for UI texts and server messages: display language → default language → English.
• English works out of the box: shipped language files (currently en.csv) take effect without an import.
• Custom language files: set CUSTOM_TRANSLATIONS_DIR in config.php to use your own translation files. That folder is not touched by updates.
• Fixed UI texts can now be translated or overridden for the default language too, e.g. for a fully French installation.

Bug fixes

• After login, a route selected quickly (sidebar click or typed URL) was overwritten by the start page redirect.
• The rich text editor could steal focus while UI texts were still loading, so typed input ended up in the wrong field.

⚠️ Breaking change for API clients

Error messages in message, errors and violations are now English. If your client displays them, switch to code / error_codes and params. See REST API docs.

Upgrading

No schema migration needed. New system tables are created automatically on first access.
