Versionsverlauf von [`jpkcom-simple-lang`](https://github.com/JPKCom/jpkcom-simple-lang). Die Einträge stammen unverändert aus der README des Projekts. Eine ausführliche Anleitung mit Tipps findest du im [Projekt-Guide](https://www.jpkc.com/db/guides/jpkcom-simple-lang/).

## 1.2.3 - 2026-06-16
* Raised the minimum WordPress version to 6.9 and "Tested up to" to WordPress 7.0
* Switched license metadata to the SPDX identifier `GPL-2.0-or-later` with the HTTPS license URI

## 1.2.2 - 2026-06-16
* Security: updater prefers an exact match against the manifest `download_url` over the slug heuristic, so a tampered manifest can no longer bypass the checksum gate
* Security: timing-safe checksum comparison (`hash_equals()`) with an `is_string()` guard against `hash_file()` failures
* Security: manifest fetch via `wp_safe_remote_get()` (SSRF defense-in-depth)
* Fixed PHP warning and missing contributor names in the plugin detail popup (`display_name` now provided)
* Fixed PHP warning/deprecation on `wp plugin list` by completing the `no_update` transient entry (`new_version`, `package`, `tested`, `requires_php`)

## 1.2.1 - 2026-03-13

**Bug Fixes**

- Fixed manual ZIP upload failing with "No valid URL" error caused by checksum verification running on local file paths instead of remote URLs

**Bug Fixes**

- Fixed language selection not saving for locales without country code (e.g. `ar` for Arabic)

- Added German translations for Oxygen condition options (Ja/Nein)
- All Oxygen conditions now appear under "Simple Lang" category

**Technical Changes**

  - `jpkcom_simplelang_oxygen_has_custom_language()` with ($value, $operator) parameters
  - `jpkcom_simplelang_oxygen_uses_default_language()` with ($value, $operator) parameters
