Part of the plugin API contract work.

Plugins can declare which plugin api version they target so the panel can refuse to load plugins written against a future incompatible api instead of failing unpredictably. The field is optional and defaults to 1. Plugins declaring a higher version than the panel supports are marked incompatible before loading using the same status flow as the panel_version check, plugins missing the field get a warning note under their status badge on the plugins page, and p:plugin:make scaffolds the field.

Walkthrough

The panel now reads plugin API versions from plugin.json, defaults missing values to version 1, and evaluates compatibility. Generated plugins include the supported API version. Production loading enforces compatibility, and the admin interface warns when the field is missing.

Changes

Plugin API compatibility

Layer / File(s) Summary
API version contract and validation
app/Models/Plugin.php, tests/Unit/Models/PluginApiVersionTest.php
Plugin defines supported API version 1, reads api_version, defaults missing values to 1, and evaluates compatibility. Tests cover supported, missing, and newer versions.
Generated plugin metadata
app/Console/Commands/Plugin/MakePluginCommand.php
The command uses SoftwareVersionService for the panel version prompt and writes api_version set to Plugin::SUPPORTED_API_VERSION into generated plugin.json files.
Plugin loading and admin status
app/Services/Helpers/PluginService.php, app/Filament/Admin/Resources/Plugins/PluginResource.php, lang/en/admin/plugin.php
Production loading marks unsupported plugins as incompatible and skips them. The admin status display warns when api_version is missing.

The implementation appears correct, but a focused loader test is needed to prevent future regressions that could load incompatible plugins in production.

Why do we need both a panel_version and a api_version? A specific panel version contraint also implies a specific api version constraint.

Why do we need both a panel_version and a api_version? A specific panel version contraint also implies a specific api version constraint.

panel_version only works in one direction. It can say "this plugin needs panel 1.6 or newer". It cannot say "this plugin stops working after panel X", because the plugin author does not know which future panel version will break the plugin API.

Example: a plugin says panel_version: ^1.2. Later, panel 1.9 changes the plugin API in a breaking way. The old check still passes (1.9 is newer than 1.2), so the panel loads the plugin and it crashes. With api_version, the panel sees the plugin was built for API 1, knows it now uses API 2, and can refuse to load it with a clear message instead.

Also, panel versions change all the time (features, bug fixes). The API version only changes when the plugin API actually breaks. Paper/Bukkit does the same thing: plugins declare api-version separately from the server version.

Thinking about it, this check should only be executed in production env. This way plugin developers in a local env can work on their plugin/fix it for the current api version.

🟡 Minor · Cover the production loader boundary.

app/Services/Helpers/PluginService.php:40-50
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Cover the production loader boundary. PluginApiVersionTest only checks Plugin::effectiveApiVersion() and Plugin::isApiVersionSupported(). It does not reach PluginService::loadPlugins(), which AppServiceProvider::register() calls during startup. Add an integration test that bypasses the loader’s runningUnitTests() guard, reports production, and supplies a plugin with a future api_version. Assert that the plugin receives PluginStatus::Incompatible and that a sentinel provider or other loading side effect is not registered. The gate must stop execution before provider registration at PluginService.php:47-50 and 101-108.
