+## Version 2.0.0-alpha.24
+
+### Features
+
+- Added `FactorioIcon` component for showing icons from the game in the web UI. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Added `useDefaultModPack` hook to the web UI. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Added types for the exported metadata for mod packs. [#526](https://github.com/clusterio/clusterio/issues/526)
+- Added config value validation beyond simple type checks. [#856](https://github.com/clusterio/clusterio/pull/856)
+- Added config staging to allow setting many values at once. [#856](https://github.com/clusterio/clusterio/pull/856)
+- Added a warning when attempting to set player autosave slots lower than autosave slots. [#855](https://github.com/clusterio/clusterio/issues/855)
+- Added `controller.authSecret` as the type of config field `controller.auth_secret` was inconsistent. [#856](https://github.com/clusterio/clusterio/pull/856)
+- Added support for the `node:` prefix in import statements in web UI code. [#881](https://github.com/clusterio/clusterio/pull/881)
+- Added config validation to load plugin to error when save patching or script commands are disabled [#884](https://github.com/clusterio/clusterio/issues/884)
+
+### Fixes
+
+- Fixed host printing a deprecation warning on startup. [#855](https://github.com/clusterio/clusterio/issues/855)
+- Fixed exported prototype metadata missing localised_name. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Fixed headless download option in installer failing with `TypeError: callback is not a function`. [#860](https://github.com/clusterio/clusterio/issues/860)
+- Fixed controller crashing if a host attempted to download a mod that had been deleted from the controller's filesystem while the controller was running. [#860](https://github.com/clusterio/clusterio/issues/860)
+
+### Changes
+
+- Moved `/icon-reference` to `/mods/mod-packs/:id/icon-reference` and linked it from the mod pack page. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Made the `useAccount`, `useModPacks`, `useMods`, `useRoles`, `useSaves`, `useSystems`, `useUsers` and related hooks in the web UI available to plugins. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Exported prototypes are now based on the `defines.prototypes` mapping from the game. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Removed usage of fs-extra. [#860](https://github.com/clusterio/clusterio/issues/860)
+
+### Breaking Changes
+
+- Removed `useExportManifest` from the web UI. Use `.exportManifest` on a mod pack from one of the `useModPack` hooks instead. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Replaced the 8 `useTypeMetadata` hooks in the web UI such as `useItemMetadata` with `useExportPrototypeMetadata`. [#875](https://github.com/clusterio/clusterio/pull/875)
+- `.item-name` css classes are no longer created in the web UI, and will not render icons from the game. Use the `FactorioIcon` component instead and pass it a prototype from `useExportPrototypeMetadata`. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Renamed `useLocale` hook in web UI to `useExportLocale` which now requires the mod pack to load the exported locale from as an argument. [#875](https://github.com/clusterio/clusterio/pull/875)
+- Fluids are no longer merged with items in the exported prototype metadata for mod packs. [#875](https://github.com/clusterio/clusterio/pull/875)

Hornwitser	0d28a3ac3c	Refactor web_ui handling of exports The handling of exported data such as locales and icons in web_ui was based on a model where there is only one set of data exported per cluster. This model changed to have one set of exports per mod pack when mod packs were introduced, but the existing web_ui code was bodged to use exports from a "default mod pack" on the controller. Refactor the code loading exported data to take the mod pack as an argument for selecting which exported data to load. The different kinds of prototype metadata that can be loaded is consolidated into one `useExportPrototypeMetadata` hook. The logic for displaying icons is put into a `FactorioIcon` component. And the obsolete `useExportManifest` hook is removed. These changes allow the `/icon-reference` page to display exports on a per mod pack basis. Which has now been linked on the bottom of the mod pack view page.	2026-03-16 17:11:47 +01:00

Hornwitser	433cc3c712	Add missing model exports to web_ui package A lot of the models were not available to plugins due to the index page not exposing them on the package.	2026-03-13 18:33:57 +01:00
Hornwitser	ab5162e581	Add changelog script parsing entries from PRs (#871 ) Add script which uses GitHub's REST API to fetch issues and pull requests that have changed since the last release, parse out the changelog entries from merged pull requests, and print a formatted version of the changelog suitable for copying into the release description, the CHANGELOG.md file and the Discord announcement. The script expects Pull Requests to have a `### Changelog` section in them with a code block containing changelog entries. As an added bonus the script can parse out `#<number>` references so that you do not need to write it out in the ugly `[#id](long-url-with-id-repeated)` format. Updates documentation and pull request template to describe the changelog format and usage of the formatting script. Includes improvements from review and a second look.	2026-03-13 15:33:24 +01:00
Hornwitser	3b8058de81	Refactor icon export to be based on prototypes Use the defines.prototypes data structure from the game to find which prototype sub-types belong in the same base type, and export icons based on these base type. This renames the planets category to space-location, signal to virtual-signal and plits item up into item and fluid. And changes the exported metadata to include prototypes with no icons, as future code might want to use it to for example enumerate all item prototypes.	2026-03-12 18:26:04 +01:00
