Added

• Chinese (Simplified) language, zh_CN. Thanks to CTfish0101.
• Every message and menu text accepts MiniMessage, such as <red>, <#5DB5F1> and <gradient:#5DB5F1:#FFFFFF>, alone or mixed with & codes. A new <smallcaps> tag writes small capitals. See the new Language Files page.
• Placeholder values, such as player and item names, can no longer add colours to a message.
• Chat messages can use <click> and <hover>. Menus, items, titles and holograms cannot, and a player or item name can never add a click to any text.
• language_auto_detect shows messages and menus in each player's own game language, when that language is installed.
• A GUI layout can have texts_<language>.yml next to its texts.yml for players in that language.
• A text missing from a language file now shows in English instead of a missing-key notice.
• Each GUI layout has a new filter_gui.yml to change the material of the middle column in the item filter menu.

Fixed

• Clicking an item in your own inventory while the item filter menu is open no longer adds it to the spawner's filter.
• Going back to storage from the item filter menu no longer moves your mouse cursor to the middle of the screen.
• Changing spawner_properties.default.delay now applies to spawners already placed, after /ss reload or a restart. Before, they kept the old delay until broken and placed again.
• Servers on an older Minecraft version no longer warn on every start about shipped spawner_mobs.yml entries for mobs that version does not have yet, such as sulfur_cube. Names added by hand are still checked.

Changed

• SmartSpawner now runs on Java 21 again, so Minecraft 1.21.11 servers no longer need Java 25. The ExcellentEconomy integration still needs Java 25, as ExcellentEconomy itself does.
• The shipped language files use MiniMessage instead of & codes. Edited texts keep their & codes and keep working.
• Only the active language and GUI layout are written to the plugin folder. Others are added the first time they are selected with /ss language or /ss gui_layout.
• Custom language folders now get key renames on update, like the built-in ones.
• Each language now has four files instead of eight, with keys grouped by menu and topic, and short comments. See the details below.
• The DonutSMP look is now chosen with gui_layout alone. The en_US_DonutSMP and en_US_DonutSMP_v2 languages were removed; their GUI text now comes with the DonutSMP and DonutSMP_v2 layouts, in a new texts.yml.
• A delay set with /ss set delay now stays on that spawner through reloads and restarts, instead of following the config.

Notes

• Servers using language: en_US_DonutSMP or en_US_DonutSMP_v2 are switched to en_US with the matching layout on the first start, and edited DonutSMP texts and messages are kept. The old language folders are saved in language.backup-<date>/. No action is required.
• Spawners given their own delay with /ss set delay before this version go back to the config delay once. Set it again where needed.
• Language folders, custom ones included, are converted to the new files on the first start. Edited texts are kept, and the old files are saved in language.backup-<date>/. No action is required.
