OpenJavascript

General Fixes & Improvements

• Scripts run more than 2.5 times faster than in previous versions now! No changes needed, just update!
• You can convert scripts (scriptPacks) into plugins now!
• Added support for minecraft version 26.1
• Reviewed and fixed numerous bugs across the entire codebase.
• Added a debug mode boolean to the config for easier troubleshooting.
• Fixed a bug where reloading with the reload command would not update the debug mode boolean until a full restart.
• Fixed an issue where deleting folders inside the script folder was not possible due to the file watcher locking them.
• Removed all deprecated code and cleaned up a large portion of the codebase.

Dialog API

• Created a new DialogApi for managing in-game graphical dialogs.

Task API

• Tasks are now shared across all scripts, meaning they can be cancelled from external scripts using setShared and getShared.
• Added task.latch() which returns an object with the following thread-safe methods: .destroy(), .connect(function), .wait(), .invoke(), .fire(), and .invoked.
• Added task.threadType() which returns a string indicating the thread type (main, async, or sync).
• Enhanced thread safety in DelayTask by properly handling thread interruptions.

FileManager API

• Added FileManager.getPath(File), which returns the relative path of a file based on the script's folder.
• Added support for ZIP files: any .zip file containing an info.json will automatically be extracted into a folder named after the zip file.
• Fixed a bug where the file watcher could receive null paths, causing errors.
• Improved watcher robustness by handling OVERFLOW events and adding a null check for the watch service when clearing listeners. This fixed many errors with the file listener, its more reliable now

ProtocolLib Integration

• Added the following new ProtocolLib methods:
  • broadcastServerPacket(packet, source, broadcastRange) broadcasts a packet to nearby players.
  • sendServerPacket(player, packet) sends a packet directly to a specific player.
  • createPacket(packetTypePath) creates a packet by type path.

PlaceholderAPI

• Fixed parseString not working correctly when passing an offline player as the target.

Inventory API

• Added the following new methods:
  • getSlot(slot) retrieves the item in a given slot.
  • setItemLore(slot, lore) sets the lore of an item in a slot.
  • setItemName(slot, name) sets the display name of an item in a slot.
• Fixed colors not being applied correctly in item lore.
• Added backwards compatibility for Inventory.setTitle via ProtocolLib.

Service Objects & Internal Refactoring

• Refactored Folia support initialisation for improved performance, including a centralised init() method and pre-cached scheduler.
• Refactored setShared() & getShared() , replacing complex lock logic with a simpler and safer wait()/notifyAll() approach.
• Optimised script preprocessing to read from CODE_CACHE first, avoiding unnecessary disk reads.
• Switched import ID generation in importJavaToJsGC from random strings to an AtomicLong counter (__import_0, __import_1, ...) for better performance.
• Added player permission verification (openjs.use) at the start of onCommand to prevent unauthorised command execution.
• Added Array.from() support.
• Created custom mappings to support Minecraft 1.13 through the current version.
• Fixed importClass() it now correctly translates Java classes into Javascript objects
• Fixed Java.type() it can now correctly read and translate external plugin classes too! This is huge, trust me :)

Thank you, guys, for downloading this plugin. I’ve poured my heart and a lot of passion into this project 💚
