Built-in Addons & Guide Parity

Slimefun Legacy 4.1.50 continues the effort to preserve classic Slimefun and addon behavior while making older content feel native on current Minecraft versions. Built-in ExtraGear and ExtraTools

ExtraGear and ExtraTools are now maintained directly inside Slimefun Legacy as optional internal addons. Both are enabled by default through configSFLAddons.yml, while duplicate protection prevents the built-in copy from registering when a standalone plugin with the same addon name is installed. Dedicated Slimefun Guide pages

The bundled addons now match the original standalone guide experience again:

ExtraGear has its own top-level ExtraGear page containing its swords and armor.
Extra Tools has its own top-level Extra Tools page containing the Hammer and ExtraTools machines.
ExtraGear content is no longer mixed into Slimefun's core Weapons or Armor pages.

The original ExtraGear extragear:items group and ExtraTools extratools:extra_tools group identities are preserved. Compatibility preservation

The built-in imports preserve the historical contracts players and worlds depend on:

legacy Slimefun item IDs
research namespaces and research IDs
recipes
enchantments
machine behavior and inventories
saved-world and stored-item compatibility

Regression checks now protect both the addon import contracts and their dedicated guide-page placement. ExtraTools correction

The ExtraTools Cobblestone Generator tooltip now reflects its real machine behavior: a 512 J power buffer and approximately 32 J/s average consumption. This is a display correction only; its production rate and energy mechanics are unchanged. Addon bundle

The refreshed SFL_AddonsNDependencies.zip is rebuilt from current maintained addon releases and dependencies. Standalone ExtraTools and ExtraGear JARs are intentionally excluded because those addons are now available directly inside Slimefun Legacy. Server compatibility

The changes in this release were validated through the Slimefun Legacy CI matrix, including:

Paper 26.2
Purpur 26.2
Folia 26.2
Leaf 26.2
Paper/Purpur 1.21.11 compatibility
Paper 26.3 pre-release preflight
Public API compatibility
Slimefun addon compatibility probes

Upgrading

If your server currently uses standalone ExtraGear or ExtraTools, remove those standalone JARs when moving to the built-in versions. The internal modules are enabled by default. Servers that deliberately want to keep a standalone copy can do so; Slimefun Legacy detects it and skips registration of the corresponding built-in module.

Please Update Any Addons even ones with same version, ive made alot of little tweeks https://github.com/wickidcow/Slimefun-Legacy/releases !
