Bug Fixes

• avoid ghost items after sword block restore (822fb1f), closes #749
• don't prevent moving shield to chests in disable offhand module (b299df2)

Features

• Full support for Spigot 1.20.6, including new potion and enchantment names. This fixes potion, golden apples, fishing knockback, and damage modules on newest version
• You can now disable messages by setting relevant string in config.yml to empty ""

Changes

• Minimum Java version required is now Java 17, but plugin still supports Spigot 1.9 through 1.20.6
• Removed player-collisions module. This module relied on NMS and kept breaking with almost every new version of the game, or when running with badly-coded scoreboard plugins. You can use the enable-player-collisions option in paper.yml instead.
• Removed SpartanAPI dependency. Library repository for API disappeared and this was breaking builds.

Bug Fixes

• Account for fake overdamage from environmental sources. This was causing issues with players getting large amounts of damage too quickly if they received non-combat damage and then were hit by another player again, bypassing damage immunity.
• Fix NullPointerException when sending custom sounds (e.g. using resource pack with sound modules). Thanks @Waischbrot
• Fix no getPlayer method for BlockCanBuildEvent when using sword-blocking module in Spigot 1.12.2 or lower
• Fix gapple module effects overriding pre-existing but longer effects of same strength (e.g. regen would be reset down even if player already had longer regen effect)
• Fix splash potions being thrown in the sky not being affected by old-potion-effects module

Bug Fixes

• Fix error using /ocm mode when current world not in config
• Fix mode.own permission not working

New Features

• Added placeholders for enderpearl, gapple, and napple cooldowns. See wiki for more details.

Features

• Added per-user combat mode "modesets" supporting all modules, not just attack speed
• You can now configure as many modesets as you like, and specify which modules should be enabled when a player is in that modeset
• You can specify which modesets are allowed in which worlds
• Modesets are persistent across server restarts
• Players can switch between allowed modesets with /ocm mode for their current world
• This allows players to choose what combat mode to be in, as long as they have the permission. The mode of the attacker takes precedence for any given damage calculation, to allow for a fair fight.
• PlaceholderAPI support has been updated to display the player's current modeset for the player they are in with %ocm_modeset%

Important Changes

• Fixed last damage calculations not taking into account non-entity damage. Improves compatibility with other plugins and fixes problems with damage immunity.
• Moved worlds section from individual module configs to new modesets section
• Removed toggle, enable, and disable commands. These have been replaced by the mode command.

Build changes

• Fixed sword blocking not triggering when right-clicking air

• Fixed damage calculation not being applied when running Spigot < 1.16 and having attack cooldown enabled
• Fixed errors with get absorption method when running Spigot < 1.15
• Fixed problems with eating golden apples being reset when damage taken

This release is the culmination of a lot of work in making sure the damage calculations in the plugin are as accurate as possible. Extensive automated testing was conducted in order to make sure the weapon behaviour is accurate, and a lot of problems were found. They have now been fixed, and you will find the damage reflects the configuration as closely as possible. Additionally, compatibility with other plugins modifying damage was improved significantly.

Compiled with & updated to 1.9.2

The Update Checker would stop the plugin from working in the case it could connect to BukkitDev but no files were found. This release fixes it.
