If you used item economy or exp levels as economy, you need to enable it again after updating.

+ Added: [Suggestion] Use player experience instead of just levels for eco
+ Added: Strict comparison for item eco
Code (YAML):
# Player experience
exp:
enabled_15: false
# Item currency is used when all other economy options are disabled or unavailable.
# The currency item can be edited in the GUI language file at the "currency" item.
items:
# If enabled, only items that have the same name, lore etc. will belong to the currency.
# Not just items of the same type or items with the same model-data.
strict: false
[#2212]

- Fixed: [#2211] Menu not opening because of missing butcher item

+ Changed: Moved force-butcher to entities.yml
Allows you to set it per entity type

Example:
Code (Text):
pig:
name: Pig
cost: 5000.0
skull: eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNTI3ZWM0NTllYzhiYTM1YWY5YmI0YzdlMDQ5YzdjZThkMjM0NTAyNWJjNDc0NDY2NDdhNTFiODE0YjMwOWRiOCJ9fX0=
# '/Spawners get' will give a pig spawner. You can just remove this option and place it somewhere else to change the default entity.
default: true
# Should spawners of this entity type to have butcher mode enabled?
# This does save performance, since no living entities are spawned. This acts like a virtual spawner
# that doesn't spawn any entities, but still harvests their loot.
# If you disable this option again, then butcher mode will be set to the state each induvidual spawner had before
# it was enabled.
force-butcher:
always: false
- Fixed: [#2180] Param names

- Fixed: Error on saving new spawner

+ Added: [Suggestion] You can now manually pause a spawner in its menu
Also this adds some more information on why spawners are paused.

- Fixed: DB issue

+ Changed: Save spawner immediately if upgrade menu closed and changes were made, async ofc.

+ Added: Option to disable stacking for vanilla spawners as well:
Code (Text):
# Should spawned entities be stacked?
stacking:
enabled_2: true
# Should entites, spawned by vanilla spawners, be stacked too?
# NOTE: This option requires server reload / restart.
vanilla: false
- Fixed: [#2182] Entity stacking not completely disabled for vanilla spawners
- Fixed: [#2178] Reducing stack amount did not call entity death event for 3rd party plugins

+ Changed: [#2154] Spread no-condition spawns more evenly on more tasks
Entity stacking is coming soon as well.

- Fixed: [#2151] Not being able to disable period_amount upgrade by setting period time to 0
This should also fix spawning issues with servers, having that set to 0.

+ Added: [Suggestion] Option to cancel vanilla spawners spawning entities
Code (YAML):
# Allow vanilla spawners to spawn entities?
spawn: true
