# Changelog Notable changes to Data Attributes are documented here, newest release first. The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/). ## [Unreleased] ## [3.0.0] - 2026-10-07 Minecraft 1.21.1 rewrite for Fabric and NeoForge. ### Added - NeoForge support alongside Fabric for Minecraft 1.21.1. - Server-authoritative Fzzy Config JSON5 configuration for both loaders. - Live application of accepted in-game configuration changes. Loaded living entities adopt supplier-owned base changes on their next tick. - An informational Datapack Baseline Preview for attribute overrides, functions, and entity base values, synchronized from the server and never saved back to configuration or datapacks. - Configuration suggestions for registered entity types and Data Attributes' implicit entity groups. - Persistent supplier-base tracking so configured base values can update without overwriting deliberate runtime changes, including `/attribute ... base set`. - Reattachment to supplier ownership when a live base is set back to its current configured value. - Bounded GZIP synchronization of runtime configuration snapshots. - Kotlin serialization compiler support for datapack and runtime snapshot serialization. ### Changed - Attribute Definition Overrides now control bounds, stacking behavior, diminishing smoothness, and display formatting separately from entity base values. - Entity Base Attributes are the configuration and datapack layer responsible for assigning entity supplier base values. - Entity configuration resolves from vanilla defaults through matching implicit groups to explicit entity entries. Server configuration overrides the datapack baseline. - Entity base values remain raw; attribute bounds constrain the calculated result rather than rewriting stored configuration values. - Entity entries apply as deltas, avoiding unnecessary supplier rebuilds and preserving inherited values not explicitly overridden. - Configuration fields are organized into Bounds, Stacking, and Display groups. Explicit Override Minimum/Maximum switches replace user-facing `NaN` inheritance values. - Attribute Function descriptions clarify that the outer key is the parent/source attribute and the nested key is the child/derived attribute. - Identifiers belonging to absent optional mods can remain configured. - Datapack reloads rebuild configuration once at reload completion and respect normal resource-pack priority. - Native Fabric/NeoForge custom-payload networking replaces the OWO network channel, and a loader-neutral event implementation replaces OWO event streams. - Loader-specific Fzzy Config integrations use `0.7.7+1.21` on Fabric and `0.7.7+1.21+neoforge` on NeoForge, with shared runtime code consuming loader-neutral snapshots. - Disabled server override entries suppress matching datapack overrides. - Project metadata and documentation now reference the Bare Minimum Studios repository and the Bare Minimum License (BML) v1.0. ### Removed - OWO Lib/OOLib, OWO Sentinel, and Endec dependencies and their associated repository declarations. - The old `/reload` command-tail hook. - Vanilla sword/tool hooks that incorrectly treated durability damage as attack damage. - Duplicate mob equipment-comparison injections. - Unused OWO interface code and legacy helpers. ### Fixed - Configuration map additions failing with `Identifier invalid or not allowed`, using valid defaults, identifier validation, and live registry suggestions. - NeoForge compilation failures caused by Fabric-mapped Fzzy Config classes entering shared source. - Runtime modifiers being lost during live configuration rebuilds. - Explicit entity entries resetting unrelated inherited values to vanilla defaults. - Attribute dirty/update/synchronization behavior affecting health, absorption, and other stateful attributes after live rebuilds. - Resource-stack rebuilding mutating maps during iteration. - Self-referencing functions and non-finite function coefficients or entity base values are safely ignored. - Implicit entity-group entries being discarded during registered-ID filtering. - Standalone and supplier attribute modifier additions, modifier-removal bookkeeping, and dependent-function invalidation after base or transient changes. - Incorrect Holder-versus-Attribute casts in diminishing stacking and formatted-value lookup. - Implicit entity-category definitions crashing when no vanilla supplier exists. - Stale attribute override state remaining after an override is removed.

## Additions 🍎 - Data Attributes is now on 1.21.1 for fabric & neoforge! - Add button for Entity Types (will downstream this to 1.20.1 momentarily). ## Changes 🌽 - Resolved source identifier on jars. - `EventSources` are used in replacement of fabric api events to be more compatible with multi-loader. Event classes have been renamed. - `AttributeEvents` - `AttributeModifiedEvents`

## Additions 🍎 - DataAttributes is now on 1.21.1 for fabric & neoforge! - Add button for Entity Types (will downstream this to 1.20.1 momentarily). - I cannot guarantee its stability (specifically in the areas of attribute modification). If there are no issues, I'll stabilize it later. ## Changes 🌽 - `EventSources` are used in replacement of fabric api events to be more compatible with multi-loader. Event classes have been renamed. - `AttributeEvents` - `AttributeModifiedEvents` This update affected a sector of mixins which I have redone, but I will keep it in beta until its stability is ensured along with PlayerEX.

## Fixes 🍋 - Remove null text in UI in favor of empty string to fix compatibility with other mods

## Additions 🍎 - Added saved state for collapsed entries (session based, saved until game relaunch) ## Changes 🍐 - Applied a different method to updating UI components. - Most entries sync, but there is still some work to do, so it will stay as beta until the rest of the issues are figured out.

## Fixes 🍋 - Fixed attribute functions not being able to be edited (and that were default).

## Changes 🌽 - Resolved an exception that happened with the `DefaultAttributeRegistry`. ## Fixes 🍋 - Resolved percentage formatting, should be more accurate now
