Plexus Mod Loader adds Fabric API biome and content registries modules on MinecraftForge 26.2 and 26.3, unloaded-mod notices, separate bundled mod counts, and NeoForge client fixes.

✨ What's New

• Run fabric-biome-api-v1 and fabric-content-registries-v0 on Forge hooks next to MinecraftForge 26.2 and 26.3, allowing Balm and Puzzles Lib to load (Architectury remains excluded).
• Support Continuity on NeoForge clients by bridging SpriteSourceList.list(ResourceManager) to list(ResourceManager, Set) (PLEXUS-COMPAT-226).
• Add unloaded-mod warnings (PLEXUS-COMPAT-209, PLEXUS-COMPAT-217, PLEXUS-COMPAT-224) as an amber line above the progress bar, a title-screen count and notice, and a logs/latest.log line.

v1.8.0

Minecraft: 26.1, 26.1.1, 26.1.2, 26.2, 26.3

Plexus Mod Loader adds client-side Fabric API support next to NeoForge 26.2 and 26.3, runs Fabric API data generation, and fixes Fabric mod compatibility next to NeoForge and MinecraftForge.

✨ What's New

• Run fabric-rendering-v1, fabric-renderer-api-v1, fabric-renderer-indigo, and fabric-model-loading-api-v1 builds from Forgified Fabric API on NeoForge 26.2.0.93 and 26.3.0.98 (ADR-0031).
• Run fabric-screen-api-v1, fabric-sound-api-v1, and fabric-rendering-fluids-v1 on NeoForge via ScreenEvent, SoundInstance.getStream, and BlockState.shouldDisplayFluidOverlay.
• Support all Fabric API modules on NeoForge 26.2 and 26.3 clients, loading 60 tested foreign mods (50 in 1.7.1); only Continuity (both) and FancyMenu's Fabric build (26.3) stay out.
• Support Fabric API data generation (-Dfabric-api.datagen) on Plexus Mod Loader, writing tags, loot tables, translations, and recipes as under Fabric Loader.

🔧 Improvements & Fixes

• Fix fabric-data-attachment-api-v1 on NeoForge clients by moving slice boundaries to the startWaitingForNewLevel overload in ClientPacketListener.handleRespawn (PLEXUS-COMPAT-226).
• Fix fabric-data-generation-api-v1 on MinecraftForge 26.3 by using Forge's TagBuilder removal list and running loot vanilla-namespace filters where Forge iterates blocks and entity types.

✨ What's New

• Run fabric-content-registries-v0 next to NeoForge 26.2.0.93 and 26.3.0.98 for compostables, fuels, 26.2 stripping and tilling, oxidation and waxing (26.3 data maps), and fluid types.
• Support fabric-data-generation-api-v1 next to NeoForge 26.2.0.93 (loading mods like Fusion and writing tag removals without "Implemented via mixin") and 26.3.0.98 (PLEXUS-COMPAT-224).

• Fix MinecraftForge server stops on Fabric extended menus ("Codec for ... is not registered!") by firing RegistryEntryAddedCallback where Forge registries skip MappedRegistry.register.
• Fix Fabric tag removals (fabric:remove in data packs and Fabric data-generator removals) with MinecraftForge and NeoForge by returning both lists from TagFile.remove().
• Fix client loading of fabric-lifecycle-events-v1 and fabric-content-registries-v0 next to NeoForge 26.3.0.98 by running tags-loaded when creative search trees rebuild.

v1.6.0

Minecraft: 26.1, 26.1.1, 26.1.2, 26.2, 26.3

Plexus Mod Loader makes Minecraft 26.3 the default version, runs its own builds of Fabric API modules on NeoForge 26.2 and NeoForge 26.3 hooks, and fixes Fabric compatibility next to NeoForge and MinecraftForge.

✨ What's New

• Run projects without plexusMinecraft, runClient/runServer, and verification tasks on Minecraft 26.3 by default; support 26.1, 26.1.1, 26.1.2, and 26.2 (plexusMinecraft=26.2).
• Support dynamic registries, mob attributes, block entity blocks, and data serializers on NeoForge 26.2.0.93 and 26.3.0.98 (fabric-registry-sync-v0, fabric-object-builder-api-v1 builds).

🔧 Improvements & Fixes

• Fix Fabric mod initialization order next to NeoForge on dedicated and game test servers so Mob.createMobAttributes() in onInitialize and Fabric registry builders no longer fail.
• Fix lost FabricDefaultAttributeRegistry.MODIFY modifications next to NeoForge by allowing host modules to replace loaded modules that behave differently (ADR-0031, always).
• Fix Missing registry: forge:biome_modifier server stops next to MinecraftForge when Fabric mods use DynamicRegistries by keeping Forge data pack registries in the world loader list.
• Fix crashes next to NeoForge: omit a mod with PLEXUS-COMPAT-224 instead of moving a Fabric @Inject with parameters (fabric-menu-api-v1 on ServerPlayer.openMenu) to other parameters.

v1.5.0

Minecraft: 26.1, 26.1.1, 26.1.2, 26.2, 26.3

Plexus Mod Loader renames every remaining Poly file, identifier, and developer tool to Plexus while keeping compatibility with 1.4.x launcher profiles, mods, and worlds.

🔧 Improvements & Fixes

• Rename launcher profiles to plexusmodloader-<minecraft> (plexusmodloader-<plexus>-<minecraft>), moving 1.4.x profiles with settings on reinstall and removing both on uninstall.
• Switch IDs to plexus:* (accepting poly:game_brand), properties to plexus.* (copying poly.*), and paths to .plexus/, config/plexus/, and <world>/plexus/ (reading 1.4.x files).
• Remap classes compiled against PolySystem (either package) at class load to the renamed PlexusSystem API, and use the assets/plexus resource namespace.
• Update the SDK, Gradle plugin, and template to Plexus names (including plexusResources, newPlexusMod, initPlexusMod, and -PplexusMinecraft), keeping former names working.
• Keep 1.4.x mods, projects, and worlds working (poly.mod.json, dev.polymodloader.*, dev.polymodloader.mod, existing dev.polymodloader, poly dependency, poly:code_structure_piece).

This release rebrands in-game UI and window titles to Plexus Mod Loader and adds plexus mod metadata, dependency, and game brand identifiers while keeping poly backward compatibility.

✨ What's New

v1.4.0

Minecraft: 26.1, 26.1.1, 26.1.2, 26.2, 26.3

This Poly Mod Loader release for Minecraft 26.1, 26.1.1, 26.1.2, 26.2, and 26.3 adds a shared client early loading window, supports more Fabric API modules on NeoForge, and fixes Forge and NeoForge mod compatibility.

✨ What's New

• Add a shared client early loading window like the game's loading screen, replacing FML's window on MinecraftForge and NeoForge (not on macOS yet; disable via -Dpoly.earlyWindow=off).
• Support fabric-resource-conditions-api-v1 on NeoForge 26.2, and fabric-crash-report-info-v1 on NeoForge 26.2 and 26.3 without POLY-COMPAT-225.
• Add fabric-block-api-v1 and fabric-item-api-v1 host modules on NeoForge 26.2.0.93 replacing POLY-COMPAT-224; 47 mods in the popular Fabric mods set now load on 26.2 (was 40).

🔧 Improvements & Fixes

• Fix NeoForge stopping with POLY-COMPAT-208 (NoSuchMethodError: FabricLoaderImpl.setup()) with Forgified Fabric API by excluding nested forgified-fabric-loader FML plugins.
• Claim Fabric API fluid and item hooks under Forge only where they run.
• Inspect host-patched jars before vanilla jars in ModLinkVerifier, excluding incompatible mods like fabric-biome-api-v1 on Forge with POLY-COMPAT-112 instead of failing later.
