v2.1.4

Minecraft: 1.20.1, 1.20.4, 1.21.1, 1.21.11, 26.1, 26.1.1, 26.1.2, 26.2, 26.3

Plexus Mod Loader 2.1.4 keeps obfuscated stack map frames unchanged in remapped pre-26.1 game jars so the Minecraft 1.20.1 Quilt game test server runs, fixes Forge 47 and NeoForge 20.4 startup, mod discovery, and enum extension issues so corpusQuiltForge passes on 1.20.1, and verifies installed launcher profiles on Forge 1.20.1, 1.20.4, 1.21.1, and 1.21.11 and NeoForge 1.20.4, 1.21.1, and 1.21.11 as well as Fabric client windows alongside NeoForge 21.1.265.

🔧 Improvements & Fixes

• Keep the obfuscated jar's stack map frames as they are in remapped pre-26.1 game jars (remapper revision 5, regenerating remapped jars on first launch) and make this and parameters live in frames only inside methods changed by a Plexus transform rule (moving ParameterFrames into ClassTransformExecutor in the transform engine), fixing Mixin 0.8.7 local capture broken by revision 4's widened frames in Cardinal Components API 5.2.3's block-module implicit @ModifyVariable in BlockInput.place (1.20.1) and Fabric API's lifecycle LocalCapture in LevelChunk.setBlockEntity while keeping QSL passing on 1.20.1, 1.20.4 (Polymer), and 1.21.1.
• Include corpusQuilt on Minecraft 1.20.1 in compatibilityCorpus now that the 1.20.1 Quilt game test server runs past Cardinal Components API, loading 184 mods with 877 not loaded (leaving Graphene 1.5.0 out of that run because its server tick handler loads an unmapped client class) alongside 186 loaded / 821 not loaded on the 1.20.1 Quilt dedicated server.
• Fix startup crashes (PLEXUS-COMPAT-208) on Forge 1.20.1 (Forge 47) in installed launcher profiles, where securejarhandler 2.1.10 on the JVM class path needs java.lang.invoke opened and a union: URL handler, by passing the Java agent's JDK module access to the Forge game host, opening java.lang.invoke, and installing the union: URL handler shared with NeoForge, passing launcherProfileForgeTest on 1.20.1, 1.20.4, 1.21.1, and 1.21.11 and launcherProfileNeoForgeTest on 1.20.4, 1.21.1, and 1.21.11 (installed Forge and NeoForge launcher profiles on 1.20.1, 1.20.4, and 1.21.1 were unverified in 2.1.3).
• Fix NeoForge 20.4 (FML 2) stopping with "Missing language javafml version" by leaving out javafml mods whose mods.toml has an empty or missing loaderVersion before FML starts (PLEXUS-COMPAT-217), allowing multi-loader jars such as YACL 3.6.6 to run through the Fabric bridge so Zoomify finds YACL.
• Fix Forge 47 (Minecraft 1.20.1) stopping with "has mods that were not found" by leaving javafml jars whose mods.toml declares a mod with no matching @Mod class (data packs packaged as mods and multi-loader Quilt or Fabric jars carrying another loader's mods.toml, such as a Sinytra Connector placeholder) out of Forge discovery (PLEXUS-COMPAT-209) so multi-loader jars fall back to the Quilt or Fabric bridge, while leaving Forge 49 and later unaffected.
• Fix Forge's RuntimeEnumExtender failing with "Enum has create method but we could not find $VALUES" when a Fabric or Quilt access widener widens an enum's $VALUES field (such as EnchantmentCategory on Forge 1.20.1) by showing the plugin $VALUES with its compiled flags (private static final synthetic) and restoring the widened access afterwards.
• Pass corpusQuiltForge (Quilt mods next to Forge) on Minecraft 1.20.1 with 98 loaded mods, leaving Metal Pipe 1.0.5 (illegal access to Forge's private EnchantmentCategory constructor) and Cardinal Components API 5.2.3 (local variable mismatch in Forge's patched FallingBlockEntity.tick) out of that run.
• Verify Fabric mods next to NeoForge 21.1.265 (Minecraft 1.21.1) in a game client window, passing corpusFabricNeoForgeClient after reaching the world, running 200 ticks, and leaving.
• Verify the 2026-11-08 release on Java 25 with check, build-logic check, headless runs on all 9 supported versions (serverBootSmokeTest, worldCreateSaveTest, gameTests *:*, and compatibilityMatrix, 172-213 s per version), compatibilityCorpus on all 9 versions (last-stage loaded / not loaded: 1.20.1 Quilt server 186 / 821, 1.20.4 111 / 153, 1.21.1 109 / 123, 1.21.11 123 / 96, and 26.1 Quilt server 116 / 72), and all 20 window tasks run one at a time 20 s apart (clientWorldReloadTest on 1.20.1, 1.20.4, 1.21.1, and 1.21.11, with 26.x not rerun as no 26.x game-layer code changed since 2.1.3; corpusForgeClient and launcherProfileForgeTest on 1.20.1, 1.20.4, 1.21.1, and 1.21.11; corpusNeoForgeClient and launcherProfileNeoForgeTest on 1.20.4, 1.21.1, and 1.21.11; corpusFabricNeoForgeClient on 1.21.1; and launcherProfileTest on 26.3).
