🛠️ Version 1.0.5

Bug Fixes

Crystal Placement Broken on Stacked Obsidian (Default Mode)

• Fixed a bug in Default Mode where crystals could not be placed when targeting obsidian that had another obsidian or bedrock block directly on top of it.
• Root cause: The mod's placement check called isSpaceFree on the block directly above the raycasted position. When looking at the lower obsidian in a stack, that position was the upper obsidian itself — not air — so the check always failed and no crystal was sent.
• Fix: The mod now walks up any stack of valid base blocks (obsidian/bedrock) to find the topmost one before checking space and placing, matching vanilla crystal placement behavior regardless of how many blocks are stacked.

Improvements

Mode Toggle Feedback Moved to Action Bar

• /g1axoptimizer default, tweak, and off no longer dump lines of text into your chat.
• Mode changes now show a single clean confirmation above your hotbar (the action bar), which fades automatically — no chat clutter mid-fight.
  • ✔ Default Mode — Full optimizer enabled
  • ✔ Tweak Mode — AC-safe cooldown bypass enabled
  • ✗ Optimizer Disabled — Vanilla crystal behavior
• /g1axoptimizer with no arguments still prints the current mode and usage to chat since that's a deliberate status check.

🔮 G1ax Crystal Optimizer Release Notes

🚀 Version 1.0.4-mc26.2 (Minecraft 26.2 Support)

This release adapts the G1ax Crystal Optimizer mod to support Minecraft 26.1.2 & 26.2 running on the latest Fabric loader.

New Features & Optimizations

• Java 25/26 Platform Support: Compiled with compatibility for Java 25 compiler specs and optimized to execute efficiently on modern JDKs.
• Unobfuscated Mojang Mappings: Fully transitioned class references and mixin targets to match Mojang's official unobfuscated mapping environments.

Re-architected Components (Minecraft 26.2 Compatibility)

• Record Packet Adapter: Adapted the outgoing packet interceptor inside the ClientConnection mixin to query the new flat record structure of ServerboundInteractPacket. Evaluates the presence of hand() == null to correctly optimize attacks without using the deprecated/removed inner Handler interface or dispatch() method visitor patterns.
• Refactored GUI & Chat Accessor: Migrated in-game command messages to print system feedback using the new mc.gui.hud.getChat().addClientSystemMessage(Component) path, aligning with the updated HUD class layout in Minecraft 26.2.
• Fabric API Networking Update: Upgraded packet payload registrations in Main.java to use the modernized Fabric API methods (clientboundPlay(), serverboundPlay(), and clientboundConfiguration()), resolving packet-registry mismatches and preventing client-side launch crashes.
• Tooling Compatibility: Upgraded Lombok annotation processor version to 1.18.46 in the Gradle build pipeline, resolving compilation daemon ExceptionInInitializerError crashes when building under Java 26.

🔮 G1ax Crystal Optimizer Release Notes

🚀 Version 1.0.4

New Features

Performance Enhancement

• Integrated PerformanceGuard: A nanosecond-precision, ping-adaptive rate limiter with independent budgets for placing and breaking to maximize PvP performance.
• Added OptOutCache: Multi-server session-persistent opt-out memory that retains server-requested disable states across logins (up to 10 servers).
• Handshake Protocol Integration:
  • VersionPacket (C2S): Announces current project version to server.
  • ServerOptOutPacket (S2C): Receives server instructions to disable the optimizer, displaying a clean hoverable notification in game.
  • OptOutAckPacket (C2S): Acknowledges server opt-out commands.

Modrinth Auto Update Checker

• Added UpdateChecker.java — a lightweight background update checker powered by the public Modrinth API (no API key required).
• On mod load, a daemon thread silently fetches the latest published version from api.modrinth.com.
• The first tick the player enters a world, if a newer version is available, a single beautifully formatted notification is displayed in chat with the download link and custom dev contact.
• Shows once per session only — no spam.
• If already on the latest version, completely silent.

Bug Fixes

Command Output Colors Not Rendering

• Fixed all § color codes in chat messages being silently ignored.
• Root cause: MutableText.formatted() is non-mutating — the returned styled text was discarded, causing every color, bold, and italic code to fall back to plain white.
• All command output (/g1axoptimizer default, tweak, off, status) now renders with correct gold, green, red, yellow, and gray formatting.

Classloading Mismatch / Mixin Startup Crash (Minecraft 1.21)

• Resolved startup crash with ClassMetadataNotFoundException: net.minecraft.class_1269$class_9859 when running on Minecraft 1.21.
• Root cause: ActionResult was refactored from an enum to a sealed interface in 1.21.2+. Compiling against 1.21.11 caused references to ActionResult.PASS to seek non-existent inner records.
• Solution: Introduced ActionResultResolver.java using reflection to dynamically retrieve SUCCESS, CONSUME, and PASS constants across all Minecraft 1.21–1.21.11 builds, resolving any compile-time bytecode dependency on the inner classes.

Incorrect Compatibility Warnings on Production/Obfuscated Clients

• Fixed startup log output displaying Minecraft: unknown and reporting INCOMPATIBILITY: Mixin targets not found: MinecraftClient, EndCrystalItem, ClientConnection.
• Root cause: CompatibilityChecker looked up named classes (MinecraftClient, etc.) which are obfuscated to intermediary names (class_310, etc.) in the production environment. Also, SharedConstants reflection failed due to obfuscated method names.
• Solution: Updated CompatibilityChecker to query both named and intermediary names for class presence, and integrated Fabric Loader's mod container version lookup for robust, obfuscation-safe Minecraft version detection.

NoSuchMethodError Registry Crash on Older Fabric API Versions

• Resolved startup crash throwing NoSuchMethodError: 'net.fabricmc.fabric.api.networking.v1.PayloadTypeRegistry.playC2S()' when running on older Fabric API versions.
• Root cause: The mod registered packets directly via the PayloadTypeRegistry class APIs which did not exist or had different signatures on older Fabric API versions.
• Solution: Migrated all packet registrations to use reflection and dynamic method lookup (handling missing classes and method mismatches gracefully), allowing the mod to start up without crashes on all Fabric API versions.

NoClassDefFoundError HoverEvent$ShowText Crash on Minecraft 1.21/1.21.1

• Resolved startup crash throwing java.lang.NoClassDefFoundError: net/minecraft/class_2568$class_10613 (HoverEvent$ShowText) when running on Minecraft 1.21/1.21.1.
• Root cause: Minecraft 1.21.2+ introduced HoverEvent.ShowText (obfuscated as class_2568$class_10613). Compiling against 1.21.11 introduced a direct bytecode reference to this class, which does not exist in Minecraft 1.21/1.21.1 client runtime environments.
• Solution: Created HoverEventResolver.java using dynamic reflection to detect class availability. It dynamically instantiates HoverEvent.ShowText on 1.21.2+ environments and falls back to passing Text directly on 1.21/1.21.1 environments, removing all static compile-time classloading references.

🔮 G1ax Crystal Optimizer Release Notes

🚀 Version 1.0.3

New Features & Enhancements

[Issue 3] Clean Formatted Live Logging Engine

• Replaced the messy standard log output with a beautifully formatted live logging engine in Logger.java.
• Log lines are structured cleanly (e.g. [HH:mm:ss] [G1ax/LEVEL] Message) and written to a dedicated log file at .minecraft/logs/g1axoptimizer-latest.log.
• Implemented automatic log rotation that preserves the last 3 log files (g1axoptimizer-1.log, g1axoptimizer-2.log, g1axoptimizer-3.log) to keep log directory clean.

[Issue 4] Pre-Flight Compatibility Diagnostics

• Added an automatic check engine in CompatibilityChecker.java that runs on startup.
• Automatically validates Minecraft version, Fabric API, Payload Registry support, Mixin targets, and Java 21+ configuration.
• Generates step-by-step resolution guides in the dedicated log file and triggers an alert in-game if any compatibility issues are found.

[Issue 5] AC-Safe Tweak Mode

• Added Tweak Mode configurable via /g1axoptimizer tweak.
• Bypasses the 4-tick client-side placement cooldown (itemUseCooldown = 0) while keeping the rest of the placement validation and packet logic completely vanilla.
• Safe to use on competitive servers with strict anticheats.

[Issue 6] Cross-Version Compatibility Fixes

• Replaced static method and field lookups (such as MinecraftVersion.CURRENT and SharedConstants.getGameVersion().getName()) with a robust reflection resolver.
• Automatically checks for getId(), getName(), and getVersionId() to run stably across various Minecraft versions without compilation or launch failures.
