React - Smart Server Performance 2.1.0-26.1.2-26.3

• Updated release packaging with compression and removal of unused archive and debug metadata.

• Added Minecraft 26.3 support.
• Moved native monitoring and optimization hooks to the shared VolmLib backend.
• Improved reporting when a required native capability is unavailable.

• Expanded mob stacking to compatible farm animals, creepers, and endermen while preserving supported species traits and state.
• Fixed stack splits, health preservation, labels, and replacement spawns.
• Creeper explosions consume one stack member and restore the remainder with a fresh fuse.
• Turning off mob stacking while React remains enabled now gradually restores individual mobs and retries blocked replacement spawns.
• Fixed Folia plugin chunk-ticket sampling and added explicit reporting when the metric is unavailable.
• Configuration and language edits now apply automatically (Hot Reloadable).
• Updated the translations with missing variables and messages across all translations and added English as a fallback.
• Removed duplicate or incorrectly translated hot reload messages.
• Fixed startup worker initialization and Windows environment-report formatting /react environment.
• Prevented synthetic protection checks from resetting AFK/activity tracking, splitting mob stacks, or interrupting entity cleanup.

• Prevented entity purging from removing Ender Dragons, including when custom filters allow them.
• Fixed optional world arguments accepting ordinary world names.
• Stopped displaying "unknown command" after an already-handled command failure.
• Integrated mob-stack counts with Gloss entity overlays, retaining native stack labels when overlays are unavailable.
• Preserved player-assigned mob names when updating or copying stack state.
• Updated jar shrinking to preserve public APIs and integrations, and streamlined tests.

• Redesigned the web dashboard with revised navigation, denser data views, and a contextual server inspector.
• Added resizable side panels and responsive layouts for smaller screens.
• Added a light theme with a saved theme preference.
• Reworked actions, configuration, logs, world overrides, and fleet management screens.
• Improved charts, heatmaps, and metric exploration.
• Improved loading, offline, and unavailable-data states.
• Added clearer server-pairing instructions and expanded language support.
• Improved removal-dialog keyboard navigation, mobile controls, and favicon handling.

• Added Server / Per User Language Selector /react language
• Added Shared Debug Dump Command /react debugdump
• Updated Language files to pull language files from GitHubs Repo
• Fixed PluginApiTest on Windows Machines

• Added the ability to remove sites from https://react.volmitsoftware.com
• Fixed the favicon
• Fixed language translations across the site

• Added /volmit plugins languages command to easily change all supported Volmit plugins languages at once
• Added /volmit plugins debug all command to easily do a debug dump of all supported Volmit plugins at once, use the upload=false key to turnoff mclo.gs upload
• Added shared mclo.gs uploading with plugin/version metadata and local report retention (Turn off in the configuration)
• Added shared per-player and server-default language selection
• Added a categorized 54-slot language editor with search, pagination, and localized feedback.
• Improved Director menu navigation, hover formatting, Back controls, and inventory transitions.
• Language-editor saves can use compact plugin-specific old-to-new feedback
• Isolated failed debug providers so other reports still complete
• Fixed delayed Windows filesystem events reporting the same deletion twice.
• Fixed language-editor controls failing when Bukkit's active inventory differed from the cached view.

• Fixed console warning spam (every 10 seconds) caused by unsupported Windows temperature-sensor queries
• Improved Windows telemetry fallback behavior when LibreHardwareMonitor or compatible sensor support is unavailable
• Fixed Plugin API Pack runtime state being incorrectly processed and serialized as persistent configuration, preventing associated configuration and reload warnings.

• Per-world budgets Worlds are individually measured, monitor'd and reacted to.
• Smarter load management View distance, mob AI, pathfinding, activation ranges and random ticks all scale back under load and normalize when the server has enough overhead to adapt to your servers needs.
• Chunk quarantine Finds the chunks actually causing lag and isolates them.
• Hopper indexing Skips the expensive vanilla item scan around hoppers.
• Multiple Heatmaps Showing exactly where lag is coming from: entities, redstone, hoppers, chunk cost, tick spikes, player impact and where.
• Better Support for Other Plugins Gives you individual maps of every plugin loaded on your server to see what's causing the issue.
• Megamaps Line up item frames, grab react monitoring maps, and build them together to build massive react maps.
• In-game config editor with Off / Light / Balanced / High presets
• Live metrics Supported Volmit plugins such as Iris, Adapt, Wormholes, Gloss, HiddenOre and BileTools.
• Opt-in Web API Read your server's stats remotely, off by defaulted.
• Translations Added 17 translated along side English
• React Web A full browser control panel at react.volmitsoftware.com. Manage multiple servers from one place: live dashboards, pan-and-zoom heatmaps, configuration, world controls, features, tweaks, logs and an authenticated server console. Pair with [ICODE]/react web pair[/ICODE] using viewer, operator or admin roles.
• Historical telemetry Every metric is now recorded to compressed, crash-safe on-disk history. Charts go back 1 hour, 24 hours, 7 days, 30 days or all time, with averages, minimums and maximums preserved as data ages.
• Incident Center Lag events are now recorded with their actual cause, evidence, location and what React did about it.
• Monitoring-only mode [ICODE]/react monitoring-only[/ICODE] pauses every automatic feature and tweak without touching your config, while all monitoring, maps and manual commands keep working.
• Way more metrics 57 new core and runtime samplers (ground items, hostiles, villagers, block entities, chunk tickets, JVM, host disk and network, and more), full sampler coverage for every Volmit plugin.

Changed

• Complete Rewrite React has been rewritten and significantly improved.
• Compatibility Added support for Purpur, Leaf, Folia and Canvas.
• Configuration Hotloads Everything automatically hotloads upon save
• View Distance On supported platforms, you can set the view distance to dynamically update based on the servers needs.
• Mob Stacking Better mob stacking handling and no longer stacks tamed pets.
• [ICODE]/react bridge status[/ICODE] to show you what's loaded and supported based on your server
• [ICODE]/react benchmark <benchmark>[/ICODE] has been greatly improved to provide a more detailed output.
• Action Bar React is now gracefully added or removed from the action / boss bar based on priority from other plugins and plays nice.
• PlaceholderAPI rebuilt [ICODE]%react_tps%[/ICODE], [ICODE]%react_mspt%[/ICODE], [ICODE]%react_world.mspt%[/ICODE] and [ICODE]%react_sampler.<id>%[/ICODE] for every registered sampler.
• Maps The browser and sampler picker open as category hubs, walls report why a frame was rejected, colors were rebuilt on a proper palette, and rendering now pushes only changed pixels.
• Cleaner logs Routine diagnostics moved behind verbose mode and slow-tick warnings can be switched off with [ICODE]slowTickLogMode = "OFF"[/ICODE].

Fixed

• The action bar monitor erasing other plugins' titles forever after one sneak-focus (the Wormholes portal-name flicker), monitor render crashes, event timings undercounting busy listeners, ~17 silent reflection exceptions per second on idle servers, React and Adapt fighting over the same block drops, maps crashing on non-Latin languages, [ICODE]/react environment info[/ICODE] printing nothing, plain-Spigot startup failures and dozens more.
