AntiSpoof Pro - Deep Probe Engine v1.5.0

Changelog (1.4.9 → 1.5.0)​

Highlights

• Protocol-Level Probe Freezing: Added a high-performance packet-level interceptor to our probe-freeze system. This actively intercepts and drops movement and action packets at the protocol level (via PacketEvents) while a player is undergoing verification. Features a smart 250ms cached decision map to eliminate performance overhead on the server thread.
• New Whitelist Mode — Only Listed: Added an ONLY_LISTED option to the channel whitelist modes. This allows players to connect with any subset of whitelisted channels, but instantly flags them if they register a single unlisted/extra channel.
• Protocol-Version Compatibility Fix: Improved compatibility for active verification probes on mixed-version networks, ensuring backend payloads generate in the server's native format before remapping by protocol translation layers (like ViaVersion).
• Complete LabyMod Permissions Suite: Added full support for LabyMod integration permission nodes, covering GUI menus, administrative inspection commands, and custom bypass rules.
• Unified PlaceholderAPI System: Overhauled our PlaceholderAPI expansion to dynamically resolve all %antispoof_...% placeholders through our master parsing service, ensuring complete support for all new client variables.
• Offline Webhook Persistence: Reworked data-handling within our Discord integration to retain player client snapshots during disconnects. This allows delayed webhooks to render complete client and mod details even if the player goes offline or gets banned before the webhook fires.
• Feather API Connection Recovery: Added a multi-tick connection recovery loop on join to successfully retrieve Feather API player data if the initial hello packet is delayed or dropped.
• Dynamic GUI Grid Realignment: Polished the Player Info GUI to cleanly balance and position up to four active client integration buttons (Lunar, Badlion, Feather, LabyMod) dynamically.

A config update is HIGHLY recommended for this update so new sections/files are generated correctly. You can use /as config update.

This milestone release introduces protocol-level packet freezing, a new 'Only Listed' channel whitelist mode, offline webhook persistence, protocol-version compatibility fixes, and full LabyMod permission support.

Changelog (1.4.8 → 1.4.9)​

Highlights

• All-New LabyMod Client Integration: Expanded our supported client suite by adding deep, native integration for LabyMod.
  • Full support for LabyMod 4 Server API events with a seamless fallback to legacy LabyMod API events.
  • Added active addon retrieval, brand spoof checks, and permission-based bypass nodes.
  • Supports server-side addon controls to automatically disable specific LabyMod addons.
  • Dedicated clients/labymod.yml configuration, GUI rule management, and PlaceholderAPI variables.
• Badlion Mod API Delivery Overhaul: Re-engineered how Badlion restriction payloads are sent. Reduced default restriction delay ticks to 1 for much faster, early-handshake enforcement.
• Dynamic GUI Layout Centering: Redesigned the Player Info GUI to dynamically center and reposition active client integration buttons (Lunar, Badlion, Feather, LabyMod) depending on how many active client connections are registered for the player, ensuring a perfectly balanced layout.
• Update Checker Patches: Redirected update notifications and console check logs directly to our BuiltByBit resource page.

A config update is HIGHLY recommended for this update so new sections/files are generated correctly. You can use /as config update.

This release introduces full LabyMod integration (addons, spoof checks, and restrictions), overhauls Badlion packet delivery, dynamically centers GUI layouts, and polishes update notification paths.

Changelog (1.4.7.3 → 1.4.8)​

Highlights

• Robust Dynamic Version Resolution: Completely reconstructed the underlying update checker to parse and compare version numbers of arbitrary length (such as four-part micro-patches like 1.4.7.3). This replaces the legacy three-digit limitation with a fully dynamic, part-by-part integer list comparator, ensuring administrators always receive timely and accurate update alerts.
  
• Stability & Notification Cleanup: Refined in-game update notifications for administrators and optimized background network checks.

A config update is not required if you are updating from 1.4.7.3.

This hotfix overhauls the update-checking system to support multi-part version strings, ensuring accurate update notifications for all future minor patches.

Changelog (1.4.7.2 → 1.4.7.3)​

Highlights

• All-New Client Integration Suite (Opt-In): Added native, deep support for leading competitive clients (Lunar Client, Feather Client, and Badlion Client) to enforce server-side restrictions and manage modular client rules.

  • New lunar.spoof-check, feather.spoof-check, and badlion.spoof-check configurations.
  • Flags and punishes accounts attempting to spoof client brand metadata.
• Dedicated Client Mod & Config GUIs: Added intuitive, beautiful new in-game menus to inspect reported client mods, active rules, and restriction states.
  • Interactive ClientModsGUI to browse a player's installed mod details (where supported).
  • New ClientConfigGUI to toggle rules, restrictions, and spoof checks on the fly.
• Advanced Client Inspection Commands: Added the /as client command suite for in-depth staff investigations.
  • /as client <lunar|feather|badlion> <player> displays a player's detailed handshake, version, platform, and reported mod inventory.
  • /as client <client> list lists all active online players running the specified client.
  • /as client <client> refresh <player|*> manually triggers a fresh mod-report request.
  • /as client <client> search <mod> searches online players for specific mod IDs.
• Modular Client Configurations: Client-specific rules and settings have been moved out of the core config into clean, easy-to-manage sub-files (clients/lunar.yml, clients/feather.yml, and clients/badlion.yml).
  
• Expanded Discord & PlaceholderAPI Support: Exposed extensive new placeholders (such as %antispoof_is_lunar% and %antispoof_lunar_mods_count%) and added rich metadata integration for Discord webhook alerts.
  
• Internal Loader & Stability Adjustments: General optimizations to the startup pipeline, file mapping, and permission checks to ensure seamless performance under heavy load.

A config update is HIGHLY recommended for this update so new sections/files are generated correctly. You can use /as config update.
