What’s new

Faster native worlds and protected custom assets

Build 184 makes native worlds faster and smoother, improves AI traffic, and lets servers protect custom model files.

For players

• Native worlds can now load for the first time without restarting GTA.
• Previously downloaded worlds load much faster and automatically recover from damaged cache files.
• AI traffic follows lanes, intersections and one-way roads more reliably.

For creators and server owners

• Servers can now encrypt downloadable DFF, TXD and COL files.
• The new engineReplaceEncryptedModel function securely loads these protected models.
• Clients and servers must both use build 184 because this update changes the Neon network protocol.

What’s new

Neon Identity, DevTools and native-world improvements

Build 183 makes Neon Identity simple to enable on community servers, adds structured DebugScript 4 diagnostics, expands native AI and story tooling, and fixes traffic, shadows, dialogs and native-world transitions.

For players

• Disconnect, confirmation and other system dialogs now keep their Close, Cancel and Confirm buttons visible and readable.
• Invisible peds and the local player no longer leave blob or dynamic shadows behind when their alpha is zero.
• Synchronized native traffic no longer turns into an impossible direction after joining a one-way road.
• Switching between native world packs now restores GTA streaming, collision and model state more reliably, including repeated same-session switches and safe loader restarts.

Server owners and Neon Identity

• Enable Neon authentication with a single neon_auth setting: disabled, optional or required. No server ID or public key needs to be provisioned manually for the official service.
• The server creates a persistent cryptographic identity, proves control of its public ASE endpoint and renews its Identity registration automatically.
• Existing mtaserver.conf files receive the new setting in disabled mode automatically, while complete legacy and custom Identity configurations remain supported.
• Required mode fails closed while registration is unavailable; optional mode keeps ordinary connections available without exposing an unverified identity.
• The cancellable onPlayerConnect event now appends the verified Neon account ID and Discord ID when available, allowing resources to apply account policy before the player joins.

For creators

• DebugScript level 4 opens a structured CEF diagnostics interface with client/server context, filtering, search, occurrence counts, history and export tools.
• The complete DebugScript 4 frontend is now included in both clean installations and installer-based updates.
• Use setPedNavigateTo to run GTA node-route navigation for synchronized peds, including native building-collision recovery.
• New native task primitives cover ped drive missions, ped physical proofs, vehicle straight-line distance and recorded-playback speed.
• Reusable task-cohort and recorded-playback foundations support authoritative multi-actor missions, ownership handoff and synchronized observers.
• The source repository, rather than the downloadable server package, now includes cooperative Sweet & Kendl and OG Loc reference missions plus bounded native navigation, freeroam traffic and story validation resources.

Development tooling

• The new Neon CLI provides a deterministic catalogue of inherited MTA APIs and Neon additions, project-local contracts, focused context packs and side-specific LuaLS metadata.
• Closed scenario evidence, project verification and tamper checks make automated development results reproducible without granting arbitrary shell access.
• An authenticated loopback runtime supervisor supports read-only comparison by default and explicitly bounded resource or scenario mutations when enabled.
• Vehicle-audio documentation now explains the prepared Assetto Corsa or Soundize bank workflow and synchronized RPM, throttle, gear and backfire behavior.

What’s new

Missing client assets restored

Build 181 repairs Definitive radar and Project2DFX data omitted from build 180 installations and strengthens installer validation.

Players and fixes

• Updating from build 180 now installs the missing Definitive Edition radar textures.
• Selecting the Definitive Edition radar no longer silently falls back to GTA's original renderer because of missing packaged assets.
• Project2DFX distant lights now load their complete definition set instead of falling back to GTA's embedded effects.

Release infrastructure

• The release workflow now verifies critical data hashes and refuses any staged client file omitted from the final installer.

What’s new

New menus, faster downloads and new Lua tools

Build 180 replaces the main client menus, speeds up resource downloads and adds APIs for maps, collision, physics, effects and GTA world systems.

For players

• The main menu, server browser and settings menu have been rebuilt.
• Settings now covers gameplay, graphics, audio, controls, interface, Neon features and advanced options.
• Paste an IP address, hostname, mtasa:// link or mtaneon:// link into the server browser to connect directly.
• Use Copy link on a selected server to share its mtaneon:// address.
• Connection errors, password requests and update prompts now appear over the new menu instead of being hidden behind it.
• Resource files can download in parallel, reducing join time when a server sends several files.
• Radio selection and saved GTA volume levels now restore correctly.
• Radar icons now stay below the player marker.

For creators

• Load SA-MP Pawn map exports directly, including material replacements.
• Create collision shapes from Lua or replace a model's collision data without shipping a .col file.
• Track and control GTA world objects, or give MTA objects synchronized GTA rigid-body physics.
• Place GTA foliage anywhere and create synchronized fires that can follow an element.
• Create and control bird flocks and synchronized ropes. Ropes support all eight GTA rope types and cargo attachment.
• Read, edit, add or remove model 2DFX entries, and create break effects from an object's own geometry without editing its DFF.
• Enable GTA ambient civilians, gangs, police patrols, dealers and couples through the native population runtime.
• Read native radio playback state and the object streaming quota split from Lua.

Servers and fixes

• Replacing a resource file now invalidates its old cached checksum instead of reusing stale data.
• Reconnect and server-connection UI state no longer gets stuck behind old CEGUI windows.
• Secondary clients skip CEF initialization, and multi-client windows tile without resizing GTA.
