Rust Spring Clean Update (April 2026): What Server Admins Need to Know

The Spring Clean update dropped on April 2, 2026 (6 PM UTC) alongside the monthly forced wipe. This patch brings a mix of new building pieces, a renewable electricity source, a controversial shield rebalance, a complete F1 console overhaul, and significant server-side memory savings. Here is everything that matters for dedicated server operators.

Branch: Stable (main). Force-update your server with +app_update 258550 validate via SteamCMD. Clients on the old build cannot connect.

Key Changes at a Glance

New Armored Ladder Hatch (square and triangle) — 1,000 HP, Tier 3 Workbench
Water Wheel — passive electricity from rivers and oceans
Shield hitbox nerf — reduces the "shield meta" dominance in PvP
~600 MB RAM saved on dedicated servers by stripping unused meshes
2.7 GB disk space reclaimed from the server build
Full F1 console UI overhaul with scrollable command/convar browser
Parallelized AntiHack and Network Streaming via UsePlayerUpdateJobs 3

Armored Ladder Hatch

The armored ladder hatch is a direct upgrade from the metal ladder hatch, designed for players who want maximum vertical-access durability. It unlocks at Tier 3 Workbench and comes in both square and triangle frame variants.

Property	Metal Ladder Hatch	Armored Ladder Hatch
Health	250 HP	1,000 HP
Raid cost (rockets)	~2 rockets	~5 rockets
Raid cost (C4)	~1 C4	~2 C4
Workbench tier	Tier 2	Tier 3

Admin tip: The armored hatch does not require any new server-side configuration. It uses existing building-tier decay rules. If you run a custom decay.scale, it applies identically to armored hatches.

Water Wheel: Passive Renewable Power

Water wheels are a new deployable that generates electricity passively from flowing water. Place them in rivers for consistent output, or in the ocean for variable power that fluctuates with the tides.

How It Works

Deployable on any water surface — rivers provide steady output, oceans are inconsistent
Connects to the standard electrical wiring system
No fuel cost — truly passive generation
Multiple wheels can be daisy-chained for higher throughput

Admin note: Water wheels use the same entity budget as other deployables. On high-pop servers where entity count is a concern, monitor entity.count via RCON after the wipe settles. River bases may become more popular this month.

Server Memory & Disk Savings

Facepunch made a significant optimization to the dedicated server build process. Most mesh data has been stripped from the server binary unless a mesh is required for a collider. The impact:

Metric	Before Spring Clean	After Spring Clean
Runtime RAM usage	Baseline	~600 MB lower
Disk footprint	Baseline	~2.7 GB smaller

This is a free performance win that requires no configuration changes. Servers with tight RAM budgets (e.g., 8 GB VPS instances) will benefit the most.

Network & AntiHack Parallelization

The UsePlayerUpdateJobs server variable now recognizes level 3, which parallelizes both AntiHack validation and Network Streaming updates using UniTask. On multi-core servers this reduces main-thread load during peak player counts.

Caution: Level 3 is new and may exhibit edge cases on unusual hardware configurations. Test on a staging instance before applying to your main server. Set via server.cfg:

# Enable parallelized player updates (new in Spring Clean)
UsePlayerUpdateJobs 3

Shield Hitbox Nerf

The riot shield's hitbox has been reduced, making it harder to hide behind and easier for opponents to land shots around the edges. This directly impacts PvP balance on servers running vanilla combat settings.

For servers with custom damage modifiers or arena plugins, the shield remains functional but less dominant. No server-side convar changes are needed — this is a client/server shared hitbox change.

F1 Console Overhaul

The in-game F1 console received a complete UI rewrite. While this is primarily a client-side improvement, it also benefits server admins who use the console for quick RCON commands:

Scrollable item and command browser
Full convar menu with explanations for each setting
Improved search and autocomplete
