7 Days to Die 3.x Mod Compatibility - What Breaks on V3.0, V3.1 and V3.2 (And What To Do)

Updated August 22, 2026. V3.2.0 is the current stable build (default Steam branch, stable since July 27, 2026). V3.2.0 is the current stable build, on the opt-in latest_experimental branch since August 19, 2026. The 3.0 infrastructure changes below are what actually broke mods on this line; 3.1 and 3.2 add smaller, specific risks on top.

V3.2.0 stable (August 26, 2026): one file decides whether your modlets survive. 3.2 is a small release, but it edits entitygroups.xml - the screamer scout groups were commented out so screamers no longer call more screamers. Any modlet that overrides entitygroups.xml will apply its own copy and can put the old chain-spawn behaviour straight back, or conflict messily. Diff it before you run this build. Three more 3.2 items matter to authors: the obsolete prefab property AllowTopSoilDecorations was removed and AllowDecorations replaces part of it; trader interiors in Rekt, Hugh and Joel now use oldWoodDoorNoHonk instead of oldWoodDoor, so a modlet editing those prefabs may be editing a door that is no longer there; and auto turrets lost stability support and wall placement, which breaks turret-on-wall prefabs and blueprints. Overhaul mods will not be on 3.2 immediately regardless - they pin a game build and recertify after a stable lands. Full breakdown: the V3.2.0 release notes.

V3.1.0 "Henpocalypse" (stable since July 27, 2026) is a content update (chicken farming) rather than a mod-infrastructure overhaul, so most 3.0-ready mods carried forward - but any mod touching sandbox options, enemy/animal spawning, or localization was worth re-testing, because 3.1.0 splits Density/Respawn into day/night and enemy/animal, adds several new sandbox options, and re-syncs localization (TFP note Fireman's Almanac Vol.2 was aligned to the new mod quality levels). Track overall status on the V3.1 reference and the 2026 Mod Status Tracker.

Every major 7DTD update breaks mods; V3.0 breaks them in documented, specific ways, because The Fun Pimps shipped real modding-infrastructure changes alongside the sandbox update. If you run a modded server or maintain a mod, here is exactly what the release notes say changes, what it means, and the safe sequence for update week.

Wondering whether your specific overhaul will even get a V3.0 build? Check the 2026 Mod Status Tracker - it lists which mods are actively maintained (and tend to update fast) versus stagnant or pinned to older versions.

The documented breaking changes

  • Localization.txtLocalization.csv. Renamed to match its actual contents. Mods shipping localization files need the rename; tooling that targets the old filename stops finding it.
  • entitygroups.xml returns to proper XML elements. The previous text-based format is still supported "currently" - which is modder-speak for migrate now, the compatibility shim will not live forever.
  • Code mods: one assembly, publicized. You now reference only the game's core Assembly-CSharp.dll, and because the code passes through a publicizer, code that overrides vanilla methods may need those overrides made public. Most C# mods need at least a recompile.
  • XUi framework overhaul (the big one for UI mods). A new XML binding system moves control from code to XML; new views (video, scrollbar, scrollview); controls.xml renamed to templates.xml; the folder renamed to XUi_InGame; the force_hide attribute removed in favor of visible; tweens controllable from XML. UI-heavy mods (HUDs, bigger backpacks with custom windows, quest trackers) face real porting work, not a recompile.

What this means for modded servers

  • Assume nothing survives update day. The XUi rework alone touches most popular server-side UI conveniences. The usual wave applies: big mods within days, mid-size within weeks, abandoned never.
  • Overhauls will lag longest. Darkness Falls-class total conversions touch entitygroups, localization, code, and UI at once - every changed surface. Overhaul servers should plan to stay on V2.6 until their overhaul publishes a V3.0 build (saves do not load backward, so the move is one-way).
  • Some mods become obsolete - in a good way. A real fraction of the server-mod ecosystem exists to do what the 150 sandbox options now do natively (loot abundance, zombie speeds, headshot rules, death penalties). Before porting a settings mod, check whether V3.0 just shipped it as a checkbox.
  • The safe sequence: export your mod list → classify critical / nice-to-have / replaced-by-sandbox-options → wait for critical mods' V3.0 releases → test on a copy → then move the community save. Our SandboxCode guide covers the config side of the same migration.

For mod authors: the priority order

  • Week one: rename localization, recompile against the publicized assembly, fix any override visibility errors - that revives non-UI mods fastest.
  • Week two: entitygroups to proper XML (do not lean on the deprecated text format).
  • The long tail: XUi ports. The new binding system is documented on the official wiki, and the consolidation (shared attributes across views, rects over panels) genuinely reduces duplication once ported - the pain is front-loaded.

Timing

V3.0 reached stable on June 29, 2026, and V3.2.0 is the current stable build since July 27. V3.2.0 is the current stable build. Mod authors can port against an experimental branch as soon as it appears, which historically means the big modlets are ready near stable day; overhauls take far longer.
