Release 2026.06

This is the changelog since version 2025.06 until version 2026.06.12, which was released on 2026-07-14.

Caveats

• UTF-8 file paths are now supported.
• some file accesses are now case-sensitive.
• rmlUI version used 6.0 → 6.2
• ARM64 architecture builds now have nominal support.
• /aicontrol is now blocked by default. Call /aiCtrl PlayerName or /aiCtrlByNum 123 to enable.
• script:AimWeapon now receives unit-relative heading and pitch, rather than world-space. This means units angled on slopes will receive different values.
• heading cast to radians will now return [-pi; +pi) rather than [0; tau).
• minor Lua env sandboxing changes, see the “Lua environment sandboxing” section below.
• always output logs to stdout.
• removed CSphereParticleSpawner particle class. Identical to CSimpleParticleSystem.
• archive cache version 20 → 21.

Features

RmlUi

• rmlUI version used 6.0 → 6.2
• add datamodel support for pairs: pairs(dm_handle)
• add datamodel support for ipairs: dm_handle:__ipairs()
• support for accessing the underlying datamodel table with dm_handle.__raw()
• allow datamodel self-referential assignments such as dm_handle.property = dm_handle.another_property
• support for retrieving datamodel property length: dm_handle.property.__len()
• fix datamodel array access
• fix data-value binds in rml elements
• added RmlUi.GetDocumentPathRequests(string docPath) -> {"filePath", "filePath", ...} which tracks all of the files opened by an RmlUi LoadDocument call
• added RmlUi.ClearDocumentPathRequests(string docPath) -> nil to clear tracked LoadDocument files

Radar icon Lua API

• added Spring.SetUnitIcon(unitID, string? iconName). Pass nil to reset to default.
• added Spring.GetUnitIcon(unitID) → string iconName.

Minimap callins

• added wupget:MiniMapRotationChanged(rotation, previousRotation) unsynced callin. In radians.
• added wupget:MiniMapGeometryChanged(x, y, sizeX, sizeY, prevX, prevY, prevSizeX, prevSizeY) unsynced callin. In pixels.
• added wupget:MiniMapStateChanged(isMinimized, isMaximized, isSlaved) unsynced callin.

Misc

• UTF-8 file paths are now supported.
• some file accesses are now case-sensitive.
• /aicontrol is now blocked by default. Call /aiCtrl PlayerName or /aiCtrlByNum 123 to enable.
• script:AimWeapon now receives unit-relative heading and pitch, rather than world-space. This means units angled on slopes will receive different values.
• heading cast to radians will now return [-pi; +pi) rather than [0; tau).
• add Spring.SetCheatingEnabled(bool).
• add Spring.SetGodMode(bool? controlAllies, bool? controlEnemies).
• large QTPFS perf improvements.
• always output logs to stdout.
