1.20.1

[1.20.1] - 2026-10-05

Fixed

• Fixed the Input Actions editor window's unsaved-changes handling on close: it now uses the Editor's built-in save prompt (including on Editor quit), auto-saves pending changes when the window is closed with auto-save enabled, and prompts instead of silently dropping changes if an auto-save fails (e.g. version control refused the checkout). UUM-154808
• Fixed misaligned labels in the Input Actions editor properties pane. UUM-154536
• Fixed a single click producing two simultaneous touches when the Device Simulator view is open and "Simulate Touch Input From Mouse or Pen" is enabled in the Input Debugger; Touch Simulation now suppresses its events while a Device Simulator view is open [UUM-153420]
• Fixed the search field in the "Add supported device" popup (Input System Package Settings > Supported Devices > "+") drawing flush against the popup's left edge with no left margin, unlike its right-side spacing; it is now inset to match UUM-150217
• Fixed the "Supported Devices" list in the Input System Package Settings sitting flush against the panel edge with no left/right margin, unlike the surrounding fields; it is now inset to line up with the other settings controls UUM-150207
• Fixed the Inspector help button for a selected .inputactions asset ("Open Reference for Input Action Importer") opening a missing documentation page; it now links to the Action Assets manual page UUM-149518
• Fixed an OverflowException when creating a control scheme (or other named item) whose all-numeric name exceeds Int32.MaxValue, which previously discarded the entered name and fell back to the default UUM-145766
• Fixed the Input Actions editor window logging a "Failed to load asset" exception on editor startup when its saved window layout was restored in a project where the referenced asset GUID did not resolve; the window now closes quietly instead UUM-144318
• Empty foldouts are no longer shown for processors and interactions that have no settings (e.g. "Invert") UUM-144325
• Fixed the Input Actions editor toolbar buttons being clipped when the Action Properties panel grew tall enough to show a scrollbar
• Fixed the Control Schemes dropdown in the Input Actions editor continuing to display a deleted scheme's name after the last control scheme was removed, instead of resetting to "No Control Schemes" until the asset was saved or the editor reopened. UUM-141563
• Fixed the Input Debugger window (Window > Analysis > Input Debugger) being resizable arbitrarily small until its toolbar and device/action/layout tree view were no longer usably visible; it now enforces a minimum window size UUM-137119
• Fixed the Action Maps list in the Input Actions editor losing keyboard focus after deleting a map, so that Delete, Duplicate, and arrow-key navigation kept working on the auto-selected replacement map without requiring an extra click UUM-147152
• Fixed the Device Simulator plugin keeping the real mouse and pen disabled while working in other Editor windows. Conflicting native Mouse/Pen devices are now only disabled while the Simulator window is focused and re-enabled as soon as focus moves elsewhere UUM-145509.
• Fixed the Input Actions editor in Project Settings losing the selected action or binding when opening the control picker from the Path field UUM-151771.
