What’s new

Among the shared updates, two fixes backported from 2026.1 are worth highlighting:

  • MPS-38409 – The new read-only-inspector style applies the read-only property to all editor cells in the inspector. When this style is applied to a cell in the main editor, the inspector becomes read-only for the inspected node while that cell is selected.
  • MPS-37407 – The Help menu on macOS now displays items with the correct height and spacing.

Check out all the updates in each particular version below:
