v1.0.0

First stable release. Unity 6000.0.53f1 or newer; every Inspector feature works in both IMGUI and UI Toolkit. The 1.0.0-rc.* prereleases and their notes are on GitHub Releases.

Added

• SerializableType and SerializableMonoScript store a System.Type in a component or an asset; [TypeSelector] picks it in the Inspector from compatible types.
• SerializeReference Selector picks the class of a [SerializeReference] field and carries compatible data over when the class changes.
• ComponentTypeSelector changes an added component to a derived class without losing shared field values.
• Project References finds missing [SerializeReference] references and SerializableType names across the project and repairs them in groups; the build and CI checks catch new ones.
• EnumValues maps enum keys to values that you edit in the Inspector, flags included.
• this.Marker() opens a profiler marker named after the type, the method and the line of the call; a source generator builds it.
• Analyzers AFT0001–AFT0014 report [TypeSelector] and this.Marker() misuse in the IDE.
• VisualElement Extensions set element properties, styles and events in a chain.
• SerializedProperty Extensions update the object, write a value and apply the change in one chain.
• Editor Helpers: GetDisplayName() and GetDisplayNameWithIndex() label objects and components with readable names.
• The FastTools window (Tools → Aspid 🐍 → FastTools) with the Welcome, Asset References, Project References and Settings tabs, and themes for the FastTools windows.
• Samples for every feature, and Agent Skills that teach a coding agent to write code with FastTools.
