The following features have been added to Maya LT 2019.1 Update:
Improvements to Outliner performance
A new Interface Preference, Outliner, has been created to let you increase the speed when expanding or selecting objects in the Outliner. Previously, working with object sets that contain a large number of faces could become slow.
Activate the Outliner option in the Interface Preferences to increase performance by limiting state change messages.
Booleans improvements
Boolean tools will no longer create or modify invalid meshes, which addresses a Top 10 CER crash in previous versions.
Note:
You may see differences when reading in files prior to this update, since invalid meshes will no longer appear in the scene.
