Autodesk Maya 2019.1 was a point update primarily focused on performance improvements
: The update resolved critical UI and viewport issues, including errors related to motion trails and specific scripting tool behaviors in the Maya Embedded Language (MEL) . Technical Specifications and Requirements Autodesk Maya 2019.1
The node-based shading environment got a search bar that actually works instantly. You can now type "metal" and all Standard Surface nodes with "metal" in their name are highlighted. Additionally, the render preview swatches now update using the GPU (via Viewport 2.0) rather than rendering a separate mental ray image, making material tweaks instantaneous. Autodesk Maya 2019
Additionally, the 2019 release cycle saw better integration of the workflow (in later updates), but in 2019.1 specifically, the focus remained on ensuring that what you see in the viewport matches your final render more accurately, particularly when using Arnold.

A more intuitive interface with improved layout tools and a cleaner look to help you get through texturing faster.
The single most transformative feature of is the Parallel Evaluation Mode . Traditionally, Maya evaluated node graphs—connections between constraints, deformers, and transforms—on a single CPU thread. This meant that complex rigs with hundreds of controllers (like detailed facial rigs or full-body mechanical setups) would choke the main thread, causing stuttering playback.
