v4.5.2

Oct 28, 2019

Big thanks to the 48 contributors who made this release possible!

Here are some highlights ✨:

• 🔍 Introduce a new Autocomplete component in the lab to support the autocomplete, combobox and multi-select use cases (#17037) @dreamsinspace.

  This new component will replace the third-party integration examples once it graduates from the lab to the core.
  It was one of the most requested features (by the number of 👍 on the corresponding issue).
