We added a new feature of highlighting the table of contents on the right side as you scroll the docs pages with the great work by @tusharf5. A few bugs affecting local development were also fixed. More notably, the blog's left sidebar will not hide the post titles when docsSideNavCollapsible is turned on. This is a bugfix/backward-incompatible change depending on how you view it, but probably nobody wanted that collapsing behavior on the blog sidebar in the first place.
We also welcome @wgao19 to the core team! She'll be helping us with Docusaurus 2 work leveraging on her experience writing documentation and CSS!
