github mui-org/material-ui v5.0.0-alpha.13

Oct 17, 2020

Big thanks to the 25 contributors who made this release possible.
Here are some highlights ✨:

  • 📦 Ship modern bundle (#22814) @eps1lon.
    This is a significant update to the browsers supported by Material-UI.
    The previous policy was defined 2 years ago, and the landscape has evolved since then. The package now includes 4 bundles:

    1. stable (default, formerly esm) which targets a snapshot (on release) of > 0.5%, last 2 versions, Firefox ESR, not dead, not IE 11"
    2. node (formerly default) which targets a snapshot (on release) of maintained node versions
    3. legacy (new) which is stable + IE11
    4. modern (formerly es) which targets the last 1 version of evergreen browsers and active node (currently that is 14

The change yields a 6% reduction in bundle size 📦 (Babel only).
In the coming weeks, we will refactor the internals to take advantage of the new browser capabilities that dropping these older platforms allows. For instance, we might be able to remove the span we render inside the <Button> to work around Flexbug #9.

Check the updated Supported platforms documentation and new "minimizing bundle size" guide.

If you target IE11, you need to use the new bundle (legacy). We are treating IE11 as a second class-citizen, which is a continuation of the direction taken in #22873.

  • 🚀 Improve the internal benchmark suite (#22923, #23058) @mnajdova.
    This was a prerequisite step to improve the system. We needed to be able to measure performance. After #22945, we have measured that the Box component is x3 faster in v5-alpha compared to v4.
  • ✏️ A new blog post: Q3 2020 Update (#23055) @oliviertassinari.
  • 🐙 Migrate more tests to react-testing-library @deiga, @Morteza-Jenabzadeh, @nicholas-l.
  • And many more 🐛 bug fixes and 📚 improvements.
