+
+
+We are pleased to announce the release of Scala.js 1.10.1!
+
+This release mostly contains bug fixes and optimizations.
+It also updates the version of the Scala standard library to 2.12.16 for 2.12.x versions.
+
+Read on for more details.
+
+<!--more-->
+
+## Getting started
+
+If you are new to Scala.js, head over to [the tutorial]({{ BASE_PATH }}/tutorial/).
+
+If you need help with anything related to Scala.js, you may find our community [in `#scala-js` on Discord](https://discord.com/invite/scala) and [on Stack Overflow](https://stackoverflow.com/questions/tagged/scala.js).
+
+Bug reports can be filed [on GitHub](https://github.com/scala-js/scala-js/issues).
+
+## Release notes
+
+If upgrading from Scala.js 0.6.x, make sure to read [the release notes of Scala.js 1.0.0]({{ BASE_PATH }}/news/2020/02/25/announcing-scalajs-1.0.0/) first, as they contain a host of important information, including breaking changes.
+
+This is a **patch** release:
+
+* It is backward binary compatible with all earlier versions in the 1.x series: libraries compiled with 1.0.x through 1.10.0 can be used with 1.10.1 without change.
+* It is forward binary compatible with 1.10.0: libraries compiled with 1.10.1 can be used with 1.10.0 without change.
+* It is backward source compatible with 1.10.0: source code that used to compile with 1.10.0 should compile as is when upgrading to 1.10.1.
+
+In addition, like Scala.js 1.10.0:
+
+* It is forward binary compatible with 1.8.x and 1.9.x, but *not* 1.7.x: libraries compiled with 1.10.1 can be used with 1.8.x and later, but not with 1.7.x or earlier.
+* It is *not* entirely backward source compatible with 1.9.x: it is not guaranteed that a codebase will compile *as is* when upgrading from 1.9.x or earlier (in particular in the presence of `-Xfatal-warnings`).
+
+As a reminder, libraries compiled with 0.6.x cannot be used with Scala.js 1.x; they must be republished with 1.x first.
+
+## Miscellaneous
+
+### Optimizations
+
+Scala.js 1.10.0 brought some optimizations with respect to closures.
+Scala.js 1.10.1 expands on these optimizations with the following improvements:
+
+* When a closure captures a variable that ends up being constant-folded, the constant is propagated inside the closure, and the capture parameter is removed.
+* Most closures that are not declared within a loop do not need an IIFE (Immediately Invoked Function Expression) anymore, even when they actually capture some variables.
+
+## Bug fixes
+
+Among others, the following bugs have been fixed in 1.10.1:
+
+* [#4684](https://github.com/scala-js/scala-js/issues/4684) Unit JS default param makes compiler crash with "Found a dangling UndefinedParam"
+* [#4675](https://github.com/scala-js/scala-js/issues/4675) ES2021 not supported in fullLinkJS
