RELEASES

Scala.js 1.16.0

The biggest highlight of this release is that we added a Scala.js-specific minifier. When combined with a general-purpose JavaScript minifier, our minifier should bring most of the code size benefits of the Google Closure Compiler when the latter cannot be enabled, notably when emitting ECMAScript modules.
Scala.js contributors (@scala_js)
tapir 1.10.0

New version brings more performance improvements, as well as codegen enhancements.
