Boa v0.21 is now available! After 9 months of development we are very
happy to present you the latest release of the Boa JavaScript engine.
Boa makes it easy to embed a JS engine in your projects, and you can
even use it from WebAssembly. See the about page for more
info.

In this release, our conformance has grown from 89.92% to 94.12% in the
official ECMAScript Test Suite (Test262). Our growth in conformance is
driven by increased conformance for Temporal (discussed further in the blog post)
with the rest of the development effort being focused on performance,
internal improvements, and runtime features. We will continue to implement
more of the specification; however, as of the current moment, Boa's conformance
aligns with the major browser engine's conformance, so future increases
in conformance will be minor or bound to the feature size going forward.

You can check the full list of changes here, and the full
information on conformance here.
