Miew 0.10.0 (January 25, 2022)

Summary

The main goal of this release is to close technical debt and prepare for future expansion.
The foundation has been laid for the implementation of various presentation layers. As part of this release, in particular, React support is implemented in the miew-react package, which is also available via NPM.

BREAKING CHANGES!

The miew package now contains named and default exports.
If you use our application as a minified miew.min.js file, then you can now access the Miew constructor only through the miew namespace as follows:

const { Miew } = miew
const viewer = new Miew({ load: '1CRN' })
