In this release, we’ve prioritized optimizing the Handsontable build process, leading to a considerable reduction in package size and a positive impact on the code’s performance. Additionally, we’ve resolved numerous bugs, including problems with moving rows, column resizing, and some more.

Optimizing Handsontable builds

Handsontable 13.1.0 brings an optimization to its build process. This involves refining Babel’s browser targets and upgrading Webpack to v5. By removing the polyfill for unsupported browsers, the output file sizes have been reduced even by 22% compared to version 13.0.0, saving you valuable bandwidth. Check it yourself on Bundlephobia.
