Stencil 3.0 Beta, the latest version of the web component compiler, has been released for testing, bringing significant changes aimed at paving the way for future development. The update includes breaking changes such as dropping support for Node 12 and deprecated features for older browsers like Safari 10 and IE 11, with corresponding flags marked for eventual removal. The dist-custom-elements-bundle output target has been replaced by dist-custom-elements to improve treeshaking and reduce bundle sizes, with a migration guide provided for users. The Stencil team has been restructured to deepen their understanding of the compiler's internals, ensuring sustainable development and knowledge sharing within the team. Users are encouraged to test the beta version and report any issues, with the testing phase expected to extend due to the holiday season.
