We are proud to announce Dotty 0.26.0-RC1. In this version, we have improved the extension methods – their syntax is now more uniform. We have also implemented local selectable instances and have done a bunch of improvements to the compiler and the language API. Otherwise, we are focusing our efforts on reducing the issue count on the issue tracker, boosting performance and improving the stability of the compiler in other ways
