A huge release (the first one in 1.5 years), focused on bug fixes, major reliability and accessibility improvements, cleaning up legacy code, and numerous improvements to documentation, development workflow and release process. A culmination of hundreds of contributions, and a preparation for bigger changes to come. πŸƒ

From now on, releases will become much more frequent. Thanks to our amazing community for all your help and patience. β€οΈπŸ™ This release is dedicated to Ukrainian fight for freedom and democracy against the Russian invasion πŸ‡ΊπŸ‡¦ (see how you can support Ukraine here).

Please help us test the beta version β€”Β if no critical regressions are discovered, v1.8.0 final will follow in a few days.

Special thanks to @johnd0e who revived Leaflet development after long stagnation and made the biggest contributions, @Falke-Design for doing the bulk of the work organizing development and preparing the release, @Malvoz for his accessibility contributions, and @jonkoops for help with workflow automations. ❀️
