Other B4A v13.7 BETA - targetSdkVersion = 36 + Edge to Edge - Erel Jul 30, 2026 (33 reactions) I'm happy to release a new BETA version of B4A.

This is a feature that will be mandatory at some point in the future (maybe 2 years from now) and it goes together with other upcoming requirements of handling...
