Apple vient de relâcher la 28e preview de Safari Technology. Cette nouvelle mouture apporte comme à son habitude une meilleure stabilité et plusieurs corrections de bugs. Nous vous rappelons que cette version ne remplace en aucun cas votre navigateur Safari actuel.

Les changements de cette version concernent l’accessibilité, le CSS / JavaScript, le WebGPU, les API Web, Web Inspector, le réseau, et bien plus à découvrir à cette adresse. Apple a également corrigé de nombreux bugs pour l’occasion.

Voici le Release 29
