Bevy Engine 0.15 with Required Components, Entity Picking, and more

Release Notes: https://bevyengine.org/news/bevy-0-15/ Migration Guide: https://bevyengine.org/learn/migration-guides/0-14-to-0-15/ Bevy is a data-driven game engine built in Rust and Bevy 0.15 is officially released. This is the end of a multi-week release candidate process so unless you're relying on a third party crate that hasn't made a release, you can update today. We've got a ton to talk about but I want to start by pointing out the official blog post which lists the full extent of the changes, including links to the relevant Pull Requests, as well as the migration guide which covers everything you could want to know about upgrading your applications. ## Chapters 00:00 Bevy 0.15 is out now! 00:30 Required Components 01:35 Rendering 01:41 Chromatic Aberration 01:58 Order Independent Transparency 02:12 Visibility Bitmask Ambient Occlusion 02:35 Volumetric Fog 03:03 Retained Render World 03:32 Entity Picking 04:07 Curves 04:55 Animation 05:33 Bevy Remote Protocol 05:50 Observers 06:15 bevy_ui 06:26 cosmic-text 06:55 and more
