Rust Release Changelog - 1.98.0
Hi, hello. Welcome to another video in the Rust Release Changelog Series In this episode, we are Chris Biscardi (https://bsky.app/profile/chrisbiscardi.bsky.social) Cameron Dershem (https://bsky.app/profile/pinkhatbeard.com) Pete LeVasseur (https://bsky.app/profile/petelevasseur.com) from the Rust Content Team. Our team was founded to help explore and publish more of what's happening within and from the prospective of the Rust Project itself. Recently we've observed many questions regarding things that we've taken for granted that everyone knew about Rust. This lead us to realize that most everyone on our team has been around since the early days when it was easy to keep up with everything in the Project, but as we grow, it's completely unreasonable to expect anyone to be able to 'catch up' with more than a decade of knowledge. Our hope is to use this series to both surface voices within the Project and to give the community more insight into how things work.
