EdgeDB's fourth and final release candidate, Procyon, has been released with minimal changes, primarily focusing on bug fixes and a non-breaking simplification to the for loop syntax, as the team prepares for the EdgeDB 1.0 launch on February 10th, 2022, during a livestreamed event. The release reintroduces Windows support for the CLI by using Windows Subsystem for Linux (WSL) instead of Docker, ensuring that all documented workflows function seamlessly. New users are encouraged to follow a 10-minute Quickstart guide for installation and initial setup, while those upgrading from earlier versions must follow specific procedures, including manual dump/restore for versions RC2 or earlier and straightforward CLI commands for RC3. The upcoming launch is positioned as a significant milestone, heralding the post-SQL era, and interested parties can register for the live event at lu.ma/edgedb. For those new to EdgeDB, various resources such as the interactive tutorial and the Easy EdgeDB e-book are available to provide a comprehensive learning experience.
