With more coming soon
Automatic Updates and Project Browser are two key upcoming features for Drupal 10 that are being built as contributed modules.
1. The automatic Updates module applies patch-level updates to Drupal core in a separate, sandboxed copy of your site, to keep you up and running until the update is entirely ready to be deployed. It can detect and report problems at every stage of the update process, so you don't have to find out about them after an update is live. It automatically detects database updates in an incoming update and helps you run them during the process.
2. Project Browser makes it easy for site builders to find modules and themes. Once a project is selected, instructions are provided on how to install the extension on your site. The browser lives inside the Drupal site itself on a new Browse tab under Extend. This means you don't need to leave your site in order to look for projects.
