Development

For the past week @ry was refactoring build and CI pipeline and now Deno no longer uses `tools/build.py` instead everything is built using `cargo build` (#2865)

Registry

Last week I told you about directory listing in registry, unfortunately there were wild 503s appearing now and then. This issue should be fixed now.

Check out example directory listing (oakserver)
