Dropping support for non-canonical downloads (
from to on 27 Oct 2023 18:06 +0000


We want to improve the reliability and performance of crate downloads.

“Non-canonical downloads” (that use URLs containing hyphens or underscores where the crate published uses the opposite) are blocking these plans.

On 2023-11-20 support for “non-canonical downloads” will be disabled.

cargo users are unaffected.

For a second I read non-canonical as non-Canonical and I became angry towards the Ubuntu organization on 28 Oct 2023 18:23 +0000

Seems like they could maintain non-canonical lookups by normalizing all crate names to use underscores.
