 - [`#![test]` as an inner attribute is now considered unstable like other inner macro
   attributes, and reports an error by default through the `soft_unstable` lint.][79003]
 - [Overriding a `forbid` lint at the same level that it was set is now a hard error.][78864]
-- [Dropped support for all cloudabi targets.][78439]
 - [You can no longer intercept `panic!` calls by supplying your own macro.][78343] It's
   recommended to use the `#[panic_handler]` attribute to provide your own implementation.
 - [Semi-colons after item statements (e.g. `struct Foo {};`) now produce a warning.][78296]
