Today, we're announcing that Clippy will completely remove its plugin interface. Using the plugin interface has been deprecated for about one and a half year now (rust-lang/rust-clippy#2712). Since then, an unsilenceable warning has been emitted. Now that compiler plugins are officially deprecated (rust-lang/rust#64675), Clippy will remove its support for the plugin interface completely (rust-lang/rust-clippy#4714). This change will hit stable with version 1.41.0.
Does this post affect me?
Most likely, no. This post only affects you, if you're still using Clippy through its plugin interface. If you do so, you get the warning
warning: the clippy plugin is being deprecated, please use cargo clippy or rls with the clippy feature

How do I migrate from the plugin interface?

rustup component add clippy. Once installed, you can run
cargo clippy(for more usage instructions, see the Clippy
README). Note that Clippy is not included in every nightly, but you can check its availability on the rustup components history page.
