1.52.1 is a patch release. Key changes include:

• This release disables incremental compilation, unless the user has explicitly opted in via the newly added RUSTC_FORCE_INCREMENTAL=1 environment variable.;
• This is due to the widespread, and frequently occurring, breakage encountered by Rust users due to newly enabled incremental verification in 1.52.0..

1.52.0 is a minor release. Key changes include:

• Added the unsafe_op_in_unsafe_fn lint, which checks whether the unsafe code in an unsafe fn is wrapped in a unsafe block. This lint is allowed by default, and …;
• You can now cast mutable references to arrays to a pointer of the same type as the element..

1.51.0 is a minor release. Key changes include:

• You can now parameterize items such as functions, traits, and structs by constant values in addition to by types and lifetimes. Also known as "const generics" …;
• Added the -Csplit-debuginfo codegen option for macOS platforms. This option controls whether debug information is split across multiple files or packed into a ….

1.50.0 is a minor release. Key changes include:

• You can now use const values for x in [x; N] array expressions. This has been technically possible since 1.38.0…;
• Assignments to ManuallyDrop union fields are now considered safe..
