Sourced from thiserror's releases.

2.0.12

• Prevent elidable_lifetime_names pedantic clippy lint in generated impl (#413)

2.0.11

• Add feature gate to tests that use std (#409, #410, thanks @​Maytha8)

2.0.10

• Support errors containing a generic type parameter's associated type in a field (#408)

2.0.9

• Work around missing_inline_in_public_items clippy restriction being triggered in macro-generated code (#404)

2.0.8

2.0.6

• Suppress deprecation warning on generated From impls (#396)

2.0.5

• Prevent deprecation warning on generated impl for deprecated type (#394)

2.0.4

• Eliminate needless_lifetimes clippy lint in generated From impls (#391, thanks @​matt-phylum)

2.0.3

• Improve error message when a format trait used in error message is not implemented by some field (#384)

2.0.2

• Fix hang on invalid input inside #[error(...)] attribute (#382)

2.0.1

• Support errors that contain a dynamically sized final field (#375)
• Improve inference of trait bounds for fields that are interpolated multiple times in an error message (#377)

2.0.0

Breaking changes

• Referencing keyword-named fields by a raw identifier like {r#type} inside a format string is no longer accepted; simply use the unraw name like {type} (#347)

  This aligns thiserror with the standard library's formatting macros, which gained support for implicit argument capture later than the release of this feature in thiserror 1.x.

  #[derive(Error, Debug)]
  #[error("... {type} ...")]  // Before: {r#type}
  pub struct Error {
      pub r#type: Type,
