CHANGELOG.md

Changelog

1.1.0 - 2022-08-30

Fixed

• Unknown predicates now evaluate to false, matching Cargo's behavior.
  • As a result, Error::UnknownPredicate is no longer in use and has been deprecated.

1.0.2 - 2022-05-29

Changed

• Internal dependency updates.
• MSRV updated to Rust 1.56.

1.0.1 - 2022-02-07

Added

• Update badges in README.
• Add doc_cfg to the docs.rs build.

1.0.0 - 2022-02-06

No breaking changes in this release compared to version 0.9.

Changed

• Internal dependency version bump: cfg-expr updated to 0.10.0.

0.9.0 - 2021-10-01

Added

• Target triples can now be parsed directly into a PlatformSummary.

Changed

• PlatformSummary::new is now infallible.
• MSRV updated to Rust 1.53.

Fixed

• target-spec now uses cfg-expr's builtins by default, falling back to target-lexicon if cfg-expr isn't available.
  • This is because target-lexicon may not always produce results that match rustc's target JSONs.

0.8.0 - 2021-09-13

Added

• Triple represents a target triple, uniquely identified by a triple string.
• TargetExpression represents a target expression beginning with cfg(.

Changed

• target-spec now uses target-lexicon to parse triples, while continuing to use cfg-expr for expressions and evaluation.
  • Updated supported builtin targets to Rust 1.55.
  • target-spec is now more forward compatible, since new targets in future versions of Rust can be supported with non-breaking updates to target-lexicon.
• TargetSpec is now an enum with Triple and TargetExpression variants.
• Platform no longer has a lifetime parameter.
• Updated supported builtin targets to Rust 1.55.
• cfg-expr is now a private dependency again (target-lexicon is also a private dependency).
• MSRV updated to Rust 1.51.

0.7.0 - 2021-02-23

Changed

• Public dependency version bumps:
  • cfg-expr updated to 0.7.1.
  • proptest updated to version 1 and the corresponding feature renamed to proptest1.

0.6.1 - 2021-02-14

Changed

• cfg-expr version requirement relaxed: 0.6 through 0.7 are now supported. There are no API changes between the two versions.

0.6.0 - 2021-02-03

Added

• Platform now implements Hash + Eq + Ord.

Changed

• TargetFeatures and Platform::add_flags now accept Cow<'static, str>, simplifying lifetime management in many cases.
• cfg-expr updated to 0.6.0.

0.5.0 - 2020-12-02

Changed

• Updated cfg-expr dependency to 0.5.0.

0.4.1 - 2020-08-28

Fixed

• Fixed compilation on platforms without target features (#175).

0.4.0 - 2020-06-20

Added

• New, optional feature summaries to provide serialization and deserialization for Platform and TargetFeatures.
• Platform::is_custom returns true if the platform was created with the custom constructor.

Changed

• The error types have been unified into a single Error type.
• Platform::new and Platform::current now return errors instead of None.

0.3.0 - 2020-06-12

Added

• Platform::custom creates platforms that are unknown to rustc.
  • This is supported through cfg-expr, which is now a public dependency.
  • Custom platforms are often found in embedded Rust.

Changed

• In order to support custom platforms, Platform::triple now returns a &'a str instead of a &'static str.

0.2.4 - 2020-05-06

Added

• New feature proptest010 to generate random platforms for property testing.

0.2.3 - 2020-04-15

Fixed

• Better handling of unknown flags.
  • Unknown flags now evaluate to false instead of erroring out.
  • Added Platform::add_flags to allow setting flags that evaluate to true.

These changes were prompted by how cargo-web sets the cargo_web flag to true for cargo web build.

0.2.2

This was mistakenly published and was yanked.

0.2.1 - 2020-04-07

Changed

• Updated repository links.

0.2.0 - 2020-04-05

Added

• Added support for parsing specs and platforms separately from evaluating them, making error-less evaluation possible.
• Added support for target features, including situations when target features are unknown.

Changed

• Switched to cfg-expr as the backend for cfg() expressions.

0.1.0 - 2020-03-20

• Initial release.
