Cairo release notes ➡️

Welcome to the release notes for Scarb v2.9.1!
This release includes several new developments and fixes.

  • Interface changes

    • Allow ignoring Cairo version checks - Version requirements defined in cairo-version fields in package manifests can be ignored with new --ignore-cairo-version flag.
    • Add redeposit gas flag - Compiler config now includes add_redeposit_gas flag.

  • Compilation model changes

    • Component dependencies in Scarb metadata - Scarb metadata includes information about dependencies of each component in a compilation unit.
    • Integration tests features - Integration tests should be compiled with the same feature set, as the main package.
    • Disallow imports by target name in integration tests - Integration tests cannot rely on test target name to reference self in imports and should use use crate::(...) instead.

  • Warnings and diagnostics

    • Edition unset warnings - Warnings are emitted for all loaded packages with no edition set in package manifest.
    • Warnings from dependencies silenced when building tests - Warnings originating in package dependencies are silenced when building package tests.

  • Bug fixes

    • Fix registry client cache file - Simultaneous access to a registry client cache file could result in interrupted downloads due to a race condition, fixed with advisory lock.

  • Procedural macros changes

    • Packaging procedural macros - Packages implementing procedural macros (with [cairo-plugin] target) can now be packaged with scarb package and published with scarb publish.
    • Inline procedural macro arguments - Inline procedural macros defined with Scarb do not get function name as part of the arguments token stream - only the associated arguments list (with delimiters).
    • Fix check command for procedural macros - Scarb check now properly builds all procedural macros required by the package.

  • New Scarb doc features

    • Reexported modules documentation support - Documentation generated with scarb doc now includes docs of modules reexported from the package.
    • Cross item linkeage support - Generated project documentation now resolves item references with [some::cairo::path] syntax, as clickable links.
    • Struct members signature - Documentation of structs, generated with scarb doc now includes struct's members signatures.
    • Diagnostics when generating documentation - If generating documentation of a package fails due to invalid Cairo code, Scarb should exit gracefully while showing compiler diagnostics instead of panicking.
    • Hiding docs of impls of hidden traits - Impls of traits hidden with doc(hidden) attributes are skipped when generating documentation with scarb doc.
    • Corelib documentation on Scarb website - Cairo core library documentation is now automatically published on Scarb documentation website with every release.
