Changes in version 0.5.0 (2026-04-18)                  

Fixed

  - The Makevars.in / Makevars.win.in templates installed by
    use_extendr() now pass identical RUSTFLAGS, @PANIC_EXPORTS@ (Unix),
    and @PROFILE@ to both the cargo build --lib and cargo run --bin
    document invocations. Previously the second invocation ran with
    neither, which gave it a different fingerprint and caused cargo to
    rebuild every dependency from scratch on package install.
    (extendr/extendr#1087)

Added

  - use_extendr() now generates cleanup and cleanup.win. (#473)
  - Refactor of rust_source() and rust_function() (#478)
      - Adds opts = extendr_options() to simplify rust_source() API with
        ... to maintain backwards compatibility
      - Adds rlang standalone type checks to rust_source() and
        rust_function()
      - Replaces internal invoke_cargo() with run_cargo() in
        rust_source()
      - Simplifies handling of macro options in
        rust_function(extendr_fn_options = list())
      - Unknown macro options in dev and release now throw errors
        instead of warnings
  - vendor_pkgs() now has a clean argument to remove the src/rust/vendor
    directory after creating the vendor.tar.xz file. (#479)
  - Added update_scaffold() to overwrite scaffolding, making it easier
    to update packages to track developments in extendr and rextendr.
    (#493)
  - write_license_note() is now marked as experimental. The authors
    field in Cargo metadata is deprecated upstream
    (https://github.com/rust-lang/cargo/issues/16458) and crates may
    stop populating it, leading to incomplete author information.

Deprecated

  - vendor_pkgs() has been renamed to vendor_crates() to better reflect
    that it vendors Rust crates. vendor_pkgs() is soft-deprecated and
    will be removed in a future release.
  - Complete overhaul of wrapper-generation. (#491)
      - rextendr::document() is now a thin wrapper around
        devtools::document() and is soft deprecated. Packages created
        with use_extendr() no longer require it. It is retained for
        backwards compatibility.
      - register_extendr() is no longer called in rextendr::document()
        and is soft deprecated. The function itself is no-op and now
        returns a lifecycle warning.
      - Deprecating register_extendr() effectively nullifies the PkgGen
        CI tests, so those have been removed.

Breaking

  - Complete overhaul of wrapper-generation. (#491)
      - use_extendr() now generates src/rust/document.rs and adds a
        [[bin]] target to Cargo.toml with crate-type = ["rlib",
        "staticlib"].
      - rust_eval() now returns extendr_api::error::Result<Robj>.
      - The header in R/extendr-wrappers.R has also been updated to
        reflect these changes, which required a concurrent PR to extendr
        (extendr/extendr#1048).
      - CI now uses the development version of extendr-api on GitHub.
      - Snapshot and other tests now reflect these changes.
      - Substantial updates to Roxygen documentation.

Fixed

  - Makevars(.win) now uses the vendor/, if it exists, before unzipping
    the tarball. (#479)
  - entrypoint.c now registers extendr's panic handler. (#499)

Changed

  - callr has been removed as a dependency.

                 Changes in version 0.4.2 (2025-08-26)                  

  - Sets the extendr-api version to the latest stable version instead of
    "*" when creating a new package. This is fetched from
    https://crates.io/api/v1/crates/extendr-api and will fall back to
    "*" if not available https://github.com/extendr/rextendr/pull/467
  - Adds xz to SystemRequirements to ensure extendr based packages build
    on Posit Package Manager
    https://github.com/extendr/rextendr/pull/467
  - Sets the release profile to use lto=true and codegen-units=1 to
    ensure compatible builds with WebR as well as reduce the overall
    compiled package size https://github.com/extendr/rextendr/pull/465.
  - Fixes compatibility with WebR by adding
    CARGO_PROFILE_DEV_PANIC="abort" CARGO_PROFILE_RELEASE_PANIC="abort"
    when targeting wasm32-unknown-emsacripten target
    https://github.com/extendr/rextendr/pull/461

                 Changes in version 0.4.1 (2025-06-19)                  

  - Fix tests executed on CRAN (#449)

  - Added use_vscode() and its alias use_positron() to create
    .vscode/settings.json, enhancing the rextendr experience in
    VSCode/Positron. Additionally, use_extendr() now automatically calls
    use_vscode() when VSCode or Positron is detected as the IDE (#441).

                 Changes in version 0.4.0 (2025-05-02)                  

  - Adds WebR support out of the box for all extendr packages.
      - Note that not all Rust crates are wasm compatible. This change
        only enables the package to build in the
        wasm32-unknown-emscripten target. It does not guarantee all
        dependencies will compile.
  - Addresses new CRAN check in R 4.5+ adding warning for _abort usage
  - use_extendr_badge() has been added to add an extendr-specific badge
    to a README.Rmd via usethis::use_badge()
    https://github.com/extendr/rextendr/pull/417
  - Removes Makevars.ucrt as R versions < 4.1 are not supported by
    extendr https://github.com/extendr/rextendr/pull/414
  - purrr has been replaced with R/standalone-purrr.R removing purrr
    from Imports https://github.com/extendr/rextendr/pull/408
  - document() will no longer try to save all open files using
    rstudioapi https://github.com/extendr/rextendr/issues/404
    https://github.com/extendr/rextendr/issues/407
  - use_cran_default() has been removed as the default package template
    is CRAN compatible https://github.com/extendr/rextendr/pull/394
  - use_extendr() now creates tools/msrv.R, configure and configure.win.
    These have been moved out of use_cran_defaults()
    https://github.com/extendr/rextendr/pull/393
  - Makevars now prints linked static libraries at compile time by
    adding --print=native-static-libs to RUSTFLAGS
    https://github.com/extendr/rextendr/pull/393
  - use_extendr() sets the DESCRIPTION's SystemRequirements field
    according to CRAN policy to Cargo (Rust's package manager), rustc
    (#329)
  - Introduces new functions use_cran_defaults() and vendor_pkgs() to
    ease the publication of extendr-powered packages on CRAN. See the
    new article CRAN compliant extendr packages on how to use these
    (#320).
  - rust_sitrep() now better communicates the status of the Rust
    toolchain and available targets. It also guides the user through
    necessary installation steps to fix Rust setup (#318).
  - use_extendr() and document() now set the SystemRequirements field of
    the DESCRIPTION file to Cargo (rustc package manager) if the field
    is empty (#298).
  - use_extendr() gets a new ability to overwrite existing rextendr
    templates (#292).
  - use_extendr() sets publish = false in the [package] section of the
    Cargo.toml (#297).
  - use_extendr() correctly handles calls with path not equal to "."
    (current folder), or when there is no active {usethis} project
    (#323).
  - Fixes an issue in pre-defined set of known features: added either
    (#338)
  - create_extendr_package() allows user to create project directory
    using RStudio's Project Command. (#321)
  - Support RTOOLS44 (#347)
  - Removed use_try_from as an option in rust_function, and added
    use_rng (#354)
  - Added use_crate() function to make adding dependencies to Cargo.toml
    easier within R, similar to usethis::use_package() (#361)
  - Fixed an issue in rust_source() family of functions that prevented
    usage of r# escape sequences in Rust function names (#374)
  - use_cran_defaults() now checks the SystemRequirements field in the
    DESCRIPTION file for cargo and rustc. It will display installation
    instructions if either is missing or provide the minimum required
    version if the installed version is outdated.
  - Added use_msrv() to aid in specifying the minimum supported rust
    version (MSRV) for an R package
  - Added read_cargo_metadata() to retrieve Cargo metadata for packages
    and workspaces. (#389)
  - rustup_sitrep() now checks if a default toolchain has been set.
    https://github.com/extendr/rextendr/pull/416
  - Minimum R version is set to 4.1 (#435)
  - {tibble} is no longer a dependency (#435)

  - Ilia Kosenkov is now the official maintainer.

  - Josiah Parry is now a contributor.

  - Support Rtools43 (#231).

  - rextendr has migrated to the use of cli for raising errors and
    warnings.

  - Developer note: new helper function local_quiet_cli() introduced in
    R/utils.R to simplify silencing cli output.

New features

  - A new function rust_sitrep() that prints out a short report on the
    currently installed Rust toolchain (#274).

  - A new function write_license_note() to generate LICENSE.note file
    from Cargo.toml (#271).

  - extendr_fn_options parameter of rust_source() controls what type of
    options are emitted to #[extendr()] attribute (#252).

  - use_dev_extendr flag makes rust_source() family of functions compile
    code using development version of extendr. Development configuration
    is stored as an option named rextendr.extendr_dev_deps (#251).

  - features parameter of rust_source() now correctly enables features
    in extendr-api and references required crates. features not
    available in release version of extendr raises a warning (#249).

  - A <pkg_name>-win.def file containing DLL exports is created by
    rextendr::use_extendr(). It is used during linking phase on Windows
