v0.11.1

Fixed

• All crates now properly include the LICENSE file. (#506)
• Fix libcnb readme file metadata which prevented vendoring libcnb via cargo vendor. (#506)

Changed

• Improve the libherokubuildpack root module rustdocs. (#503)

v0.11.0

Changed

• Bump Minimum Supported Rust Version (MSRV) to 1.64. (#500)
• Bump minimum external dependency versions. (#502)

Added

• Add new crate libherokubuildpack with common code that can be useful when implementing buildpacks with libcnb. Originally hosted in a separate, private, repository. Code from libherokubuildpack might eventually find its way into libcnb.rs proper. At this point, consider it an incubator. (#495)

v0.10.0

Highlight of this release is the bump to Buildpack API 0.8 which brings support for SBOM to libcnb.rs. This is also the first release where all libcnb.rs crates are released at the same time and with the same version number. See the changelog below for other changes.

Changed

• libcnb.rs now targets Buildpack API 0.8. Buildpacks need to upgrade the api key to 0.8 in their buildpack.toml. (#489)
• In accordance to the CNB specification >=0.7, BuildpackId no longer permits sbom as a buildpack id. (#489)
• Replace builder style functions from Launch with a dedicated LaunchBuilder to be more consistent with other builders in the library. Additionally, all fields of Launch can now be modified via the builder pattern. (#487)
• Rename paths field in launch::Slice to path_globs and add docs to make it clearer that these strings are Go standard library globs. (#487)
• Add explicit DeleteLayerError to provide more context when debugging layer handling problems. (#488)

Fixed

• Fix BuildpackApi to use u64 instead of u32 for major and minor version parts. (#489)
• Fix permission issues during layer handling when the layer contains read-only directories. (#488)

Added

• Add BuildResultBuilder::build_sbom, BuildResultBuilder::launch_sbom and LayerResultBuilder::sbom to enable buildpack authors to attach SBOM data for layers and launch. (#489)
• Add sbom::SbomFormat, describing supported SBOM formats. (#489)
• Add Buildpack::sbom_formats field. (#489)
• Add support for setting a working directory for launch processes. (#489)
• Add TestContext::download_sbom_files to allow testing of SBOM logic. (#489)

Removed

• Remove support for legacy BOM. Remove Launch::bom, Build::bom, bom::Bom, bom::Entry. (#489)

libcnb-test v0.6.0

• Overhaul the crate README/docs, to improve the learning/onboarding UX. (#478)
• Rename TestRunner::run_test to TestRunner::build, TestConfig to BuildConfig and TestContext::run_test to TestContext::rebuild. (#470)
• Add TestContext::start_container, TestContext::run_shell_command and ContainerConfig. (#469)
• Remove TestContext::prepare_container and PrepareContainerContext. To start a container use TestContext::start_container combined with ContainerConfig (or else the convenience function TestContext::run_shell_command) instead. (#469)
• Fix missing logs when using ContainerContext::logs_now. (#471)

libcnb v0.9.0

• Use the crate's README.md as the root module's rustdocs, so that all of the crate's documentation can be seen in one place on docs.rs. (#460)
• Increase minimum supported Rust version from 1.58 to 1.59. (#445)
• Update libcnb-data (which provides the types in the data module) from 0.7.0 to 0.8.0 - see the libcnb-data changelog. (#465)
• Update libcnb-proc-macros from 0.2.2 to 0.3.0 - see the libcnb-proc-macros changelog. (#465)

libcnb-test v0.5.0

• Add an assert_empty! macro, for improved UX over using assert! with str::is_empty. (#451)
• Add TestConfig::cargo_profile and CargoProfile to support compilation of buildpacks in release mode. (#456)
• Improve the error message shown when Pack CLI is not installed. (#455)
• Check that TestConfig::app_dir is a valid directory before applying TestConfig::app_dir_preprocessor or invoking Pack, so that a clearer error message can be displayed. (#452)
• PrepareContainerContext::start_with_shell_command and ContainerContext::shell_exec now use bash instead of /bin/sh. (#464)
• Use the crate's README.md as the root module's rustdocs, so that all of the crate's documentation can be seen in one place on docs.rs. (#460)
• Add rustdocs with code examples for all public APIs. (#441)
• Fix rustdocs for LogOutput. (#440)
• Increase minimum supported Rust version from 1.58 to 1.59. (#445)
• Update libcnb-package from 0.1.2 to 0.2.0. Of note, buildpack binaries are now stripped when packaging to reduce buildpack size, which also speeds up integration tests. See the libcnb-package changelog. (#465)

libcnb-proc-macros v0.3.0

• Disable fancy-regex default features (such as unused unicode support) to reduce buildpack binary size. (#439)
• Fix verify_regex's error handling when the regex could not be compiled. (#438)
• Add a crate README.md and use it as the root module's rustdocs, so that all of the crate's documentation can be seen in one place on docs.rs. (#458 and #460)
• Increase minimum supported Rust version from 1.58 to 1.59. (#445)

libcnb-package v0.2.0

• Strip buildpack binaries when packaging, to reduce buildpack size. This not only reduces the size of production builder images, but also speeds up workflows that involve non-release builds (such as integration tests). (#445)
• The type of the cargo_env argument to build::build_buildpack_binaries and build::build_binary has changed. (#445)
• Use the crate's README.md as the root module's rustdocs, so that all of the crate's documentation can be seen in one place on docs.rs. (#460)
• Increase minimum supported Rust version from 1.58 to 1.59. (#445)
• Update libcnb-data from 0.7.0 to 0.8.0 - see the libcnb-data changelog. (#465)

libcnb-data v0.8.0

• Disable fancy-regex default features (such as unused unicode support) to reduce buildpack binary size. (#439)
• Add a crate README.md and use it as the root module's rustdocs, so that all of the crate's documentation can be seen in one place on docs.rs. (#458 and #460)
• Increase minimum supported Rust version from 1.58 to 1.59. (#445)
• Update libcnb-proc-macros from 0.2.2 to 0.3.0 - see the libcnb-proc-macros changelog. (#465)

libcnb-cargo v0.5.0

• Fix the packaged buildpack size reported by cargo libcnb package. (#442)
• Reduce number of dependencies to improve installation time. (#442 and #443)
• Use the crate's README.md as the root module's rustdocs, so that all of the crate's documentation can be seen in one place on docs.rs. (#460)
• Increase minimum supported Rust version from 1.58 to 1.59. (#445)
• Update libcnb-package from 0.1.2 to 0.2.0. Of note, buildpack binaries are now stripped when packaging to reduce buildpack size. See the libcnb-package changelog. (#465)
