v0.26.1

Fixed

• libherokubuildpack:
  • Fixed log_header, log_error and log_warning to correctly reset the ANSI colour styles at the end of each line. (#890)

v0.26.0

Changed

• libherokubuildpack:
  • Removed buildpack_output module. This functionality from (#721) was experimental. The API was not stable and it is being removed. A similar API is available at bullet_stream. (#852

  • Added inventory module. (#861)

v0.23.0

Changed

• libcnb-test:
  • pack build is now run with --trust-extra-buildpacks to force the builder to be trusted after upstream changes in Pack CLI. Pack CLI v0.35.1+ is now required to use libcnb-test. (#855)

v0.22.0

Added

• libcnb:
  • A new API for working with layers has been added. See the BuildContext::cached_layer and BuildContext::uncached_layer docs for examples of how to use this API. (#814)

Changed

• libcnb:
  • The Layer trait and related types and functions have been deprecated. Please migrate to the new API. (#814)
  • Errors related to layers have been restructured. While this is technically a breaking change, buildpacks usually don't have to be modified in practice. (#814)

Fixed

• libcnb-data:
  • The working directory for launch processes specifying a WorkingDirectory::Directory value is now respected. (#831)

v0.21.0

Added

• libcnb:
  • Made Target (the type of DetectContext::target and BuildContext::target) public. (#815)

Changed

• libcnb:
  • WriteLayerError changed to contain more specific error enums instead of generic ones. (#786)
• libcnb-data:

Added

• libcnb-data:
  • Reintroduced support for deserializing [[stacks]] in buildpack.toml.
