# [1.0.0-beta.5](https://git.gitlab.arm.com/bazel/toolchain_utils/compare/v1.0.0-beta.4...v1.0.0-beta.5) (2024-04-24)

### Features

* support detecting triplet on MinGW ([ff280ae0](https://git.gitlab.arm.com/bazel/toolchain_utils/commit/ff280ae0b1aed1bfca9b667b07ddbb657e98cfc6))

# [1.0.0-beta.4](https://git.gitlab.arm.com/bazel/toolchain_utils/compare/v1.0.0-beta.3...v1.0.0-beta.4) (2024-03-25)

### Bug Fixes

* **export.symlink:** support multiple identical exports ([07a9c2c8](https://git.gitlab.arm.com/bazel/toolchain_utils/commit/07a9c2c832997967deaed6a8257789a03bf3450b))

A module can be in the module graph multiple times.

Each time the module is evaluated, a `export.symlink` tag will be created.

We can walk the graph to make sure that all exports are identical and
export once.

It is hermetic, `bazel_skylib` is not.

# [1.0.0-beta.3](https://git.gitlab.arm.com/bazel/toolchain_utils/compare/v1.0.0-beta.2...v1.0.0-beta.3) (2024-02-23)

Needed for APE binaries that support those systems.

# [1.0.0-beta.2](https://git.gitlab.arm.com/bazel/toolchain_utils/compare/v1.0.0-beta.1...v1.0.0-beta.2) (2024-02-21)

### Bug Fixes

* find POSIX shell with `/usr/bin/env` ([2294100e](https://git.gitlab.arm.com/bazel/toolchain_utils/commit/2294100e1efa4dee95bf61542cca3730bc618aa2))

When a repository is named `resolved-gcc`, we would expect the
basename of the resolved symlink to be `gcc` _not_ `resolved-gcc`.

The project was originally named `rules_toolchain`.

After bikeshedding for the Bazel Central Registry (BCR),
`toolchain_utils` was deemed a better name.

Always use the rule label as a directory and then put all files under that
directory.

Gracefully handles dot-files.

Be defensive on the kernel name
