Changelog

Sourced from which's changelog.

7.0.2

• Don't return paths containing the single dot . reference to the current directory, even if the original request was given in terms of the current directory. Thanks @​jakobhellermann for this contribution!

7.0.1

• Get user home directory from env_home instead of home. Thanks @​micolous for this contribution!
• If home directory is unavailable, do not expand the tilde to an empty string. Leave it as is.

7.0.0

• Add support to WhichConfig for a user provided closure that will be called whenever a nonfatal error occurs. This technically breaks a few APIs due to the need to add more generics and lifetimes. Most code will compile without changes.

6.0.3

• Enhance tracing feature with some debug level logs for higher level logic.

6.0.2

• Add tracing feature which outputs debugging information to the tracing ecosystem.

6.0.1

• Remove dependency on once_cell for Windows users, replace with std::sync::OnceLock.

6.0.0

• MSRV is now 1.70
• Upgraded all dependencies to latest version

5.0.0

• Remove several unused error messages
• Windows executables can now be found even if they don't have a '.exe' extension.
• Add new error message, Error::CannotGetCurrentDirAndPathListEmpty

4.4.2

• Remove dependency on dirs crate due to MPL licensing in its tree. Use home crate instead. (@​Xaeroxe)
