Release Notes

harryfei/which-rs (which)

v7.0.2

Compare Source

• 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!

v7.0.1

Compare Source

• 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.

v7.0.0

Compare Source

• 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.
