-## 1.3.0
-
-* Expose a top-level `context` field that provides access to a `Context` object
-  for the current system.
-
-## 1.2.3
-
-* Don't cache path Context based on cwd, as cwd involves a system-call to
-  compute.
-
-## 1.2.2
-
-* Remove the documentation link from the pubspec so this is linked to
-  pub.dartlang.org by default.
-
-# 1.2.1
-
-* Many members on `Style` that provided access to patterns and functions used
-  internally for parsing paths have been deprecated.
-
-* Manually parse paths (rather than using RegExps to do so) for better
-  performance.
-
-# 1.2.0
-
-* Added `path.prettyUri`, which produces a human-readable representation of a
-  URI.
-
-# 1.1.0
-
-* `path.fromUri` now accepts strings as well as `Uri` objects.
