+# 1.6.0 (2016-04-18)
+
+- Issue #26: Added Init method to initialize a repo at the local location
+  (thanks tony).
+- Issue #19: Added method to retrieve tags for a commit.
+- Issue #24: Reworked errors returned from common methods. Now differing
+  VCS implementations return the same errors. The original VCS specific error
+  is available on the error. See the docs for more details.
+- Issue #25: Export the function RunFromDir which runs VCS commands from the
+  root of the local directory. This is useful for those that want to build and
+  extend on top of the vcs package (thanks tony).

+  accessible.
