+### Changed
+

+    - `v0.1.3` to `v0.1.4`
+  - updated `actions/setup-go`
+    - `v2.1.0` to `v2.1.1`

+
+### Fixed
+
+- Documentation
+  - Add additional lead-in for `docs/ezproxy.md` to (hopefully) better explain
+    what EZproxy is
+  - Update main README to make majority of "EZproxy" references point to the
+    updated `docs/ezproxy.md` doc
+
+- Linting
+  - Use `filepath.Clean` for all `os.Open` calls
+    - even though this application is intended for use by sysadmins (who have
+      no cause to try and exploit the system), it's better to go ahead and
+      guard against potential exposure introduced by using externally-provided
+      (e.g., config file or flags) filenames by sanitizing the paths
+    - note: the `atc0005/go-ezproxy` `v0.1.4` release includes the same type
+      of changes
+  - errcheck: Explicitly check file close return values
+  - errcheck: Explicitly check writer flush return value
