 # Changelog for https://github.com/mbarkhau/bumpver
 
+## BumpVer 2022.1115
+
+ - Fix: [use default date values][gh_i172].
+
+   When parsing the current version, if it doesn't specify anyt
+   date part, (such as is the case for e.g. SemVer), then use the
+   current date to populate default parts.
+
+   This enables updating YYYY patterns in copyright headers even
+   for projects that don't use a CalVer pattern.
+
+   Thank you [Benjamin Depardon (@bdepardo)][gh_bdepardo] for
+   finding and reporting this issue.
