 ### Changed
 - If a "sharing violation" error is encountered while opening a connection to a
   YubiKey, and `scdaemon` is running (which can hold exclusive access to a
   YubiKey indefinitely), `age-plugin-yubikey` now attempts to stop `scdaemon` by
   interrupting it (or killing it on Windows), and then tries again to open the
   connection.
+- Several error messages were enhanced with guidance on how to resolve their
+  respective issue.
 
 ## [0.3.0] - 2022-05-02
