 CHANGELOG
 =========
 
+0.60.2
+------
+- Template for `--with-nth` and `--accept-nth` now supports `{n}` which evaluates to the zero-based ordinal index of the item
+- Fixed a regression that caused the last field in the "nth" expression to be trimmed when a regular expression delimiter is used
+    - Thanks to @phanen for the fix
+- Fixed 'jump' action when the pointer is an empty string
+
+0.60.1
+------
+- Bug fixes and minor improvements
+    - Built-in walker now prints directory entries with a trailing slash
+    - Fixed a bug causing unexpected behavior with [fzf-tab](https://github.com/Aloxaf/fzf-tab). Please upgrade if you use it.
+- Thanks to @alexeisersun, @bitraid, @Lompik, and @fsc0 for the contributions
