 CHANGELOG
 =========

+0.41.1
+------
+- Fixed a bug where preview window is not updated when `--disabled` is set and
+  a reload is triggered by `change:reload` binding
+
+0.41.0
+------
+- Added color name `preview-border` and `preview-scrollbar`
+- Added new border style `block` which uses [block elements](https://en.wikipedia.org/wiki/Block_Elements)
+- `--scrollbar` can take two characters, one for the main window, the other
+  for the preview window
+- Putting it altogether:
+  ```sh

+  ```sh
+  # Reload the candidate list when there's no match
+  echo $RANDOM | fzf --bind 'zero:reload(echo $RANDOM)+clear-query' --height 3
+  ```
+- New actions
+    - Added `track` action which makes fzf track the current item when the
+      search result is updated. If the user manually moves the cursor, or the
+      item is not in the updated search result, tracking is automatically
+      disabled. Tracking is useful when you want to see the surrounding items
+      by deleting the query string.
+      ```sh
+      # Narrow down the list with a query, point to a command,
+      # and hit CTRL-T to see its surrounding commands.
+      export FZF_CTRL_R_OPTS="

Syphdias	37f258b1bf	Add key combinations for ctrl-delete and shift-delete (#3284 ) Currently there is not option to bind ctrl-delete and shift-delete. As suggested by issue #3240, shift-delete could be used to bind "delete entry from history" as it is a common way to do so in other applications, e.g. browsers. This, however, does only implement to use the key combination itself and does not assign a default action to any of them. This does enable to call one's all predefined actions. With the exec action this can expanded like the issue #3240 suggested. If desirable, the key combinations could later get a default behavior.

It is set to 'false' if the specified properties of the action is non-empty. * cf. toggle-preview takes the "current" preview window options and toggles the 'hidden' property.	2023-05-05 15:33:03 +09:00
