 CHANGELOG
 =========
 
+0.17.5
+------
+
+- Bug fixes and improvements
+    - See https://github.com/junegunn/fzf/milestone/13?closed=1
+- Search query longer than the screen width is allowed (up to 300 chars)
+- Built with Go 1.11.1
+
+0.17.4
+------
+
+- Added `--layout` option with a new layout called `reverse-list`.
+    - `--layout=reverse` is a synonym for `--reverse`
+    - `--layout=default` is a synonym for `--no-reverse`
+- Preview window will be updated even when there is no match for the query
+  if any of the placeholder expressions (e.g. `{q}`, `{+}`) evaluates to
+  a non-empty string.
+- More keys for binding: `shift-{up,down}`, `alt-{up,down,left,right}`
+- fzf can now start even when `/dev/tty` is not available by making an
+  educated guess.
+- Updated the default command for Windows.
+- Fixes and improvements on bash/zsh completion
+- install and uninstall scripts now supports generating files under
+  `XDG_CONFIG_HOME` on `--xdg` flag.
+
+See https://github.com/junegunn/fzf/milestone/12?closed=1 for the full list of
+changes.
+
+0.17.3
+------
+- `$LINES` and `$COLUMNS` are exported to preview command so that the command
+  knows the exact size of the preview window.
+- Better error messages when the default command or `$FZF_DEFAULT_COMMAND`
+  fails.
+- Reverted #1061 to avoid having duplicate entries in the list when find
+  command detected a file system loop (#1120). The default command now
+  requires that find supports `-fstype` option.
+- fzf now distinguishes mouse left click and right click (#1130)
+    - Right click is now bound to `toggle` action by default
+    - `--bind` understands `left-click` and `right-click`
+- Added `replace-query` action (#1137)
+    - Replaces query string with the current selection
+- Added `accept-non-empty` action (#1162)
+    - Same as accept, except that it prevents fzf from exiting without any
+      selection
