 CHANGELOG
 =========
 
+0.15.7
+------
+- Fixed panic when color is disabled and header lines contain ANSI colors
+
+0.15.6
+------
+- Windows binaries! (@kelleyma49)
+- Fixed the bug where header lines are cleared when preview window is toggled
+- Fixed not to display ^N and ^O on screen
+- Fixed cursor keys (or any key sequence that starts with ESC) on WSL by
+  making fzf wait for additional keystrokes after ESC for up to 100ms
+
+0.15.5
+------
+- Setting foreground color will no longer set background color to black
+    - e.g. `fzf --color fg:153`
+- `--tiebreak=end` will consider relative position instead of absolute distance
+- Updated `fzf#wrap` function to respect `g:fzf_colors`
+
 0.15.4
 ------
 - Added support for range expression in preview and execute action
