 CHANGELOG
 =========
 
+0.10.9
+------
+
+- Extended-search mode is now enabled by default
+    - `--extended-exact` is deprecated and instead we have `--exact` for
+      orthogonally controlling "exactness" of search
+- Fixed not to display non-printable characters
+- Added `double-click` for `--bind` option
+- More robust handling of SIGWINCH
+
+0.10.8
+------
+
+- Fixed panic when trying to set colors after colors are disabled (#370)
+
+0.10.7
+------
+
+- Fixed unserialized interrupt handling during execute action which often
+  caused invalid memory access and crash
+- Changed `--tiebreak=length` (default) to use trimmed length when `--nth` is
+  used
+
 0.10.6
