+# 1.5.3: Time delayed progress
+
+Rofi 1.5.3 is another bug-fix release in the 1.5 series. 
+
+There is one breaking change in the theme naming and there are a few small new features (tweaks) in this release.
+
+## Sidebar renamed to mode-switcher
+
+The selection buttons to select between the different modi was still called `sidebar` a remnant from the past.
+This has now been renamed to `mode-switcher`.
+
+## Icons in dmenu
+
+Just like in window,drun and script modi you can add icons to the list in dmenu mode.
+
+The syntax is similar to the script modi:
+
+```bash
+echo -en "Firefox\0icon\x1ffirefox\ngimp\0icon\x1fgimp" | rofi -dmenu -no-config -show-icons
+```
+

+
+
+The entries are separated by a `\n` newline (normal dmenu behaviour).
+The extra parameters can be added after a `\0` null character, the key and value are separated by a `\x2f` unit
+separator character.
+
+
+## Ellipsizing listview entries
+
+If you have very long entries in your view that get ellipsized (cut off at the end indicated by ...) you can now select,
+at runtime, where they are cut off (start, middle or end).
+
+You cycle through the options with the the `alt+.` keybinding.
+
+Start:
