+# fish 2.3b2 (released May 5, 2016)
+
+## Significant changes
+
+- A new `fish_realpath` builtin and associated function to allow the use of `realpath` even on those platforms that don't ship an appropriate command (#2932).
+- Alt-# toggles the current command line between commented and uncommented states, making it easy to save a command in history without executing it.
+- The `fish_vi_mode` function is now deprecated in favour of `fish_vi_key_bindings`.
+
+## Other notable fixes and improvements
+
+- Fix the build on Cygwin (#2952) and RedHat Enterprise Linux/CentOS 5 (#2955).
+- Avoid confusing the terminal line driver with non-printing characters in `fish_title` (#2453).
+- Improved completions for busctl, git (#2585, #2879, #2984), and netctl.
