-*To be released*
+## Version 2.5 - 'Craft'
+*Monday 13th April, 2015*
 [(view commits)](https://github.com/samaaron/sonic-pi/commits/v2.5.0)
 
+This release comes with support for
+[Minecraft: Pi Edition](http://pi.minecraft.net) installed on the
+Raspberry Pi. You can now create music with Minecraft visuals or even
+code up a synth score in Minecraft blocks and read and play the score
+from Sonic Pi! Another exciting aspect of this release is much improved
+editor functionality for navigating around and manipulating code via
+keyboard shortcuts. This means that live coding just got a lot more
+fun. The keyboard shortcuts are based on the standard shortcuts provided
+by [GNU Emacs](https://www.gnu.org/software/emacs/) - the oldest and
+most powerful text editor in use by wizard programmers today.

 ### Breaking Changes
 
 * `invert_wave` now defaults to 1 everywhere. I found I always inverted
    the wave every time I used a synth/fx where wave inversion was
    key. This seemed like such a better default I've broken compatibility
    for it. Apologies if this has affected you.
-* rename fx `ring` to `ring_mod` to reduce the potentiaon for confusion
+* The `flanger` FX now defaults the optional arg `stereo_invert_wave` to
+  1.
+* Renamed FX `ring` to `ring_mod` to reduce the potential for confusion
   with the `ring` datastructure.
-* `Tab` now indents current line rather than inserting a useless tab
-  character.
+* `Tab` now indents current line or selection rather than inserting a
+  useless tab character.
 
 ### New
 
 * Support for programming [Minecraft Pi Edition](http://pi.minecraft.net).
 * `sync` now accepts multiple cue ids and will sync on the first matching id.
+* New fn `pitch_ratio` for converting a midio note to a frequency
+  ratio. Useful for tuning samples.
 * New fn `line` for creating a line from start to finish with a specific
   number of slices.
 * New fn `spark` for displaying lists of numbers in a fancy text-graph
