This release is mostly focused on bug fixes, performance improvements and tweaks to Grunt's user interface
Performance: We found a way to significantly speed up Grunt's user interface, especially for Visual Grids
Bug fixes: We fixed several bugs that affected Grunt's stability
Charts
The axis will now reset to automatic when you change value types - e.g. from numbers to percent
We improved the algorithm that automatically calculates the distance between ticks on the chart y-axis
We improved the placement of chart categories so that you can now have empty categories
Bug fixes
We found and worked around a bug where you sometimes couldn't open the data editor for PowerPoint's native charts. We have reported this bug to Microsoft, but at least it will not fail when you have Grunt installed.
We fixed a rare bug where Grunt simply wouldn't load
