<ul dir="auto">
<li>Experimental support for free rotation of the main image (<code>Tools->Image Free Rotation...</code>)
<ul dir="auto">
<li>Polygon and paintbrush tools can be applied from oblique rotation angles</li>
</ul>
</li>
<li>Native support for 32 and 64 bit floating point images
<ul dir="auto">
<li>Previously, these images were represented internally as 16 bit integer, with rounding errors</li>
<li>NaN (not a number) values are supported, custom color can be assigned in the color map</li>
</ul>
</li>
<li>Performance improvements:
<ul dir="auto">
<li>Faster image load times made possible by efficient computatation of histogram and quantiles using the <strong><a href="https://github.com/SpirentOrion/digestible">tdigest</a></strong> data structure</li>
<li>Faster rendering of large 2D images</li>
</ul>
</li>
<li>Image IO Improvements:
<ul dir="auto">
<li>NRRD Volume Sequence Reading</li>
<li>4DCTA auto format detection now can detect wider range of images</li>
</ul>
</li>
<li>Improvements to label definitions file IO:
<ul dir="auto">
<li>A new submenu (<code>Segmentation->Label Definitions</code> includes recent items submenu)</li>
<li>Label definitions can be loaded by drag & drop</li>
</ul>
</li>
<li>New commands for reloading image layers (in context menus and layer editor):
<ul dir="auto">
<li>Main image and overlay can be reloaded from disk without closing the workspace</li>
<li>4D (3D+time) images can be reloaded as multi-component images and vice versa</li>
</ul>
</li>
<li>Added options to compose and invert transforms to the "open transform" dialog in the registration panel</li>
<li>Added a hotkey to switch between background & foreground labels</li>
<li>Added a hotkey to toggle continuous update of 3D rendering</li>
<li>More accurate UI text for loading/saving 3d/4d segmentations in 4d workspace</li>
<li>Multiple segmentation images can be loaded from the command line</li>
<li>Workspace tool <code>itksnap-wt</code> includes new commands for mesh layers</li>
</ul>

<ul dir="auto">
<li>Closing main image from layer context menu now will correctly prompt saving changes for overlay layers</li>
<li>Loading 3d segmentation into a 4d time point no longer prompts warning, if the time point does not have unsaved changes</li>
