 OPENSEADRAGON CHANGELOG
 =======================
 
-3.0.1: (in progress)
+3.2.0: (in progress)
+
+* Improved the constraints that keep the image in the viewer, specifically when zoomed out a lot (#2160 @joedf)
+* You can now provide an element for the navigator (as an alternative to an ID) (#1303 @cameronbaney, #2166 #2175 @joedf)
+
+3.1.0:
 
 * Added subPixelRoundingForTransparency Viewer option to address seams that can appear in semi-transparent images (#2075 @TanukiSharp)

+* Added option to include POST data when loading files via Ajax (#2072 @Aiosa)
+* Exposed TiledImage's private functions for better maintainability (#2134 @Aiosa)
+* Tile cache keys are now generated by the tile source, so it's easier to override them as needed (#2138 @Aiosa)
+* Pinch to zoom now zooms around the center of the pinch, rather than the center of the viewer (#2158 @cavenel)
+* Added fallback and deprecation warning for Viewer.buttons (which got changed to buttonGroup in 3.0.0) (#2153 @devbyjonah)
 * Fixed an issue where turning off panVertical or panHorizontal would not affect the panning keyboard combos (#2069 @JachiOnuoha)
