+#### Version 1.3.1 released on 25.04.15 ####
+
+  Bugfixes:
+    - Fixed bug that prevented automatic axis rescaling when some graphs/curves had only NaN data points
+    - Improved QCPItemBracket selection boundaries, especially bsCurly and bsCalligraphic
+    - Fixed bug of axis rect and colorscale background shifted downward by one logical pixel (visible in scaled png and pdf export)
+    - Replot upon mouse release is now only performed if a selection change has actually happened (improves responsivity on particularly complex plots)
+    - Fixed bug that allowed scatter-only graphs to be selected by clicking the non-existent line between scatters
+    - Fixed crash when trying to select a scatter-only QCPGraph whose only points in the visible key range are at identical key coordinates and vertically off-screen, with adaptive sampling enabled
+    - Fixed pdf export of QCPColorMap with enabled interpolation (didn't appear interpolated in pdf)
+    - Reduced QCPColorMap jitter of internal cell boundaries for small sized maps when viewed with high zoom, by applying oversampling factors dependant on map size
+    - Fixed bug of QCPColorMap::fill() not causing the buffered internal image map to be updated, and thus the change didn't become visible immediately
+    - Axis labels with size set in pixels (setPixelSize) instead of points now correctly calculate the exponent's font size if beautifully typeset powers are enabled
+    - Fixed QCPColorMap appearing at the wrong position for logarithmic axes and color map spanning larger ranges
+    
+  Other:
+    - Pdf export used to embed entire QCPColorMaps, potentially leading to large files. Now only the visible portion of the map is embedded in the pdf
+    - Many documentation fixes and extensions, style modernization
+    - Reduced documentation file size (and thus full package size) by automatically reducing image palettes during package build
+    - Fixed MSVC warning message (at warning level 4) due to temporary QLists in some foreach statements
