 ## 0.9 (current master/dev)
 
+#### 0.9.5
+
+- added dependency on PlotThemes
+- set_theme --> theme
+- remove Compat from REQUIRE
+- warning for DataFrames without StatPlots
+- closeall exported and implemented for gr/pyplot
+- fix DateTime recipe
+- reset theme with theme(:none)
+- fix link_axes! for nested subplots
+- fix plotly lims for log scale
+
+#### 0.9.4
+
+- optimizations surrounding Subplot.series_list
+- better Atom support, support plotlyjs
+- gr:
+    - gks_wstype defaults and gr_set_output
+    - heatmap uses GR.drawimage
+- histogram2d puts NaN for zeros
+- improved support of NaN in heatmaps
+- rebuilt spy recipes to output scatters with marker_z set
+- deprecate png support in plotly... point to plotlyjs
+- fixes:
+    - axis widen with lims set
+    - reset_extrema, setxyz
+    - bar plot widen
+    - better tick padding
+    - consistent tick rotation
+    - consistent aspect_ratio
+    - pyplot dpi
+    - plotly horizontal bars
+    - handle series attributes when combining subplots
+    - gr images transposed
+    - converted Date/DateTime to new type recipe approach for arrays
+- issues closed include: #505 #513 #479 #523 #526 #529
+
+#### 0.9.3
+
+- support pdf and eps in plotlyjs backend
+- allow curly after grid: `@layout [a b; grid(4,4){0.8h}]`
+- add_backend redesign
+
 #### 0.9.2
