+##Non working examples
+
+- http://localhost:8888/web/examples/filter-stacks.html 
+ (fading is peculiar)
+- http://localhost:8888/web/zoom/restrict-panning.html
+  Need to increase height of range chart - currently height of
+  brushable area is zero. New implementation needs it be more than zero.
+- http://localhost:8888/web/  
+  Range brushing inconsistent with previous version
+  If the range chart is brushed first it works correctly
+  If the Focus chart is zoomed first, brushing range chart fails.
+
+
+##Issues to be fixed
+
+- Peculiar fading in filter-stacks.html (Medium)
+
+
+##Before release
+
+- All High priority issues
+- Possibly Medium priority issues
+- Prepare upgrade guide (Initial version ready)
+
+
+### Next set of pull requests
+
+- Cleanup of zoom behavior. Testing of restrict panning etc.
+- dc.event.trigger
+- exit/enter/update sequence
+- Additional test cases for dc.util.add and dc.util.subtract
+- One for each new chart type - original PRs from community
+- Consider removing transitions for zooming and brushing
+- d3 stack to D3v4
+- Changing .tension call in lineChart

+# dc v3 Upgrade Guide
+
+The dc has undergone significant internal changes while moving to v3.
+Effort has been made to keep the API as close as possible.
+
+d3 team has released version 4 which is not backward compatible with
+their version 3. dc relies very heavily on d3. It is quite likely that
+your code uses bits of d3.
+
+Outline of the upgrade process:
+
+- First of all update all d3 functions calls in your code. Most of these
+  would start with d3. Check https://github.com/d3/d3/blob/master/CHANGES.md
+  for new function name corresponding to old functions.
+- dc.lineChart .interpolate earlier took string parameter, these will get
+  replaced by specialized curve functions. For example 'step-before'
+  changes to `d3.curveStepBefore` and 'cardinal' to `d3.curveCardinal`.
+  See https://github.com/d3/d3/blob/master/CHANGES.md#shapes-d3-shape
+  for equivalent function calls.
+- For dc.geoChoroplethChart earlier `d3.geoAlbersUsa()` was the default
+  for .projection. If you are plotting US states please call 
+  `.projection(d3.geoAlbersUsa())` explicitly on your chart.
