All,
We have a new dev release today. It contains some fixes not included in the 0.5.1 release, but essentially it is featuring the new layout machinery. So, please, if you have time to test it and report any problem, it will be very appreciated, because the new layout merge was a big change, hence we will probably exposed to a amplified “bug surface” on master for some days, and you reports will let us diminish (quickly) that surface to a normal size 
As you probably know, these builds are being made available on binstar.org. If you are using Anaconda, you can install with conda by issuing:
conda install -c [http://conda.binstar.org/bokeh/channel/dev](http://conda.binstar.org/bokeh/channel/dev) bokeh
Alternatively you can install with pip:
pip install --pre -i [https://pypi.binstar.org/bokeh/channel/dev/simple](https://pypi.binstar.org/bokeh/channel/dev/simple) bokeh --extra-index-url [https://pypi.python.org/simple/](https://pypi.python.org/simple/)
Thanks to everyone!
Damián.
