The title really says it all but this has been a long time coming. Since the RenderContext changes in 0.6 there were some incompatibilities between the code in the tutorial and what actually worked. It wasn’t just an easy swap of method names – I spent some actual time today rewriting some big chunks of the first tutorial and adding an introduction to the RenderContext. The example app (The JSON Store) was also updated.
I’ve been thinking about part III and beyond as well, but thats for another day. I hope at least this fixes a lot of the confusion for people delving into Sammy for the first time.
