Almost there: version 0.9.9 of RUR-PLE has been released

The title of this post pretty much says it all. I just need to write a few more lessons, read over once more all the existing lessons, do once more all the suggested exercises ... and, barring any surprises, I will be ready to release version 1.0 of RUR-PLE. Thus will end an adventure that started a little less than 2 years ago, as I decided to start a new hobby and learned about Python.
