Hi,
In addition to a number of bug fixes, this combination of client and server v0.8.0 and v0.1.0 is the first set that should be able to run regularly without encountering any expected errors[1].

[1] In previous versions, compilation would result in a GET request that could take a longer time than the session would allow, leading to a timeout error. Repeated attempts to compile the same document would eventually succeed because the work that was done in the failed attempts was cached. Now, compilation is sent through a POST request that returns a pointer a status document, which can be checked to see when background compilation has finished.
