A new version of the asynchronous Psycopg wrapper for Tornado. Here is the list of changes for this release:

• Removed executemany from Momoko, because it can not be used in asynchronous mode.
• Added a wrapper class, Momoko, for Pool, BatchQuery and QueryChain.
• Added the QueryChain class for executing a chain of queries (and callables) in a certain order.
• Added the BatchQuery class for executing batches of queries at the same time.
• Improved Pool._clean_pool. It threw an IndexError when more than one connection needed to be closed.

And some documentation has been put online at momoko.61924.nl. Momoko can be downloaded from PyPi and Github.
