+We've:

+- We replaced the `libsoup` server by `gevent.WSGIServer` to simplify Python 3 migration.

+The purpose is to prepare future:
+
+ - Migration to python3
+ - Increase performances of database
+ - Possibility to add an SQL backend (posgres json for example ?)
+ - Allow to handle several requests at once on ikaaro webserver
+ - Simplify build of javascript web applications with ikaaro
