Ocsigen

A simpler and safer way
to write Web applications!

Each request now has a polymorphic data table (called request cache), where you can store the data you want to keep during the whole page generation. Use Eliom_sessions.get_request_cache ~sp to get it. And see the interface of module Polytables to understand how it works.
Actions now return (). If you want to send information to subsequent services, use the request cache.
The order of parameters of user type form widgets has changed.
Suffixes in services have been reimplemented, making them a lot more powerful, but with very small incompatibilities. Be careful to tests your services with suffixes.
The textarea widget now take a string (was pcdata).
The <timeout> option in configuration file disappeared (now: <volatiletimeout>).

The findlib-package attribute of <extension> and <library> elements doesn't accept the prefix ocsigen_ext anymore, use ocsigen.ext.
