Changes in Brython version 20131201-221358
==========================================

Backward incompatibilities
==========================
- the names "doc", "win", "alert", "prompt", "confirm" are no more built-in, they must be imported from the module "browser"
- likewise, "JSObject" and "JSConstructor" must be imported from the module "javascript"
- the modules ajax, html, local_storage, markdown, pydom, indexed_db, svg must be imported from the package "browser"
- functions set_timeout, clear_timeout, set_interval and clear_interval are now defined in the module browser.timer, instead of the module time

Site layout
===========
- the interactive console is accessed from the link "console", the online editor from the link "editor"

Keywords
========
- "raise A from B" not really supported, but doesn't raise a SyntaxError

Built-in functions
==================
- support of super(), issubclass(), __import__()
- complex() is not supported, but is defined so as not to raise a ReferenceError
- improved version of callable()
- improve enumerate() : argument start, return value of __next__()
- improve print() : support keyword argument sep

Built-in classes
================

- fix __len__ and __repr__ for bytes objects

Standard distribution
=====================
