Changes in Brython version 3.0.2
================================



New features
============

Implementation
==============
- destroy internal variables after comprehensions and generator expressions
  are executed
- add URLParameter function to browser module (by Billy Earney)
- new, much faster dict implementation (by James Hutchison and Billy Earney)
- dramatic performance improvement of str.format when format has 2 or more {}
  (by Mike "mrwwalmsley")
- add UUID function, replace some indent code with customized repeat functions
  (by Billy Earney)

Bug fixes
=========
- sys.stderr and sys.stdout can be reset (previously, only sys.stderr.write
  and sys.stdout.write could be)
- raise errors for assignment to None, True, False, debug
- fix bug in dir()
- string representation of functions and class methods are more compliant with
  that of CPython
- restore "throw" as a forbidden attribute (this broke Brython for some
  browsers on smartphones)

Issues
- issue #68 : possible silent overflow of larger ints (the bug is not fixed,
  but the results are more sensible)

- issue #83 : sys.version_info bug (by Billy Earney)

Brython site
============
- improved slideshow

- remove invalid "width" ace.js parameter (by Billy Earney)

Demos
=====

Standard distribution
=====================
- in browser.html and browser.svg, underscores in keywords are translated into
  hyphens : svg.rect(font_size=22) is correctly handled, with SVG attribute
  font-style set
- changes to random.py to make it load much faster. Makes the replacement
  module __random useless
- changes to re.py to make it load faster
