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 #82 : Ellipsis literal (...) missing

  Demos
  =====
  
  Standard distribution
