- update to 2.4.2:

Browse Source 
- Updated the shorthand notation that has been added for repetition
    expressions: expr[min, max], with '...' valid as a min or max value
  - The defaults on all the `__diag__` switches have been set to False,
    to avoid getting alarming warnings. To use these diagnostics, set
    them to True after importing pyparsing.
  - Fixed bug introduced by the use of __getitem__ for repetition,
    overlooking Python's legacy implementation of iteration
    by sequentially calling __getitem__ with increasing numbers until
    getting an IndexError. Found during investigation of problem
    reported by murlock, merci!
  - Changed [...] to emit ZeroOrMore instead of OneOrMore.
  - Removed code that treats ParserElements like iterables.
  - Change all __diag__ switches to False.
- update to 2.4.1.1:
  - API change adding support for `expr[...]` - the original
    code in 2.4.1 incorrectly implemented this as OneOrMore.
    Code using this feature under this relase should explicitly
    use `expr[0, ...]` for ZeroOrMore and `expr[1, ...]` for
    OneOrMore. In 2.4.2 you will be able to write `expr[...]`
    equivalent to `ZeroOrMore(expr)`.
  - Bug if composing And, Or, MatchFirst, or Each expressions
    using an expression. This only affects code which uses
    explicit expression construction using the And, Or, etc.
    classes instead of using overloaded operators '+', '^', and
    so on. If constructing an And using a single expression,
    you may get an error that "cannot multiply ParserElement by
    0 or (0, 0)" or a Python `IndexError`.
  - Some newly-added `__diag__` switches are enabled by default,
    which may give rise to noisy user warnings for existing parsers.
