1.001_004  Sun Aug  2 23:08:52 2009

    * Fixed mishandling of (??{....}) blocks

    * Various doc tweaks

    * Removed intermittent "uninitialized" warnings

    * Added warning when no main regex specified

    * Removed false error messages regarding explicitly use of built-in
      <ws> and <hk> rules

    * Fixed bug with negative lookaheads that incorporate subrule calls

    * Localized $/ during debugger interactions

      "internal" and "external" names for objrules and objtokens
      (thanks Casiano)
    
    * Fixed handling of (?#...) comments (thanks Casiano)

    * Added pure grammar definitions: <grammar: NAME>

    * Made @! contents unique (no more duplicates due to backtracking retries)

    * Made <MATCH=...> work in the top-level pattern of a grammar

    * Added set_context_width() to allow width of context string column 
      to be adjusted either permanently or within a scope. (Thanks Daniel)

      (thanks Andrew).

    * Fixed behaviour of ** repetitions wrt whitespace (thanks Andrew)

    * Documented more explicitly that start-pattern is supposed to act
      like a regular regex (or a token) wrt to whitespace



1.011  Sun Oct 10 18:57:10 2010

    * Added <!RULENAME> as alias for: (?! <.RULENAME> )

    * Added <?RULENAME> as alias for: (?= <.RULENAME> )

      to optimize error messages (thanks Nicolas)

    * Removed undocumented dependency of test suite on Class::Accessor
      (thanks Duff)

    * Tweaked caveats section to reflect improvements both in module

      regexes (regexes now reentrant)

    * Fixed problem with \N{NAMED CHARS} under 5.12 and later (thanks Tom!)

      debugging a grammar (mainly literals and backslashed
      metacharacters)

    * Fixed bug that prevented named subpattern captures from including 
      lookbehinds (e.g. <name=( (?<!foo) bar )> didn't work)


1.016  Sat Mar 10 07:01:30 2012

      (Thanks Peng)

    * Corrected docs for <debug: on>

      to <\_IDENT>


1.021  Mon Aug 20 13:55:34 2012

    * Made Latin-1 encoding of docs explicit


1.022  Tue Jan 22 18:39:16 2013

      (many more thanks Arseny!)




1.029  Tue Jun 25 15:44:35 2013

    * Doc patch (thanks Steven)

    * Added workarounds for some unfortunate changes in 5.18 behaviour
      (thanks Steven)

    * CRITICAL: Added warning regarding fundamental and intractable
      incompatibilities with Perl 5.18, and announcing that
      Regexp::Grammars is not supported under that version of Perl. :-(


1.030  Wed Jun 26 07:17:41 2013

    * Added essential-but-missing Skip_if_Perl_518 to the MANIFEST



1.031  Mon Aug 19 09:55:37 2013

    * Updated warning re 5.18 incompatibilities. Some progress has been
      made, but a complete solution is still at least a month away,
      possibly longer.

    * Added dependency on Lexical::Var under Perl 5.18 to overcome
      problem with magic pseudo-variables


1.032  Thu Aug 29 10:44:21 2013

    * Culled stray DB::single = 1 (thanks Robert!)


1.033  Sat Aug 31 13:10:57 2013

    * Listed dependency on Lexical::Var under Perl 5.18 to overcome
      problem with magic pseudo-variables (thanks Andreas!)



1.034  Wed Jun 11 06:50:04 2014

    * Reverted actual encoding to match nominated encoding (i.e. Latin-1)
      (thanks Olivier)

    * Fixed last bug preventing module from passing
      its own test suite under 5.20.

    * Gave up (for the present) on Perl 5.18 compatibility.

    * Noted limitations of passing %MATCH values as subrule args
      under 5.18+


1.035  Sat Jun 28 19:03:54 2014

    (All of the following with deepest thanks to Hugo...)

    * Removed no-longer-necessar Skip_if_Perl_518.pm from MANIFEST

    * Allowed rule declarations to be made anywhere
      (not just at the start of a line)

    * Fixed buggy edge-case for in-rule whitespace auto-matching
      at start of rule body (now works even if there is only a single
      whitespace between <rule: NAME> and first element of rule body)

    * Made R::G auto-/x any regex used under its suasion
      (solves formerly intractable problem of detecting a missing /x)

    * R::G now short-circuits any regex in its scope that does not
      contain any R::G constructs (and does not auto-/x them either)

    * Added line numbers to all warnings generated by the module

    * Added detection of "stray" quantifiers: unquoted quantifiers that
      don't actually quantify anything.

    * Added line-number annotations to the transformed regex as a
      last-gasp kind of assistance when confronted with the dreaded
      post-transformation "error marked with <-- HERE" message
