This release introduces a new formatting option, -wn (--weld-nested-containers). It also fixes some minor bugs which were were reported at CPAN.  

  - Added new flag -wn (--weld-nested-containers) which addresses these issues:
    RT #123749:	Problem with promises; 
    RT #119970: opening token stacking strange behavior;
    RT #81853: Can't stack block braces

    This option causes closely nested pairs of opening and closing containers
    to be "welded" together and essentially be formatted as a single unit,
    with just one level of indentation.

    Since this is a new flag it is set to be "off" by default but it has given 
    excellent results in testing. 

    EXAMPLE 1, multiple blocks, default formatting:
        do {
            {
                next if $x == $y;    # do something here
            }
        } until $x++ > $z;

    perltidy -wn
        do { {
            next if $x == $y;
        } } until $x++ > $z;

     EXAMPLE 2, three levels of wrapped function calls, default formatting:
            p(
                em(
                    conjug(
                        translate( param('verb') ), param('tense'),
                        param('person')
                    )
                )
            );

        # perltidy -wn
	    p( em( conjug(
		translate( param('verb') ),
		param('tense'), param('person')
	    ) ) );

        # EXAMPLE 3, chained method calls, default formatting:
        get('http://mojolicious.org')->then(
            sub {
                my $mojo = shift;
                say $mojo->res->code;
                return get('http://metacpan.org');
            }
        )->then(
            sub {
                my $cpan = shift;
                say $cpan->res->code;
            }
        )->catch(
            sub {
                my $err = shift;
                warn "Something went wrong: $err";
            }
        )->wait;

        # perltidy -wn
        get('http://mojolicious.org')->then( sub {
            my $mojo = shift;
            say $mojo->res->code;
            return get('http://metacpan.org');
        } )->then( sub {
            my $cpan = shift;
            say $cpan->res->code;
        } )->catch( sub {
            my $err = shift;
            warn "Something went wrong: $err";
        } )->wait;


  - Fixed RT #114359: Missparsing of "print $x ** 0.5;

  - Deactivated the --check-syntax flag for better security.  It will be
    ignored if set.  

  - Corrected minimum perl version from 5.004 to 5.008 based on perlver
    report.  The change is required for coding involving wide characters.

  - For certain severe errors, the source file will be copied directly to the
    output without formatting. These include ending in a quote, ending in a
    here doc, and encountering an unidentified character.
