## Changes from version version 2021 01 11 to version 2021 04 02

    - This release fixes several non-critical bugs which have been found since the last
    release.  An effort has been made to keep existing formatting unchanged.

    - Fixed issue git #57 regarding uninitialized warning flag.

    - Added experimental flag -lpxl=s requested in issue git #56 to provide some
    control over which containers get -lp indentation.

    - Fixed issue git #55 regarding lack of coordination of the --break-before-xxx
    flags and the --line-up-parens flag.

    - Fixed issue git #54 regarding irregular application of the --break-before-paren
    and similar --break-before-xxx flags, in which lists without commas were not 
    being formatted according to these flags.

    - Fixed issue git #53. A flag was added to turn off alignment of spaced function 
    parens.  If the --space-function-paren, -sfp flag is set, a side-effect is that the
    spaced function parens may get vertically aligned.  This can be undesirable,
    so a new parameter '--function-paren-vertical-alignment', or '-fpva', has been
    added to turn this vertical alignment off. The default is '-fpva', so that 
    existing formatting is not changed.  Use '-nfpva' to turn off unwanted
    vertical alignment.  To illustrate the possibilities:

        # perltidy [default]
        myfun( $aaa, $b, $cc );
        mylongfun( $a, $b, $c );

        # perltidy -sfp
        myfun     ( $aaa, $b, $cc );
        mylongfun ( $a, $b, $c );
    
        # perltidy -sfp -nfpva
        myfun ( $aaa, $b, $cc );
        mylongfun ( $a, $b, $c );

    - Fixed issue git #51, a closing qw bare paren was not being outdented when
    the -nodelete-old-newlines flag was set.

    - Fixed numerous edge cases involving unusual parameter combinations which
      could cause alternating output states.  Most scripts will not be
      changed by these fixes.
