## Changes from version 20230309 to 20230701

    - No significant bugs have been found since the last release to CPAN.
      Several minor issues have been fixed, and some new parameters have been
      added, as follows:

    - Issue git #121. Added parameters -xbt, or --extended-block-tightness,
      and -xbtl=s, or --extended-block-tightness-list=s, to allow
      certain small code blocks to have internal spacing controlled by
      -bbt=n rather than -bt=n. The man pages have details.

    - Issue git #118. A warning will be issued if a duplicate format-skipping
      starting marker is seen within a format-skipping section. The same
      applies to duplicate code-skipping starting markers within code-skipping
      sections.

    - Issue git #116. A new flag --valign-if-unless, -viu, was added to
      allow postfix 'unless' terms to align with postfix 'if' terms.  The
      default remains not to do this.

    - Fixed git #115. In the two most recent CPAN releases, when the
      Perl::Tidy module was called with the source pointing to a file,
      but no destination specified, the output went to the standard
      output instead of to a file with extension ``.tdy``, as it should
      have.  This has been fixed.

    - Fixed git #110, add missing documentation for new options
      -cpb and -bfvt=n. These work in version 20230309 but the pod
      documentation was missing and has been added.

    - Fixed an undefined reference message when running with
      --dump-block-summary on a file without any subs or other
      selected block types.

    - Add parameter -ipc, or --ignore-perlcritic-comments.  Perltidy, by
      default, will look for side comments beginning with ``## no critic`` and
      ignore their lengths when making line break decisions, even if the user
      has not set ``-iscl``.  The reason is that an unwanted line break can
      make these special comments ineffective in controlling ``perlcritic``.
      The parameter -ipc can be set if, for some reason, this is not wanted.

    - Some minor issues with continuation indentation have been fixed.
      Most scripts will remain unchanged.  The main change is that block
      comments which occur just before a closing brace, bracket or paren
      now have an indentation which is independent of the existance of
      an optional comma or semicolon.  Previously, adding or deleting
      an optional trailing comma could cause their indentation to jump.
      Also, indentation of comments within ternary statements has been
      improved. For additonal details see:

    - This version was stress-tested for many cpu hours with random
      input parameters. No failures to converge, internal fault checks,
      undefined variable references or other irregularities were seen.

    - This version runs several percent faster than the previous release
      on large files.
