Changes in version 0.3.0                        

New features

  - Macros may now reference other macros (recursive macros). Macro
    values are fully expanded at parse time; circular references produce
    an error.

  - We now export (and document their arguments) the following movetext
    parsers:
    
      - piecepack_parser()

Bug fixes and minor improvements

  - Fixes bug in process_exclamation_move() (e.g. !PieceId moves).
  - Eliminated use of deprecated ppdf functions.

                        Changes in version 0.2.1                        

Deprecated features

  - Custom movetext parsers should now be of the form name_parser()
    instead of parser_name().

New features

  - We now export (and document their arguments) the following movetext
    parsers:
    
      - alquerque_parser()
      - default_parser()
      - checker_parser()
      - chess_parser()
      - domino_parser()
      - go_parser()
      - marble_parser()
      - morris_parser()
      - tarot_parser()

Bug fixes and minor improvements

  - The following tweaks to PPN:
    
      - If a PieceSpec is missing Piece and is a colored suit and it's
        side is not l, r, or x then it is now assumed to be a "bit"
        (instead of a "tile").
      - If a "marbles" "bit" is missing its rank assume that its rank is
        9L (i.e. 1" marble when visualized by {piecepackr}).
      - The Unicode symbols for checker kings (i.e. ⛁ and ⛃) are now
        interpreted as checker bits face up (instead as not being
        interpreted as checker pieces at all).
      - Now handles the Unicode symbols for rotated chess pieces.
      - Now handles the Unicode symbols for "neutral" chess pieces
        (assigns to the suit 1L aka the "red" suit).

                        Changes in version 0.1.1                        

Functions for reading/writing Portable Piecepack Notation (PPN) files:

  - read_ppn() parses Portable Piecepack Notation (PPN) files.
  - write_ppn() writes Portable Piecepack Notation files.

Functions for visualizing moves in a parsed game:

  - plot_move() visualizes moves in a parsed game via
    piecepackr::render_piece().
  - animate_game() visualizes moves in a parsed game via
    piecepackr::animate_game().
  - cat_move() and cat_game() visualizes moves in a parsed game via
    ppcli::cat_piece().

Interactive PPN viewers:

  - view_game() provides interactive PPN viewers with a choice of a
    {shiny} app and a {cli} command-line interface.
