Changes in version 0.2.2                        

  - Added 'pixeltrix' class to matrix objects output by click_pixels()
    and edit_pixels(), and included is_pixeltrix() and as_pixeltrix() to
    detect and coerce (#36, thanks @trevorld).
  - Added warning to README and function docs about flickering and the
    bell (#31, #32, thanks @adrianadepalma).

                        Changes in version 0.2.1                        

  - Added additional input checks to check-utils.R.
  - draw_pixels() now finds n_states (#24).
  - Allow for an increased number of states in edit_pixels() (#25).

                        Changes in version 0.2.0                        

  - A named character of colours is now provided as an extra attribute
    to matrices output from click_pixels() (#3, #17, thanks @TimTaylor).
  - A named character vector of colours is now accepted as input to
    click_pixels(), edit pixels(), draw_pixels() and frame_pixels().
  - Breaking: blue and mario demo datasets no longer available;
    pkmn_sprite and mario_frames replace them (#22).
  - Updated and expanded function documentation and README (#21).
  - Reused input checks have been generalised into R/utils-check.R.

  - Fixed lack of n_states() being passed to edit_pixels() in
    frame_pixels() (#18, thanks @TimTaylor), replacing dots in
    frame_pixels() with full set of arguments to pass to click_pixels()
    and edit_pixels().
  - Altered slightly the title and description of the package.
  - Set default canvas dimensions to 8 by 8.

  - Added draw_pixels() to plot the matrix with image() to the plotting
    window (#12).
  - Added frame_pixels() and gif_pixels() to capture successive 'frames'
    of an animation and write it to a gif (#13).
  - Suggested {gifski} for creating gifs (towards #15).
  - Provided to the user some instruction messages when they enter
    interactive mode.
  - Improved code commentary.
  - Added two matrix outputs as example datasets (Pokemon and Mario).

  - Added basic error tests.
  - Allowed for single row and single column matrices to be accepted by
    click_pixels() and edit_pixels() (#4).
  - Removed redundancies in function documentation.
