    - Customize the tables of content by providing a template.
      The template is processed as a song before the tables
      and can be used to set title, subtitle, columns, maybe even an
      introduction text. Since the template it iself a song, it can be
      associated with its own config file for unlimited customization.

    - New delegated environment: textblock. The text between
      start_of_textblock and end_of_textblock is formatted normally,
      but the result is an image that can be placed anywhere. Several
      attributes are available to control the appearance of the text,
      e.g. centered and flush right.

    - Delegate type may now also be 'omit' to omit the content of the

    - Images can be [placed everywhere](https://chordpro.org/chordpro/directives-image/).
      They can be placed relative to the paper, the page, the column,
      and the lyrics.

    - Images can be [embedded](https://chordpro.org/chordpro/directives-image/#inline-images) in text (lyrics) lines, either as part of
      the text similar to a glyph, or somewhere else on the page
      relative to a particular place in the text. The latter is most
      interesting for annotations.

    - Delegates are images too. Annotate your lyrics with SVG images
      and musical notes using ABC or Lilypond.

    - Chord and keyboard diagrams are images too. And you can use
      string and keyboard diagrams simultaneously.

    - Resources like configs, tasks and images are now more logically
      searched using [resource
      libraries](https://chordpro.org/chordpro/resources/).

6.030 2023-09-18

    - !Highlights

    - [ABC](https://www.chordpro.org/chordpro/directives-env_abc/)
      and [Lilypond](https://www.chordpro.org/chordpro/directives-env_ly/)
      embedding now use SVG (vector graphics) instead of pixmap images.
      This is very crisp at all sizes, and
      greatly reduces the size of the resultant PDF document.
      + No additional tools are required for embedding, except the
      `abc2svg` and `lilypond` tools. The installer kits for MS
      Windows and MacOS already include the `abc2svg` tool.

    - The ChordPro GUI (`wxchordpro`) has been extended with a Tasks
      menu that can be used to quickly select presets for a specific
      task. For example, to produce a PDF with only lyrics, or with
      keyboard diagrams instead of string diagrams. User presets can
      be added by placing small config files in a `tasks` folder under
      the `CHORDPRO_LIB`.

    - !ChordPro functionality
