[dependabot]

Updates the requirements on asciidoctor to permit the latest version.

Release notes

Sourced from asciidoctor's releases.

v2.0.24

This is a patch release in the 2.0.x release line to fix bugs and address compatibility and compliance issues.

After upgrading, you'll no longer see the warning about the use of the logger gem when using Ruby 3.4. This is only a short-term solution for Ruby 3.4 and will need to be permanently fixed in a future release for Ruby 3.5. On the topic of logging, an error is now logged if an unterminated preprocessor conditional directive is detected. If the sourcemap option is enabled on the processor, the message will identify the file and line where the conditional started. (This change also allowed us to uncover cases when the conditional stack was incorrect). If you are extending Asciidoctor Logger class to implement a custom logger, all kwargs are now passed to the superclass correctly.

If you're converting to DocBook, you will notice that the link attribute on an inline image is supported (but not yet for a block image). For reproducible builds, the SOURCE_DATE_EPOCH environment variable is now ignored if empty.

If you're writing a converter from scratch, you'll find the documentation on how to get started to be much more helpful. You'll also appreciate the fact that the converter will not crash if you're missing a convert handler for a node when extending the base converter.

When using the verse block, you'll notice that the code tag no longer displays as a block.

Finally, two changes have been made for better compatibility with Opal to support Asciidoctor.js.

Distribution

• RubyGem (asciidoctor)
