changed lines [17] of file "/tmp/updatecli/github/asciidoctor/docker-asciidoctor/Dockerfile"

2.3.18

Release published on the 2024-07-27 19:11:01 +0000 UTC at the url https://github.com/asciidoctor/asciidoctor-pdf/releases/tag/v2.3.18

This is a patch release in the 2.3.x release line to fix one bug and address one Ruby 3.3 compatibility issue.

If the page layout changes, the foreground image is now positioned correctly. The version lock on the rexml gem has been released now that the upstream issue has been resolved. The rexml upgrade does not require building native extensions in the strscan gem, but this is unavoidable since it was a change in Ruby itself.
