This is a minor release in the Asciidoctor PDF 2 release line. This release includes several enhancements and bug fixes.
Enhancements. If you set the media to print or prepress, and you don't specify a theme, Asciidoctor PDF will now use the built-in default-for-print theme by default. This change makes it easier for users to get print-optimized output by default and raises awareness about the existence and function of this theme. If you want to force a page break, you can now add [%always] above the page break macro. If you producing a multi-column layout (e.g., page-columns is > 1), the page break macro will create a new page by default. If you want to start a new column, add the column role to the page break macro. If you want to place footnotes (aka endnotes) directly below the last block of content, set the footnotes-margin-top key to 0 (or another fixed value) in your theme. If you use the big and small roles, the text will be scaled relative to the font size of the surrounding text, even when used in headings. The converter now recognizes the text alignment roles (e.g., .text-center) on all styled paragraphs and verse blocks.
Bug fixes. Some users prefer to add additional markup to code blocks to emphasize tokens. When the source highlighter is enabled, Asciidoctor PDF does not support this extra markup. However, rather than printing it verbatim, the converter will now strip it away to maintain the integrity of the code in the code block. If a footnote label falls at the end of a line, it will no longer be split or widowed. Instead, it will stay together and with the preceding adjacent text, pulling that the last word to the next line if necessary. If the prose-margin-inner and/or prose-text-indent-inner theme keys are set, these are now honored on inner paragraphs in the abstract. If the prose-text-indent key is set in the theme, it will only be applied to elements that have a left-oriented alignment (left or justify). The computed height of headings and captions for orphan prevention now takes into account all text formatting, making the behavior more accurate.
During this release cycle, numerous improvements were made to the documentation as well.
allow page background image to be specified per layout using +{page-layout}+ attribute reference in path (#1739)
allow page margin for rotated page to be configured independently using page-margin-rotated theme key or pdf-page-margin-rotated document attribute (#1719)
allow orphan detection to be enabled for all section titles and discrete headings by setting heading-min-height-after to auto in theme (#2268)
set docimagesdir attribute when attribute substitutions are applied to value from theme (#2278)
start page numbering and running content on empty verso page before first chapter of prepress book if start-at value is 0 (#2252)
don't force page break after TOC with automatic placement in article if title-page attribute is set and value of toc-break-after theme key is auto (#1768)
add --theme option to CLI as shorthand for -a pdf-theme (#2250)
add --sourcemap option to CLI to enable :sourcemap option on processor (#2265)
broaden support for relative font sizes in theme to more than just inline elements; document support for relative font sizes
allow theme to control font properties of marker for ordered list using olist-marker category (#2279)
allow theme to control font style of marker (per marker or all markers) for unordered list
Improvements::
add internal Document#attr_unspecified? method to simplify check for an attribute which has not been set or unset
