The changes include:

• Please refer to the migration guide for more information as these changes might impact existing integrations.
• A new JavaScript engine, based on GraalJS, is used by default. (See features)
• The font-size values "larger" and "smaller" are now larger/smaller than the parent font-size by a factor of 1.2, matching browser behavior.
• The automatic document type detection has been improved and now also takes the file extension into account. (#8687)
• PDF Tagging now processes ARIA attributes in HTML and automatic tagging has been further improved. We recommend re-validating if the tag structures of your documents are still as expected. (See features)
• Generated content on replaced elements is now ignored, as required by the specification. (#9283)

• Running Elements may disappear when using "MathJax". (#7338)
• File locks on font files are kept after the conversion has finished, up to the termination of the JVM. (#6354)
• In a rare specific case links cause the output PDF to be corrupted. (#8702)
• "BookletMode" API setting swaps left and right pages and "BOOKLET_RTL" page order reverses order of sheets. (#9284)
• When using "pagesPerSheet" with raster image output the pages are scaled incorrectly. (#9179)
• Some dependencies are outdated, containing CVEs.
• Exceptions
  • Certain documents with fragmented floated elements can cause exceptions. (#9063)
  • Certain combinations of tables and flex layout cannot be laid out, causing an exception. (#8953)
  • An exception is caused by flex-items that have an aspect-ratio of zero. (#9075)
  • Using "-ro-scale-content" in conjunction with forced page breaks on grid items can cause exceptions. (#8858)

  • Text overflows line when the last part is in a different element and starts with certain characters, like colons. (#9287)
  • The synthetic baseline of replaced elements, like images, is the bottom border edge instead of the bottom margin edge. (#8470)
  • Font kerning is not applied correctly around invisible soft hyphens. (#8683)
  • In rare cases large fonts embedded into PDFs were missing some glyphs, causing missing text, or error messages in some viewers. (#8660, #8698, #8709, #9037)
  • When bold text is rasterized, e.g. due to text-shadow, superfluous synthetic bold might be applied. (#8810)
  • Text with "vertical-align: super" and "line-height: 0" shifts its line downwards. (#8924)
  • In certain cases empty pseudo elements cause superfluous line breaks. (#8705)
  • Empty inline elements are not positioned correctly in their line. (#8652)
• CSS
  • The declarations of page margin rules inside the same page rule do not cascade. (#8715)
  • Setting a CSS shorthand property and retrieving the corresponding longhand properties via JavaScript, or vice versa, i.e. setting longhands and retrieving shorthand, does not return the set values. (#4905, #7197)
  • When CSS shorthand properties with a CSS variable as a value are marked as important, they can still be overridden by non-important longhand properties. (#8806)
  • The proprietary rule "@-ro-preferences" is only recognized when defined on the top level of the style sheet and not when it is inside another rule (e.g. "@media"). (#9023)
  • Negative padding is erroneously used if it is the result of a calc-function. (#8999)
  • Page margin boxes can be created even if their "content" property is "none". (#8736)
  • Very large CSS counter values are imprecise. (#8672)
• Floats
  • In certain cases, elements that contain a floated element which itself was moved to the next page during layout, have a height that is too large. (#8610)
  • Under rare circumstances elements inside floated elements overlap with content of other floats. (#8845)
• Tables
  • The height attribute is not supported on all table-related HTML elements. (#9050)
  • Table content is laid out in incorrect order in special circumstances. (#8821, #8955)
  • Large table captions can lead to overflowing table content. (#9100)
  • The page break behavior of tables is incorrect when the table has a fixed height. (#8734)
  • Incorrect table bottom border if "break-before: avoid" is set on table rows. (#8569)
  • Tables with collapsed borders and "box-decoration-break: slice" are broken onto the next page even if they would barely fit on one page. (#8551)
  • The distribution of heights in tables differs from browser behavior. (#8829, #8141)
  • The height of a fragmented row spanning cell is wrong under certain circumstances. (#7977, #7882)
  • Fast table layout ("display: -ro-fast-table") does not respect border widths, possibly leading to overlapping cells. (#8918)
  • Fast tables ("display: -ro-fast-table") now have limited support for font fallback and "vertical-align", specifically "middle" and "bottom" in addition to "top". (Note: HTML tables default to middle.) (#8917)
• Flex
  • The width and height of flex items is incorrect in certain complex cases of nested items. (#8375)
  • Percentage or aspect-ratio based sizes of flex items are incorrect in certain cases. (#8411, #8675)
  • Wrapped column flex items with greatly varying sizes may overflow the page. (#9190)
  • Flex containers with multiple lines and a specified height are not fragmented correctly between flex lines. (#8860)
  • Items in nested column flex containers can be shrunk excessively instead of being distributed across pages. (#9278)
  • When using automatic scaling to avoid overflow, certain flex layouts can cause documents to be scaled down excessively. (#8861)
  • Nested flex containers with "height: 100%" are laid out incorrectly and overlap. (#8741)
• Multi-Column
  • Absolutely positioned elements inside a multi-column container should not be positioned relative to their column (can optionally be re-enabled). (#9079)
  • Absolutely positioned elements directly before column span elements can cause missing content. (#9291)
  • Page breaks inside of spanning elements in multi-column layouts are not avoidable. (#9265)
  • In some cases dynamic changes to the height of elements inside a multi-column container lead to empty columns or pages. (#8745)
  • Certain complex layouts lead to incorrectly named strings and seemingly empty columns or pages. (#8892)
  • Multi-column balancing ignores the values of the CSS properties "orphans" and "widows". (#8616)
  • In certain cases CSS styles for break avoidance are ignored during column balancing. (#5241, #8888)
  • The margins at the bottom of the last column of a multi-column element or the last region of a region chain are incorrectly truncated to zero. (#8605)
  • Empty block at the end of multi-column content has unexpected impact on layout. (#9171)
• Counters
  • The value of counters is incorrect when they follow an explicit nested counter of the same name. (#8620)
  • In rare cases the layout of complex documents causes certain target-counters to have outdated values. (#8887, #8889)
  • In rare cases target-counters are not updated correctly due to dynamic changes made via JavaScript. (#8703)
• CSS Custom Properties
  • Custom properties with a value of "initial" are not treated as invalid and CSS variables that use their fallback are not resolved correctly in certain cases when the fallback is also a CSS variable. (#9157)
  • Custom properties starting with a number are ignored. (#8944)
• Footnotes
  • Paragraphs that contain many footnotes may be moved to the next page as a whole instead of moving only a few lines, when there is not enough space left for all footnotes. (#8537) (See features)
  • Manipulating footnotes via JavaScript can cause incorrect layouts. (#8539)
  • Footnotes are missing due to certain combinations of styles. (#8752)
  • Footnote markers may overlap each other when "overflow-wrap" is set to "anywhere". (#8926)
• Margins, Borders and Backgrounds
  • When the CSS property "background" specifies both an origin and a clip rectangle, the value is treated as invalid. (#9145)
  • The visualization of the "outline" property ignores the border-radius of the element. (#8970)
  • Under certain circumstances the repeating background image of an element is repeated once too often, which is invisible but noticeable in PDFs. (#9062)
  • Margins are collapsed incorrectly when the respective elements directly follow empty blocks. (#8656)
  • Margin-bottom is used as margin-top under special circumstances. (#8971)
  • "box-decoration-break: slice" behaves as "clone" under special circumstances. (#6872)
• Image Input
  • Some types of TIFF images are converted incorrectly. (#7733, #7735)
  • The size of an SVG image is wrong under special circumstances. (#9001)
  • The "patternTransform" SVG attribute is not applied when converting to PDF. (#9159)
  • The XHTML cleanup tool "Cyberneko" breaks embedded SVGs. (#8684)
  • When PDFs are used as images some raster images in those PDFs appear inverted or incorrectly colored in the PDFreactor Preview or in raster image output. (#9081)
  • Image has incorrect colors after resampling, auto-conversion to CMYK, PDF/X conformance, and using ICC profile. (#9191)
  • SVG "symbol" elements are not found when their root SVG element has "display: none" set. (#7092)
• List Items
  • List item marker position is wrong if the list item only contains an empty block element. (#8972)
  • Alignment of list item marker is wrong under special circumstances. (#7368)
  • The paint order of list item markers is incorrect. (#8409)
• PDF Forms
  • Field values of radio button groups are incorrect when the first button is not checked. (#8573)
  • Radio buttons cause duplicate annotations in the PDF. (#8500)
• PDF Tagging and Accessibility
  • Clipped content, e.g. through the "clip-path" property, is not added to the PDF at all and so not available to screen readers. (#8561)
• PDF Gradients (from CSS, SVG or Canvas) (See features)
  • Color space conversion of PDF gradients with varying alpha values is inaccurate. (#8060)
  • The color components of fully transparent color-stops incorrectly bleed into the neighboring color transitions. This for example causes gray tinges when the "transparent" color keyword is used. (#9219)
  • Radial gradients with different center and focus points are converted to PDF gradients with the same coordinates for both points.
• Barcodes
  • The subtypes of Telepen, Code 2of5, Postnet and DataBar barcodes are not applied correctly.
  • Baseline positioning of human-readable text is incorrect when font size is not default. (#8733)
• Logging
  • The message logged, when rasterized elements (e.g. when using the CSS properties "filter" or "box-shadow") are too large, does not provide enough information. (#8607)
  • When a conversion is aborted due to a potentially malicious SVG the exception does not clearly state that. (#8862)
• Segmentation
  • Enabling PDF tagging nullifies the memory saving effects of segmentation. (#9205)
• Performance
  • Conversions of documents with many duplicate IDs and target-counters are unexpectedly slow. (#9197)
  • The layout of deeply nested grid layouts is slow. (#9048)
  • Large data-URIs can slow down conversions significantly. (#8781)
• PDFreactor Web Service
  • Cannot convert documents from string with more than 20,000,000 characters. (#9052)
  • A connection timeout occurs when debug mode is enabled and loading of a resource from a network drive fails. (#7033)
  • It is not possible to override the "User-Agent" header sent by PDFreactor Client requests. (#8682)
  • The service's automatic temporary file cleanup also removes empty directories without validating their age. (#8692)
• Documentation and Samples
  • Client samples use file URLs as input documents. (#8627)
  • Various documentation-related issues. (#9254, #8922, #8859, #6775)

The new features and improvements include:

• The new configuration property "inspectableSettings" enables the creation of documents that contain extensive layout and style metadata. Those documents can be analyzed using the PDFreactor Inspector (currently in beta). Please see pdfreactor.com for further information.
• Support for CSS Grid Layout. (#6894)
• The CSS property "float" now supports the values "-ro-top" and "-ro-bottom", which turn boxes into page floats, i.e. floats them vertically to the top or bottom of their page or column. (#6315)
• Added support for HTML image maps. (#8020)
• Introducing new barcode functionality, controlled entirely via proprietary CSS and adding support for many new types, including "Aztec Code" and "MaxiCode", deprecating the previous functionalities. (#3170, #5599, #5659)
• Support for the visual CSS properties "clip-path", "mix-blend-mode" and "empty-cells" has been added. (#7528, #7582, #8235)
• The new proprietary pseudo-elements "::-ro-before-break" and "::-ro-after-break" allow specifying continuation markers that will be visible at every break between the pages the element is fragmented across. (#6823)

• The new proprietary value "-ro-scale-down" of the CSS property "text-overflow" allows visually scaling down paragraphs that overflow at the end of lines to automatically make their text fit their width. (#7987)
• Absolutely positioned elements can now be placed relative to the trim or bleed box via the proprietary CSS property "-ro-position-origin", which can override their containing block to any page box. Also, the default containing block determination has been improved, mostly for page boxes. (#6140, #7843)
• Encoding detection from content, like HTML "meta" elements with "charset", is now more robust. Heuristic detection from the text content has also been improved. (#7316)
• Orientation and resolution are now read from image metadata, like EXIF. The orientation is applied automatically, but can be overridden via the CSS property "-ro-image-orientation".

• Digital signature fields can now be added to PDF forms via the proprietary CSS property "-ro-pdf-signature-field-name". (#6720)
• PDF pages can now be rotated (in PDF viewers that support it) in 90° steps via the new proprietary CSS property "-ro-pdf-page-rotation". (#7293)
