Aspose.HTML for Java V26.9.19 de set. de 2026
Recursos
- Improved the internal calculation algorithm for layout units, including arithmetic operations and conversion to floating-point values. The updated implementation provides more accurate and consistent handling of layout units throughout the rendering pipeline.
- These changes affect multiple components of the HTML rendering engine, including box geometry and positioning, block and inline layouts, absolute and flex layouts, tables, columns, page layout, text, backgrounds, percentages, replaced elements, and SVG rendering. This improves the consistency and accuracy of layout calculations across the rendering engine.
- Significantly expanded the range of API classes that implement the java.lang.AutoCloseable interface. This enables more Aspose.HTML objects to be used with Java's try-with-resources statement, providing more convenient and reliable automatic resource management.
- The Document class is among the updated types. As a result, HTMLDocument and SVGDocument can now be used with Java's try-with-resources statement.
Correções
- MHT to PDF: Exception Incompatible unit types.

Aspose.HTML for Java V26.8Versão principal31 de ago. de 2026
Recursos
- Improved Markdown syntax processing and parsing stability.
- Extended MarkdownSyntaxFactory with support for creating and validating link titles, link destinations, and link labels. The new functionality provides consistent parsing and validation of Markdown link components, including validation of label syntax and length.

Correções
- Updated Hugo YAML front matter content handling to correctly account for platform-specific newline sequences when trimming serialized YAML content.
- Fixed emphasis processing in the Markdown parser by correcting delimiter stack traversal relative to the specified lower boundary. This improves the handling of emphasis delimiters in complex Markdown structures.
