Latest version's change log

Version 10.4.0.281 – Release date: Mar 3, 2026

  • New copy and paste operations for library items, supporting both within-project and cross-project use, and optimized for large libraries
  • Added true AND support for required terms (+word) and full quoted-word matching in the default HTML template's built-in search engine, and fixed several edge-case filtering and exclusion bugs
  • Added optional accent-insensitive search to the default HTML template, allowing unaccented queries to match accented words
  • Added breadcrumb hierarchy hints to the auto-completion dialog: hovering over a topic now reveals its full path to help differentiate similar items
  • Hovering over a Reference now displays content from both its HTML and Report formats
  • Equation editor improvements: Faster performance, enhanced accessibility, improved scientific-notation handling with auto-formatting, plus multiple bug fixes
  • Fixed an issue where hidden topics in the table of contents were still included in the exported Markdown table of contents
  • Resolved an issue causing HTML documentation anchor links to scroll to the wrong position after page load in some cases
  • Improved accessibility in the default HTML template by correcting ARIA keyboard navigation so the first valid search result receives focus when the user tabs into the results
  • HTML search engine performance has been enhanced through internal preprocessing and scoring optimizations, making repeated and complex queries noticeably faster
  • HTML search engine now handles repeated required words correctly: entering the same +required term multiple times behaves like a single requirement and no longer changes filtering or ranking
  • HTML search engine with equal-score search results now use a stable topic order, giving consistent and predictable result lists across runs
  • Improved usability and accessibility of the HTML template's tree controls, including smoother keyboard navigation, clearer focus behaviour, and better screen-reader support
  • Corrected the behavior of open/save file dialogs that could lead to Access Violation errors under certain environments
  • Hardened the HTML template JavaScript library to safely handle edge cases in both default and custom templates
  • Resolved a bug that caused some hints to render without content in the topic editor
