Version 2026.1.20.0

Changes made in this release:

Fixed the standalone GUI so that it uses the Visual Studio 2022 build tools or later as the minimum. This prevents builds that generate help 1 (CHM) files from failing due to an incompatibility with the Visual Studio 2019 build tools.
The help file builder can now be used as part of a GitHub workflow.
Added a new presentation style, Themed2026, which is now the default for new projects.
- Removed the CollapsibleSection and LogoUrl transformation arguments.
- Added a ProjectUrl transformation argument that replaces the LogoUrl transformation argument. If specified, it places a link button in the page header.
- Added support for switching between light and dark themes. It uses the system preference by default.
- Lunr is used for search functionality and allows for required search terms, excluded search terms, wildcard searches, term level boosting, and fuzzy searches. The search results also show the start of the topic content to provide some more context. Search index data is stored in two JSON files rather than the multiple files used previously. Although they are much larger overall, the trade off is a much better search experience.
- Table of contents information is stored in a single, compact JSON file eliminating the many XML fragment files used previously resulting in an overall size reduction between 50% and 75% for most projects.
