Changelog

1.2 (2025)

• MantisBT 2.25+ compatibility — updated MantisCore version requirement
• Fixed CSP compliance — replaced inline <script> variable injection with an external pages/vars.php served as application/javascript; replaced $.getScript() (which uses eval(), blocked by MantisBT's script-src 'self' CSP) with a static defer script tag
• Fixed config page — replaced removed html_page_top()/html_page_bottom() with the MantisBT 2.x layout API (layout_page_header, layout_page_begin, layout_page_end) and updated the form markup to Bootstrap
• Updated DOM selectors — now correctly targets div.bug-attachment-preview-image and sets href to the show_inline URL so Lightbox2 can render the image
