WebViewer Server


Version 4.0.1 Changelog (2018-10-26)

In this document


  • If an inline svg is used in a custom button, it would adapt the UI’s color

  • Hot-reloading has been enabled for webviewer-ui, improving dev experience when customizing the source code of webviewer-ui

  • Priorities have been set between features and elements. For example, if the UI

    1. Disables stickyToolButton element,
    2. Disables notesPanel feature,
    3. Enables annotation feature,

    even if the sticky tool button and notes panel are part of annotation feature, they will still be disabled (specific rules wins over general rules).
