New/removed/moved bridge Collectors

Changes to widgets

  • jQuery is removed, and widgets are now Javascript classes. Custom widgets should be updated.
  • FontAwesome is removed, and replaced by SVG icons from Tabler, included in CSS. Only the icons used by the default widgets are included, so packages extending the debugbar should add their own icons.
  • Typehints are added to all widgets, so you might need to update your widgets.
  • Widgets are rendered when opening a tab, not when loading the page.

Changes to DataCollectors

  • TimeDataCollector is removed from the constructors, but a setTimeDataCollector method is added.
  • useHtmlVarDumper is removed. The HtmlDataFormatter is used by default. To use plain-text, the the default formatter to DataFormatter.

Remove obsolete methods

  • Removed get/setBindAjaxHandlerToJquery (Use bind to fetch/xhr instead)
  • Removed Assetic collection (use getAssets() directly if needed)
  • Removed RequireJS support
  • Removed captureVar and renderCapturedVar from DebugBarVarDumper

Breaking changes to methods/interfaces

  • Everything is typehinted, so you might need to update your code for custom collectors.
  • getAssets() removed the $type parameter and always returns all assets.
  • OpenHandler requires the op parameter to be always set.
  • The DataFormatterInterface has a 2nd 'deep' parameter to formatVar.
  • The StorageInterface has a new 'prune' method

Other changes

  • Storage now uses json instead of serialize, so old data cannot be read.
  • PDO now quotes using the PDO connection when available. The quotation char is now always '. Methods have moved to the QueryFormatter instead of TracedStatement.
  • The DataFormatterInterface has a 2nd 'deep' parameter to formatVar.
