+Behavior Changes
+----------------

+   service, and now runs in a separate sandboxed process by default.

+*                                 Qt PDF                                   *
+****************************************************************************
+
+General
+-------
+
+ - The qt-labs/qtpdf module was using an out-of-date version of pdfium.
+   Development will now continue in the qtwebengine repository in order to
+   reuse Qt WebEngine's pdfium build system integration.
+ - QtPdf is still in Tech Preview.
+ - It's now possible to build QtPDF for iOS (even though Qt WebEngine does not).
+ - Added a Qt Quick API (import QtQuick.Pdf):
+   * Added an image plugin: Image { source: "my.pdf"; currentFrame: 2 } is
+     enough to view the third page in a PDF file.
+   * High-level API for full-featured viewers: PdfScrollablePageView shows
+     one page at a time; PdfMultiPageView allows flicking vertically from
+     page to page. These are implemented in QML and packaged with the module.
+ - Low-level QtQuick API:
+   * PdfDocument provides API for the document and its metadata.
+   * PdfSearchModel can find a text string and provides information about
+     the locations where it is found on each page, which can be listed in
+     a ListView and visualized by using a Repeater to instantiate
+     QtQuick.Shapes for the bounding boxes.
+   * PdfSelection allows selecting text and copying to the clipboard;
+     visualization of the selected region is done via QtQuick.Shapes.
+   * PdfLinkModel provides information about the links in the document;
+     visual feedback and clicking can be handled with QtQuick.Shapes
+     and TapHandler, respectively.
+   * PdfNavigationStack is a model for implementing forward/back navigation.
