Release note

Qt 6.2.7 release is a patch release made on the top of Qt 6.2.6. As a patch
release, Qt 6.2.7 does not add any new functionality but provides bug fixes
and other improvements.

For detailed information about Qt, see the Qt 6.2 online documentation:
https://doc.qt.io/qt-6.2/.

Important Changes

qtbase

• e4659c13de Document QAtomic testAndSet
  Documented new overloads of testAndSet() that were originally added for
  5.3.

• 5036c971e8 QTaggedPointer: disable operator= with an empty initializer
  list
  The operator assignment taking a raw pointer has been reimplemented in
  order to avoid subtle issues when assigning {} to a QTaggedPointer.
  This will cause code that assigns a braced-init-list to a QTaggedPointer
  object to stop compiling (for instance, tagPtr = {ptr} is now ill-
  formed).

• 06cc44b7b7 Update bundled libpng to version 1.6.38
  libpng was updated to version 1.6.38

• 5f6bc72cd5 Fix generating PDFs with DirectWrite engine
  Fixed glitches in generated PDFs when the DirectWrite backend was in
  use, e.g. when high-dpi scaling was active.

• afdb88a263 Ensure proper format of Info.plist
  Fixed handling binary Info.plist files in generated Makefiles by always
  converting them to XML before substituting placeholders.

• 03b7d80071 Update bundled zlib to version 1.2.13
  zlib was updated to version 1.2.13.

• d7b3574088 macOS: Fix less common writing systems on Catalina and
  later
  Fixed missing text with certain writing systems on macOS Catalina and
  later.

qtdeclarative

• 8435926668 DA: ignore disabled HoverHandlers when delivering hover
  events
  Disabled hover handlers will no longer receive hover events, or block
  siblings from being hovered.

qttools

• 854684e99 qdoc: Enable correct linking to externally-built
  dependencies

qtwebengine

• in Qt 6.2.7, Qt WebEngine from Qt 6.4.1 is used

• c3ae834aa Add charset parsing to custom scheme handler's content type
  Charset is now explicitly parsed from provided contentType

• 82357352b Introduce "--webEngineArgs" to prevent unexpected sub-
  process args
  Command line arguments meant for webengine has to be now stated after "
  --webEngineArgs" option.

• 4c4ac0df9 Introduce http status code domain for loading info
  Added HttpStatusCodeDomain for http status code range of errors

• 196ec015c Add NavigateOnDrop settings
  NavigateOnDropEnabled added, enabled by default.

• 05d82c353 QPdfView: replace enums with enum classes
  All enums are replaced with enum classes.

• 6769bd154 Move QPdf namespace enums into QPdfDocumentRenderOptions
  enum classes
  The QPdf namespace is removed.

• 90f43fd25 Rename QPdfNavigationStack to QPdfPageNavigator; QML type
  too
  The PdfNavigationStack QML type has been renamed to PdfPageNavigator,
  matching the C++ type QPdfPageNavigator. These remember navigation
  history within a document, and are helpful to implement back/forward
  buttons similar to those on a web browser in both Qt Quick and widget-
  based viewer applications.

• 0de16e9a2 Redefine PdfSearchModel.currentResult as document-based; use
  PdfLink
  PdfSearchModel.currentResult is now the result index within the whole
  set of search results rather than on currentPage; and changing
  currentPage no longer makes currentResult change. In the views, this
  means the current highlighted search result stays on the same page even
  when the user views a different page.

• fd39e1eee Add link role to QPdfLinkModel, providing a QPdfLink
  instance
  PdfLinkModel now provides a QPdfLink object for each link. QPdfLink now
  contains everything necessary to render delegates for links and search
  results, and handle clicking links; and there is a copyToClipboard()
  method for use in context menus, which will copy the text returned trom
  toString(), which is also invokable.

• 66aca3c84 Add PdfLinkDelegate instead of link decoration style
  properties
  A PdfLinkDelegate will now be instantiated on top of each hyperlink in
  the PdfMultiPageView, PdfScrollablePageView and PdfPageView components,
  for event handling and to provide tapped() and contextMenuRequested()
  signals. It is non-visual by default, but can be customized, for example
  to draw underlines under hyperlinks if the PDF documents are not
  expected to have them already.
