| Qt 5.6.2 is a bug-fix release. It maintains both forward and backward | ||
| compatibility (source and binary) with Qt 5.6.0. | ||
|
|
||
| For more details, refer to the online documentation included in this | ||
| distribution. The documentation is also available online: | ||
|
|
||
| http://doc.qt.io/qt-5/index.html | ||
|
|
||
| The Qt version 5.6 series is binary compatible with the 5.5.x series. | ||
| Applications compiled for 5.5 will continue to run with 5.6. | ||

| * Important Behavior Changes * | ||
| ****************************************************************************** | ||
|
|
||
| - [QTBUG-45031] The NSURLConnection backend of QNetworkAccessManager has | ||
| been removed, since SecureTransport is the default SSL backend on iOS | ||
| and is enabled by default. This means that building with -no-openssl | ||
| -no-securetransport will no longer provide SSL capabilities on iOS. | ||
|
|
||
| - QUrl::resolved() no longer treats a URL with a scheme as a relative URL | ||
| if it matches this URL's scheme. For now it still treats "file:name.txt" | ||
| as relative for compatibility, but be warned that in Qt 5.8 it will no | ||
| longer consider those to be relative. Both isRelative() and RFC 3986 say | ||
| that such URLs are not relative, so starting from Qt 5.8, resolved() will | ||
| return them as is. | ||
|
|
||
| - [QTBUG-47815] QDateTime now uses QLocale to get the "AM" and "PM" strings | ||
| when parsing times, instead of strings obtained from the loaded | ||
| translations. | ||
|

| dialogs prompting the user to insert media when certain operations were | ||
| made with Qt I/O classes, particularly QStorageInfo::mountedVolumes(). | ||
|
|
||

| * [QTBUG-53071] Fixed a bug that caused QTimeZone to mis-parse time zones | ||
| whose names were not simple letter and digit combinations. | ||
|
|
||
| - QUrl: | ||
| * Made QUrl stricter in what it accepts for schemes, to comply with the | ||
| relevant standards. QUrl will no longer accept schemes starting with a | ||
| plus (+), a dash (-) or a dot (.). | ||
|
|
||
| - QVariant: | ||
| * [QTBUG-53384] Fixed QVariant::canConvert and conversion from integer | ||

|
||
| - [QTBUG-50724] Added support for clang compiler. | ||
| - [QTBUG-53511] Fixed CJK font resolution on Android 7. | ||
|
|
||
| BSDs | ||
| ---- | ||
|
|
||
| - The freebsd-g++ mkspec was moved back and no longer requires the | ||
| "unsupported/" prefix, matching the FreeBSD ports tree, as FreeBSD 9.3 | ||
| still defaults to using GCC. Users of GCC that did not previously use | ||
| the ports patch will need to adapt their build scripts and drop the | ||
| "unsupported/" prefix. | ||
| - Fixed a number of compilation issues on FreeBSD, NetBSD and OpenBSD. Qt | ||
| should now build out-of-the-box (no patches needed) on those systems. | ||
|
|
||
| Linux | ||
| ----- | ||
|
|
||
| - [QTBUG-54733] It is now possible to opt out from installing signal | ||
| handlers when running with eglfs and linuxfb by setting the | ||
| QT_QPA_NO_SIGNAL_HANDLER environment variable to a non-zero value. | ||
|
|
||
| macOS | ||
| ----- | ||
|
|
||
| - [QTBUG-48953] Pasting text from Qt applications to Apple Mail now works. | ||
| - [QTBUG-48953] “text/vcard” is now required as the mime type when | ||
| placing vCards on the clipboard. | ||
| - OS X => macOS rename in Q_OS_ macros/docs, qmake scopes, | ||
| file selectors, etc. | ||
| - Add new QSysInfo values and MAC_OS_X / __MAC_ / __IPHONE_ values for | ||
| macOS 10.12 and iOS 9.1 through 10.0. | ||
| - Update prettyProductName with new macOS "Sierra" codename. | ||
|
|
||
| Windows | ||
| ------- | ||
|
|
||
| - Fixed a new[]/delete mismatch in Windows tablet support. | ||
|
|
||
| X11 / XCB | ||
| --------- | ||
|
|
||
| - Fixed the value of the 'defined' field in ATSPI GetAttributeValue | ||
| results. | ||
