Qt 5.5.1 is a bug-fix release. It maintains both forward and backward
|
||
|
|
compatibility (source and binary) with Qt 5.5.0.
|
||
|
|
|
||
|
|
For more details, refer to the online documentation included in this
|
||
|
|
distribution. The documentation is also available online:
|
||
|
|
|
||
|
|
http://doc.qt.io/qt-5.5/
|
||
|
|
|
||
|
|
The Qt version 5.5 series is binary compatible with the 5.4.x series.
|
||
|
|
Applications compiled for 5.4 will continue to run with 5.5.

- [QTBUG-47316] QDebug output for QStrings changed compared to Qt 5.5.0 to
|
||
|
|
more closely match the output of previous Qt versions. Like Qt 5.5.0,
|
||
|
|
QDebug will escape non-printable characters, the backslash and quote
|
||
|
|
characters, but will no longer escape the printable characters.

|
- Qt 5.7 will begin requiring certain C++11 features in order to
|
||
|
|
compile. Due to bugs in the Clang compiler that comes with XCode 5.0,
|
||
|
|
that version will not be supported, despite what was noted in the Qt
|
||
|
|
5.5.0 changelog.
|
||
|
|
The minimum compiler versions for Qt 5.7 release will be:
|
||
|
|
* Clang 3.3 (XCode 5.1 contains version 3.4)
|
||
|
|
* GCC 4.7
|
||
|
|
* Intel C++ Composer XE 2013 SP1 (compiler version 14.0) on Linux and OS X
|
||
|
|
* Intel C++ Composer XE 2016 (compiler version 16.0) on Windows
|
||
|
|
* Microsoft Visual Studio 2012 (compiler version 17.0)

|
|

|
||
|
|
display the same value, instead of the time since boot.
|
||
|
|
|
||
|
|
- QDate/QTime:
|
||
|
|
* Fixed a minor source-incompatibility between Qt 5.4 and 5.5.0
|
||
|
|
involving sets of functions overloaded on QTime and some integer or
|
||
|
|
QDate and some integer.

- QLoggingCategory:
|
||
|
|
* Fixed behavior of default severity passed to constructor or
|
||
|
|
Q_LOGGING_CATEGORY with regards to QtInfoMsg, which was previously
|
||
|
|
treated as being more severe than QtFatalMsg.

|
|
||
|
|
- QTimeZone:
