Qt 5.14.2 is a bug-fix release. It maintains both forward and backward
|
||
|
|
compatibility (source and binary) with Qt 5.14.0 through 5.14.1.
|
||
|
|
|
||
|
|
For more details, refer to the online documentation included in this
|
||
|
|
distribution. The documentation is also available online:
|
||
|
|
|
||
|
|
https://doc.qt.io/qt-5/index.html
|
||
|
|
|
||
|
|
The Qt version 5.14 series is binary compatible with the 5.13.x series.
|
||
|
|
Applications compiled for 5.13 will continue to run with 5.14.

||

- QCollator:
|
||
|
|
* QTBUG-81673: Fixed a regression introduced in 5.14.0 that caused
|
||
|
|
QCollator not to operate with default-constructed QStrings and print a
|
||
|
|
warning on Windows.
|
||
|
|
|
||
|
|
- QString, codecs:
|
||
|
|
* QTBUG-62011: ZWNBS is no longer discarded (mistaken for a BOM despite
|
||
|
|
not being at the start) when converting UCS4 to QString's UCS2.
|
||
|
|
|
||
|
|
- QLocale:
|
||
|
|
* QTBUG-80459: Skip digit-grouping if the system locale is configured to
|
||
|
|
use an empty group separator.
|
||
|
|
* QTBUG-81530: Use "+" if MS reports empty for the system locale's plus
|
||
|
|
sign, as documented in MS's API for the relevant query.
|
||
|
|
|
||
|
|
- QLockFile:
|
||
|
|
* Suppressed the warning on QNX that said 'setNativeLocks failed:
|
||
|
|
"Function not implemented"'. There is no difference in behavior: Qt
|
||
|
|
will continue not to be able to apply an OS- level file lock, which
|
||
|
|
means the lock could be accidentally stolen by buggy software. Correct
|
||
|
|
software using QLockFile should not be affected.
|
||
|
|
|
||
|
|
- QObject:
|
||
|
|
* For the purposes of QT_NO_NARROWING_CONVERSIONS_IN_CONNECT, pointer
|
||
|
|
(incl. pointer-to-member) to bool conversions are now considered
|
||
|
|
narrowing. This matches the resolution of a defect report in C++
|
||
|
|
itself.
|
||
|
|
|
||
|
|
- QStorageInfo:
|
||
|
|
* Improved discovery of device nodes on Linux if the /dev entry was
|
||
|
|
renamed after the filesystem was mounted and udev is in use.

- QTextMarkdownImporter:
|
||
|
|
* Text in Markdown format is assumed to be UTF-8.
|
||
|
|
* The "title" in a Markdown hyperlink is now used as the tooltip,
|
||
|
|
not the anchor name.
|
||
|
|
* Fixed vulnerability oss-fuzz-20450 (invalid input resulted in an
|
||
|
|
attempt to insert items into a list that no longer exists).

- To remove the NDEBUG define that is added by default in MSVC mkspecs,
|
||
|
|
write DEFINES_RELEASE -= NDEBUG in your .pro file.
|
||
|
|
- Install/uninstall rules are now generated for target.targets on Windows.
|
||
|

This mirrors the behavior on Unix.

- Fixed build regressions.
|
||
|
|
- The -debug-and-release configuration has been fixed. In this
|
||
|
|
configuration, Qt libraries again have a 'd' suffix.
|
||
|
|
- In the -debug configuration, libraries do not have a 'd' suffix, similar
|
||
|
|
to Unix platforms.
