Qt 5.12.5 is a bug-fix release. It maintains both forward and backward
|
||
|
|
compatibility (source and binary) with Qt 5.12.0 through 5.12.4.
|
||
|
|
|
||
|
|
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 5.12 series is binary compatible with the 5.11.x series.
|
||
|
|
Applications compiled for 5.11 will continue to run with 5.12.

||

|
|
- QBitArray:
|
||
|
|
* Fixed two bugs that caused QBitArrays created using fromBits() not to
|
||
|
|
compare equal to the equivalent QBitArray created using other methods
|
||
|
|
if the size was zero or not a multiple of 4. If the size modulus 8 was
|
||
|
|
5, 6, or 7, the data was actually incorrect.
|
||
|
|
|
||
|
|
- QCborStreamReader:
|
||
|
|
* Fixed a bug that caused the QIODevice that the data was being read
|
||
|
|
from not to show the entire CBOR message as consumed. This allows the
|
||
|
|
user to consume data that may follow the CBOR payload.
|
||
|
|
|
||
|
|
- QCryptographicHash:
|
||
|
|
* Fixed a bug that caused the SHA-3 and Keccak algorithms to crash if
|
||
|
|
passed 256 MB of data or more.
|
||
|
|
|
||
|
|
- QObject:
|
||
|
|
* Fixed a resource leak caused by a race condition if multiple QObjects
|
||
|
|
were created at the same time, for the first time in an application,
|
||
|
|
from multiple threads (implies threads not started with QThread).
|
||
|
|
|
||
|
|
- QStorageInfo:
|
||
|
|
* Fixed a bug that caused QStorageInfo to be unable to report all
|
||
|
|
filesystems if the options to mounted filesystems were too long (over
|
||
|
|
900 characters, roughly), such as those found in Docker overlay
|
||
|
|
mounts.
|
||
|
|
|
||
|
|
- QTimeZone:
|
||
|
|
* The IANA timezone database backend now properly follows symlinks even
|
||
|
|
when they point to variable locations like /run or /var (useful when
|
||
|
|
/etc is mounted read-only).

* Improve loading time when loading png files that have the same size as

|
|
the target.

- QPixmapCache:

|

|

- Text:

|
||
|
|
larger than it was supposed to.
|
||

- QHostInfo:
|
||
|
|
* Functors used in the lookupHost overloads are now called correctly in
|
||
|
|
the thread of the context object. When used without context object,
|
||
|
|
the thread that initiates the lookup will run the functor, and is
|
||
|
|
required to run an event loop.
|
||
|
|
|
||
|
|
- Windows:
|
||
|
|
* Correctly emit errors when trying to reach unreachable hosts or
|
||
|
|
services

sure the user sees the dialog.
