1Qt 5.14.2 is a bug-fix release. It maintains both forward and backward 2compatibility (source and binary) with Qt 5.14.0 through 5.14.1. 3 4For more details, refer to the online documentation included in this 5distribution. The documentation is also available online: 6 7https://doc.qt.io/qt-5/index.html 8 9The Qt version 5.14 series is binary compatible with the 5.13.x series. 10Applications compiled for 5.13 will continue to run with 5.14. 11 12Some of the changes listed in this file include issue tracking numbers 13corresponding to tasks in the Qt Bug Tracker: 14 15https://bugreports.qt.io/ 16 17Each of these identifiers can be entered in the bug tracker to obtain more 18information about a particular change. 19 20**************************************************************************** 21* QtCore * 22**************************************************************************** 23 24 - QCollator: 25 * QTBUG-81673: Fixed a regression introduced in 5.14.0 that caused 26 QCollator not to operate with default-constructed QStrings and print a 27 warning on Windows. 28 29 - QString, codecs: 30 * QTBUG-62011: ZWNBS is no longer discarded (mistaken for a BOM despite 31 not being at the start) when converting UCS4 to QString's UCS2. 32 33 - QLocale: 34 * QTBUG-80459: Skip digit-grouping if the system locale is configured to 35 use an empty group separator. 36 * QTBUG-81530: Use "+" if MS reports empty for the system locale's plus 37 sign, as documented in MS's API for the relevant query. 38 39 - QLockFile: 40 * Suppressed the warning on QNX that said 'setNativeLocks failed: 41 "Function not implemented"'. There is no difference in behavior: Qt 42 will continue not to be able to apply an OS- level file lock, which 43 means the lock could be accidentally stolen by buggy software. Correct 44 software using QLockFile should not be affected. 45 46 - QObject: 47 * For the purposes of QT_NO_NARROWING_CONVERSIONS_IN_CONNECT, pointer 48 (incl. pointer-to-member) to bool conversions are now considered 49 narrowing. This matches the resolution of a defect report in C++ 50 itself. 51 52 - QStorageInfo: 53 * Improved discovery of device nodes on Linux if the /dev entry was 54 renamed after the filesystem was mounted and udev is in use. 55 56**************************************************************************** 57* QtGui * 58**************************************************************************** 59 60 - QTextMarkdownImporter: 61 * Text in Markdown format is assumed to be UTF-8. 62 * The "title" in a Markdown hyperlink is now used as the tooltip, 63 not the anchor name. 64 * Fixed vulnerability oss-fuzz-20450 (invalid input resulted in an 65 attempt to insert items into a list that no longer exists). 66 67**************************************************************************** 68* QtWidgets * 69**************************************************************************** 70 71 - QLineEdit: 72 * the inputMask property has allowed any Letter or Number category 73 character for the respective mask characters, not just ASCII. The 74 documentation has been updated accordingly. 75 76**************************************************************************** 77* qmake * 78**************************************************************************** 79 80 - To remove the NDEBUG define that is added by default in MSVC mkspecs, 81 write DEFINES_RELEASE -= NDEBUG in your .pro file. 82 - Install/uninstall rules are now generated for target.targets on Windows. 83 This mirrors the behavior on Unix. 84 85**************************************************************************** 86* Third-Party Code * 87**************************************************************************** 88 89 - md4c was updated to 0.4.3. This fixes vulnerability oss-fuzz-20580. 90 91 - QtSQL, sqlite: 92 * Updated to v3.31.1 93 * [QTBUG-82533] Fixed CVE-2020-9327 94 95**************************************************************************** 96* CMake * 97**************************************************************************** 98 99 - Windows: 100 * Fixed linking with Qt static build 101 102**************************************************************************** 103* MSVC * 104**************************************************************************** 105 106 - Fixed a compatibility issue found when linking code compiled with 107 version 16.6 to a Qt compiled with 16.5. 108 109**************************************************************************** 110* MinGW * 111**************************************************************************** 112 113 - Fixed build regressions. 114 - The -debug-and-release configuration has been fixed. In this 115 configuration, Qt libraries again have a 'd' suffix. 116 - In the -debug configuration, libraries do not have a 'd' suffix, similar 117 to Unix platforms. 118
