| **************************************************************************** |
| * Qt 5.9.1 Changes * |
| **************************************************************************** |
| |
| Deprecation Notice |
| ------------------ |
| |
| - The following platforms or toolchains are deprecated and will be |
| removed as of Qt 5.11: |
| * Microsoft Visual Studio 2013 |
| |
| Important Behavior Changes |
| -------------------------- |
| |
| - The Q_REQUIRED_RESULT macro now expands to the C++17 attribute |
| [[nodiscard]] if the compiler supports it. Code using this macro needs |
| to pay attention to its placement, as C++ function attributes must come |
| before the declaration, unlike the GCC extension that this macro |
| previously expanded to. |
| |
| Binary Compatibility Note |
| ------------------------- |
| |
| - The variable QOperatingSystemVersion::MacOSHighSierra was added in this |
| release. Code that uses this variable will not run under Qt 5.9.0. If |
| backwards compatibility is desired, use instead |
| QOperatingSystemVersion(QOperatingSystemVersion::MacOS, 10, 13) |
| |
| Third-Party Code |
| ---------------- |
| |
| - Sqlite was updated to version 3.16.2. |
| - Deleted the src/3rdparty/atspi2 directory. |

| in Objective C++ mode. |
| |
| - QHash/QMultiHash: |

| there are multiple values with the same key. |
| |
| - QStorageInfo |
| * [QTBUG-61096] Fixed a hang on certain systems when retrieving |
| information from unresponsive filesystems. |

| through QDataStream, which previously came out invalid after |
| deserialization. |

| |

| |
| - macOS / iOS: |
| * [QTBUG-41978] QCollator now respects the ignorePunctuation property on |
| Apple based platforms correctly. |
| * [QTBUG-61205] Fixed the architecture information in QSysInfo. |
| * QSysInfo and QOperatingSystemVersion now support the newest versions of |
| Apple's operating systems. |
| * [QTBUG-61053] Fixed SSL certificate verification on iOS with Secure |
| Transport back-end. |

| ------------------------ |

| - [QTBUG-61017] Fixed configure hanging upon selecting commercial license. |
| - [QTBUG-61044] Fixed license checker invocation on 32 bit systems. |
| - [MinGW] The gold linker is no longer used. |
| |
| qmake |
| ----- |
| |
| - [QTBUG-42830][Android] INSTALL targets are no longer created for static |
| libraries. |
| - [QTBUG-40825][QTBUG-59457][Unix] Fixed various makespecs to append shared |
| include and library locations only at the end of the search lists. |
| - [QTBUG-52383][Windows] midl and rc are now invoked with /NOLOGO. |
| - [QTBUG-58391][MSVC] MSVC extensions are not disabled any more when |

| - [MinGW] Re-builds of static library projects will now create a new library |
| instead of updating the previously built one. |
