+Release note  
+============  
+Qt 5.12.11 release is a patch release made on the top of Qt 5.12.10.  
+As a patch release, Qt 5.12.11 does not add any new functionality but provides  
+bug fixes and other improvements and maintains both forward and backward  
+compatibility (source and binary) with Qt 5.12.10.  
+  
+For detailed information about Qt 5.12, refer to the online documentation  
+included in this distribution. The documentation is also available online:  
+  
+  https://doc.qt.io/qt-5.12/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.  
+  
+Some of the changes listed in this file include issue tracking numbers  
+corresponding to tasks in the Qt Bug Tracker:

+Important Changes  
+-----------------  
+  
+### qtbase  
+* f411be7a4a sqlite: Upgrade to 3.33.0  
+Upgraded to v3.33.0  
+  
+* 47a842ee0c Fix included license text for PCRE2 - Stack-less Just-In-  
+Time Compiler  
+Changed license text of "PCRE2 - Stack-less Just-In-Time Compiler"  
+component. The documentation (incorrectly) included the generic PCRE2  
+license so far.  
+  
+* e2c0cc9bb3 Avoid integer overflow and division by zero  
+Pen patterns are restrained to a maximum length and values of 1024,  
+fixing oss-fuzz issue 25310.  
+  
+* 0943ad0241 Containers: call constructors even for primitive types  
+The semantics of Q_PRIMITIVE_TYPE have been slightly changed. Qt now  
+value-initializes types marked as primitive (which, by default, include  
+trivial types) instead of simply using memset(0), which is wrong in some  
+corner cases.  
+  
+* 5d33ae6d94 Update bundled libjpeg-turbo to version 2.0.6  
+libjpeg-turbo was updated to version 2.0.6

+* b2ee9ff3 Client: Fix reverse screen order  
+Fixed a bug where QGuiApplication::screens() and primaryScreen() would  
+return initial screens in the reverse order they were added by the  
+compositor. QGuiApplication::primaryScreen() will now return the first  
+output added by the compositor.  
+  
+* 8fe61d79 Fix leaked subsurface wayland items  
+Fixed a memory leak when creating subsurfaces.  
+  
+### qtimageformats
