+ - [QTBUG-87583] Allowed loading SVG files with a doctype declaration
+ - [oss-fuzz-24611] Implemented a basic format check for compressed svgs so
+   it will fail early if the file does not start with a svg or xml tag after
+   decompressing
+ - [oss-fuzz-24611] Avoids recursion when inflating compressed svgs and no
+   longer returns a partially extracted QByteArray
+ - [oss-fuzz-24347] Reduced memory consumption significantly for huge files.
+ - [oss-fuzz-24735] Reject corrupt svgs with invalid size
