DWARF: The plugin could perform a use-after-free during stack unwinding, on some DWARF input files.DWARF: The plugin could loop (seemingly) endlessly when encountering a DW_TAG_namespace with a (broken) name whose first character is '#'.DWARF: The plugin could cause IDA to crash (stack exhaustion) with some specially crafted input files.DWARF: The DWARF plugin could INTERR with specially crafted files.DWARF: The DWARF plugin could crash IDA (null pointer dereference) with some specially-crafted files.DWARF: IDA could try to allocate too much memory on corrupted files before dying with out-of-memory error.Decompiler: some xrefs to enum members would be missed by Ctrl-Alt-X.Decompiler: renaming a structure field would cause the loss of the _cppobj attribute.Decompiler: PPC: if addresses are subtracted assume that the size is being calculated.Decompiler: on macOS, the decompiler would use shortcut 'Ins' instead of 'I' for the 'Edit block comment' action.Decompiler: jumping to the pseudocode from another window (for example, from the local types) would fail to activate the window in some cases.Decompiler: 'create new struct type' could generate a new struct type with forbidden characters, like myvara).Debugger: xnu debugger would fail to demangle c++ names after attaching with an empty database.Debugger: linux: debugger could interr when handling program with many short-lived threads.Debugger: PIN: get rid of warning 'Unexpected addrsize of the debugged program', permit remote PIN to be started by Debug->Attach.Debugger: mac debugger could fail to load symbols from system dylibs.Debugger: mac/ios/xnu debuggers would create tons of meaningless debugger segments.Debugger: ios debugger could fail to fetch the process list on iOS 14.Debugger: ios debugger was broken on iOS14.

Cloning script snippets could corrupt the database.Chooser: the ui_get_chooser_item_attrs event was called with the wrong CHOOSER argument.A crafted IDB file could trigger a use-after-free in IDA.78K0S: opcode D5 was incorrectly decoded as INC (should be DEC).see BOOT_KC_PATH in macho.cfg for an overview

support symbolication of macOS11 kernelcaches that link against the boot/sys kext collection.

improve handling of threaded pointers in iOS kernelcaches.

We also improved symbolication of MH_FILESET kernelcaches.

We improved macOS11 kernel debugging with VMware Fusion 12.

The Service Pack 3 introduces a handful of new and interesting features specific to the soon-to-be-released macOS 11 (Big Sur) and provides fixes for numerous minor issues.
