BUGFIX: DOS: IDA could crash after rebasing databases created for DOS .SYS files
BUGFIX: DSCU: "load libname.dylib" context menu item could be unavailable for some valid addresses
BUGFIX: hexrays: 32-bit magic divisions could be incorrectly recognized on arm64 and ppc64
BUGFIX: hexrays: fixed interr 50340
BUGFIX: hexrays: IDA could crash if no type was selected in "Convert to struct *" dialog, but OK was clicked
BUGFIX: hexrays: it was impossible to change the representation of some constants
BUGFIX: hexrays: op_uses_x() was returning false for 'cot_sizeof'
BUGFIX: hexrays: some switch cases would be wrongly printed as unsigned values
BUGFIX: hexrays: UDT return type could cause INTERR and __spoil<...> attribute was not supported for user-defined calls
BUGFIX: hexrays: wrong handling of big register arglocs on BE plaftorm: valid fastcall functions could be erroneously converted to usercall
BUGFIX: IDA could crash when trying to use license borrowing functionality without opening a file first
BUGFIX: IDA could fail with "out of memory" if something was wrong with the list of trusted idbs
BUGFIX: IDAPython could crash at startup on OSX when used with Python 3.6.
BUGFIX: IDAPython: ida_hexrays.cblock_t.insert() was unusable
BUGFIX: IDAPython: ida_kernwin.UI_Hooks.preprocess_action() wouldn't allow inhibiting the action
BUGFIX: IDAPython: ida_nalt.retrieve_input_file_md5() & ida_nalt.retrieve_input_file_sha256() were returning invalid data
BUGFIX: IDAPython: inspect.stack() could fail on recent versions of Python3 (e.g., Python 3.7.4)
BUGFIX: IDAPython: re-instantiating a chooser a second time could cause some context menu items to appear twice
BUGFIX: IDAPython: when returning an inappropriate type for ida_kernwin.Chooser2.OnGetLine() (e.g., returning a 'map()' in Python3, which produces a map iterable object and not a list), we would receive a cryptic message.
BUGFIX: installer: Python 2.7 installation could fail if path to temp directory contained non-latin characters.
BUGFIX: Lumina: IDA could submit the "File Name:" comment at the beginning of the IDB, as part of the first function's comments.
BUGFIX: M16C: ADD.L #imm, SP instructions could update SP with wrong value
BUGFIX: M16C: added missing DIV?.L and MUL?.L M32C instructions
BUGFIX: pc: sysret was not marked as an instruction that stops execution
BUGFIX: PPC: some VLE switches were not recognized if they used a register other than r0 for loading jump table elements
BUGFIX: Pressing F5 could cause a confusing "conflicting shortcuts" message to be printed in some situations
BUGFIX: ui/qt: it was impossible to change the font for the new type editor
BUGFIX: ui/qt: navigating some forms containing a text area using <Tab> and <Shift+Tab>, was broken
BUGFIX: ui/qt: the "Output window" was not understanding the 'r' (carriage return) character, making Python's 'tqdm' unusable
BUGFIX: UI: it was impossible to add the same file in "Recent scripts" in two IDA instances running simultaneously
BUGFIX: UI: IDA's UI could be sluggish on OSX when using an external display.
BUGFIX: UI: list of patched bytes would be empty when patching a rebased program
BUGFIX: ui: the script snippets could fail highlighting properly when Unicode was involved
