  • BUGFIX: decompiler: fix interrs when decompiling functions with >64 arguments

  • BUGFIX: decompiler: fixed infinite loop while analyzing some golang binaries

  • BUGFIX: decompiler: fixed multiple interrs

  • BUGFIX: disassembly: parentheses could be missing in complex offset expressions like "target-(base+N)"

  • BUGFIX: golang: fixed an interr caused by slice types with circular dependencies

  • BUGFIX: golang: remove unnecessary BUILTIN_SLICE type

  • BUGFIX: idaclang would fail to store mangled symbols in the TIL, which means the prototypes would not be detected when loading the TIL with the "Load type library" action)

  • BUGFIX: idapython: IDA could crash if None was passed to some API calls

  • BUGFIX: kernel: fixed interr 1007 that could occur when processing types with bitfields

  • BUGFIX: kernel: get_item_size(BADADDR) could return huge values in some situations (should be 1)

  • BUGFIX: UI: on Windows, IDA could produce a fatal error "CreateDIBSection failed" when trying to display a very wide hint
