* \+ golang: apply reflection function prototypes to methods when available
* \+ golang: create function types from reflection metadata
* \+ PDB: support SP-relative local variables
* \+ UI: speed up Home/End/Digits navigation in sorted choosers

**Bugfixes**

* BUGFIX: debugger: IDA could lock up if the remote debug server stopped responding
* 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
* BUGFIX: UI: Options>Compiler>Arguments setting was not saved in the database
