Hi,

Thanks for your enquiry. Instant Reverse support up to C++11.

Hi,

Sorry for the delay.  
Instant Reverse C++ rely on Doxygen, it claims to support C++11 only, but I briefly tested it works with C++17 syntax (nested namespace).  
I also briefly tested with Visual Studio 2019 Integration (will be available in next hot fix) code synchronization can works with C++17.

As I know, C++20 specification is not finalize.

Hi,

if VP claims supporting C++11 it should support followin syntax:

virtual ~class\_name() = default;

ans it does not while updating from code:  
[13:24:33] [Error] Unable to read file \*\*\*\*\*\*\*\*\*\*\*\* Parse error at line 10, column 31. Encountered: default

Any chances for a fix ?
