- ida.cfg: MangleChars and SubstChar are introduced to allow the creation of mangled names. You are now free to define names containing unusual characters such as “%()” which are used in C++ mangled names but are prohibited in normal identifiers.

- 8051 @dptr addressing mode was lost. This has been corrected.
- 68xx jmp and jsr instructions generated data reference. This has been corrected.
- COFF: the entry point was not properly calculated for some executables. This situation has been corrected.
- In some cases, instructions disappeared from the disassembly if the previous instruction had a fixup information and was analysed at load time. This occured rarely.
- PE files: sometimes the .idata section contains import definitions and additional data. IDA only kept import definitions. IDA’s behaviour can now be controlled through the “load file” dialog box and IDA checks that no useful information is discarded.
