- Building: Add SHARED variable to Makefile to choose if hashcat is build as static or shared binary (using libhashcat.so/hashcat.dll)
|
||||
- Building: Removed the use of RPATH on linker level
|
||||
- Events: Improved the maximum event message handling. event_log () will now also internally make sure that the message is properly terminated
