  • Optional serialization/deserialization of the encoding parameters through the feature serialize
    • Optional cli advanced commands to use it.
  • The builds are now using the dwarf debug format for the targets that support it, before it was a mixture of dwarf and stabs due to the nasm defaults.


  • Segmentation support is now a tunable SpeedSetting and currently it is default off since it can produce desyncs.
