> The change of this release is:
> Fix build error with Linux Kernel 3.0.x version. Thanks for report

> Make getgtprsp.pl support all special trace state variables.
> Fix the bug that set the id of FID_PAGE_BEGIN inside gtp_rb.
> Change code to ignore the task that read the
> /sys/kernel/debug/gtpframe_pipe in default. ?And add special trace
> state variable $pipe_trace to control it.
> Fix error of doc about $ignore_error.
> Add $current_task_pid to access to get_current()->pid.
> Remove GTP_VAR_NOT_GETV, GTP_VAR_NOT_SETV and GTP_VAR_NOT_TRACEV.
> Fix bug in gtp_frame_file_header that affect stack when src of
> conditon or action is bigger than 200.
> To get other change info please goto https://code.google.com/p/kgtp/wiki/UPDATE

> According to the comments of Christoph. ?I make a patch for Linux
