6. The cross reference tool xref
Check for undefined function calls
With a predefined analyse like this: xref:analyze(s, undefined_function_calls).
Or with a query like this:
xref:q(s, “XC || (XU - X - B)”).
Uses debug information present in each .beam file
Works really fast, analysing the whole Erlang/OTP in less than 1 minute.

xref:start(s).
xref:add_release(s,code:lib_dir(),[{name,otp}]).
xref:q(s, “domain(XC || epp) - epp”). {ok,[{coast_compile_funcs,close_in_and_outfiles,2}, {compile,parse_module,1}, {dbg_icompile,parse_file,1}, {dbg_ui_recedit,parse_file,4}, {exref_cross_ref,xref_file,3}, {make,check_includes,3}]
Find all direct calls to the module epp

9. Trace on local functions
In R6B call tracing was greatly improved,
In R7B also calls to local functions can be traced in the same manner (without the need to trace compile any module)
erlang:trace_pattern/3 and new functions in the dbg module.

10. File operations can now run in a separate thread.
A threaded file driver
File operations can now run in a separate thread.
Threaded file IO not activated as default.
Activated by a flag to the emulator like this: erl -A 3 which sets the number of threads to 3
