+ specifies that adjacent separator characters do not give
+ any empty strings in the resulting list of tokens.</p>

+ <p>
+ Fix edlin to correctly save text killed with ctrl-u.
+ Prior to this fix, entering text into the Erlang shell
+ and then killing it with ctrl-u followed by yanking it
+ back with ctrl-y would result in the yanked text being
+ the reverse of the original killed text.</p>

+ <p>
+ If a callback function was terminated with exit/1, there
+ would be no stack trace in the ERROR REPORT produced by
+ gen_server. This has been corrected.</p>
+ <p>
+ To keep the backwards compatibility, the actual exit
+ reason for the process is not changed.</p>

+ Supports tar file creation on other media than file
+ systems mounted on the local machine.</p>
+ <p>
+ The <c>erl_tar</c> api is extended with
+ <c>erl_tar:init/3</c> that enables usage of user provided
+ media storage routines. A ssh-specific set of such
+ routines is hidden in the new function
+ <c>ssh_sftp:open_tar/3</c> to simplify creating a tar
+ archive on a remote ssh server.</p>
+ <p>
+ A chunked file reading option is added to
+ <c>erl_tar:add/3,4</c> to save memory on e.g small
+ embedded systems. The size of the slices read from a file
+ in that case can be specified.</p>

+ The type spec of the FormFunc argument to
+ sys:handle_debug/4 was erroneously pointing to dbg_fun().
+ This is now corrected and the new type is format_fun().</p>

+ Behaviors such as gen_fsm and gen_server should always
+ invoke format_status/2 before printing the state to the
+ logs.</p>

+ <p> The documentation of <c>dets:insert_new/2</c> has

+ <p>
+ Printing a term with io_lib:format and control sequence
+ w, precision P and field width F, where F&lt; P would
+ fail in one of the two following ways:</p>
+ <p>
+ 1) If P &lt; printed length of the term, an infinite loop
+ would be entered, consuming all available memory.</p>
+ <p>
+ 2) If P &gt;= printed length of the term, an exception
+ would be raised.</p>
+ <p>
+ These two problems are now corrected.</p>
