+ Driver output has been corrected so output of large
+ binaries (> 4 GiB) now does not silently fail or crash
+ the emulator, but either outputs the binary or fails the
+ call. This means that writing a binary > 4 Gib to file
+ now works but on e.g 64-bit Windows (that has
+ scatter/gather I/O buffer segment lengths of 32 bits)
+ fails. The behaviour may change in the future to always
+ write the binary, in parts if necessary.</p>

+ erts: minor fix for unnecessary condition erts: change
+ SENDFILE_CHUNK_SIZE from signed to unsigned (Thanks to

+ <p>If a process calls a module with an running on_load
+ handler, the process is supposed to be suspended. But if
+ the module with the on_load handler was loading used
+ <c>code:load_binary/3</c>, the call would instead fail
+ with an <c>undef</c> exception.</p>

+ File name and error reason is now returned if creation of
+ a cookie fails. (Thanks to Magnus Henoch)</p>

+ Various typographical errors corrected in documentation
+ for the global, error_logger, etop, lists, ets and
+ supervisor modules and in the c_portdriver and kernel_app
+ documentation. (Thanks to Ricardo Catalinas Jim�nez)</p>

+ <item>
+ <p> Fix returned error from gen_tcp:accept/1,2 when
+ running out of ports
+ <p>
+ The {error, enfile} return value is badly misleading and
+ confusing for this case, since the Posix ENFILE errno
+ value has a well-defined meaning that has nothing to do
+ with Erlang ports. The fix changes the return value to
+ {error, system_limit}, which is consistent with e.g.
+ various file(3) functions. inet:format_error/1 has also
+ been updated to support system_limit in the same manner
+ as file:format_error/1. (Thanks to Per Hedeland)</p></p>

+ Own Id: OTP-9990</p>
+ </item>
+ <item>
+ <p><c>erts_debug:size/1</c> has been corrected to take
+ sharing in the environment of funs into account. For funs
+ it used to always give the same result as
+ <c>erts_debug:flat_size/1</c>.</p>

+ In some cases when the process doing file:sendfile
+ crashes while sending the file the efile_drv code would
+ not clean up after itself correctly. This has now been
+ fixed.</p>

+ On BSD based platforms file:sendfile would sometime go
+ into an infinite loop when sending big files. This has
+ now been fixed.</p>

+ <item>
+ <p>While <c>disk_log</c> eagerly collects logged terms
+ for better performance, collecting too much data may
+ choke the system and cause huge binaries to be
+ written.</p>
+ <p>The problem was addressed in OTP-9764, but the
+ situation was not improved in all cases.</p>

+ The documentation of .app files incorrectly said that the
+ default value for the <c>mod</c> parameter is
+ <c>undefined</c>. This is now corrected to <c>[]</c>.</p>
