+ <p><c>erl_tar</c> can now handle files names that contain
+ Unicode characters. See "UNICODE SUPPORT" in the
+ documentation for <c>erl_tar</c>.</p>
+ <p>When creating a tar file, <c>erl_tar</c> would
+ sometime write a too short end of tape marker. GNU tar
+ would correctly extract files from such tar file, but
+ would complain about "A lone zero block at...".</p>

+ <p>The following native functions now bump an appropriate
+ amount of reductions and yield when out of
+ reductions:</p> <list>
+ <item><c>erlang:binary_to_list/1</c></item>
+ <item><c>erlang:binary_to_list/3</c></item>
+ <item><c>erlang:bitstring_to_list/1</c></item>

+ <item><c>erlang:list_to_bitstring/1</c></item>
+ <item><c>binary:list_to_bin/1</c></item> </list>
+ <p>Characteristics impact:</p> <taglist>
+ <tag>Performance</tag> <item>The functions converting
+ from lists got a performance loss for very small lists,
+ and a performance gain for very large lists.</item>
+ <tag>Priority</tag> <item>Previously a process executing
+ one of these functions effectively got an unfair priority
+ boost. This priority boost depended on the input size.
+ The larger the input was, the larger the priority boost
+ got. This unfair priority boost is now lost. </item>
+ </taglist>

+ Own Id: OTP-11888</p>

+ <item>
+ <p>
+ Add <c>maps:get/3</c> to maps module. The function will
+ return the supplied default value if the key does not
+ exist in the map.</p>
