+ <item>
+ <p> The default value <c>undefined</c> was added to
+ records field types in such a way that the result was not
+ always a well-formed type. This bug has been fixed. </p>

+ <p>
+ Update index file atomically</p>
+ <p>
+ Since the log_mf_h index file might be read by other
+ processes than the error handler (e.g. by the rb tool),
+ this file should be updated atomically. This will avoid
+ hitting the time gap between opening the file in write
+ mode (and thus emptying the file) and the actual update
+ with the new contents. To do this, a temporary file is
+ written, and the file:rename/1 used to replace the real
+ index file.</p>

+ <p>
+ Supervisors should not save child-specs for temporary
+ processes when they terminate as they should not be
+ restarted. Saving the temporary child spec will result in
+ that you can not start a new temporary process with the
+ same child spec as an already terminated temporary
+ process. Since R14B02 you can not restart a temporary
+ temporary process as arguments are no longer saved, it
+ has however always been semantically incorrect to restart
+ a temporary process. Thanks to Filipe David Manana for
+ reporting this and suggesting a solution.</p>

+ Fix format_status bug for unregistered gen_event
+ processes</p>
+ <p>
+ Port the gen_fsm code for format_status to gen_event in
+ order to prevent a lists:concat([...,pid()]) crash when
+ calling sys:get_status/1 on an unregistered gen_event
+ process.</p>
+ <p>
+ Refactor format_status header code from gen_* behaviours
+ to module gen.</p>
+ <p>
+ Extend the format_status tests in gen_event_SUITE to
+ cover format_status bugs with anonymous gen_event
+ processes. (Thanks To Geoff Cant)</p>

+ List of pids changed to 'set' in supervisor for dynamic
+ temporary children. Accessing the list would not scale
+ well when adding/deleting many children. (Thanks to
+ Evgeniy Khramtsov)</p>

+ <p>
+ Change pool module to attempt to attach to nodes that are
+ already running</p>
+ <p>
+ The pool module prints out an error message and takes no
+ further action for nodes that are already running. This
+ patch changes that behavior so that if the return from
+ slave:start/3 is {already_running, Node} then an attempt
+ to attach to the node is still made. This makes sense
+ because the node has been specified by the user in the
+ .hosts.erlang file indicating a wish for the node to be
+ part of the pool and a manual attach can be successfully
+ made after the pool is started.(Thanks to Kelly
+ McLaughlin)</p>

+ <p>
+ Add <c>timer:tc/1</c> and remove the catch in <c>tc/2</c>
+ and <c>tc/3</c>. The time measuring functions will thus
+ no longer trap exits, errors or throws caused by the
+ measured function.</p>

+ <p>
+ Allow supervisor:terminate_child(SupRef,Pid) for
+ simple_one_for_one supervisors</p>
+ <p>
+ supervisor:terminate_child/2 was earlier not allowed if
+ the supervisor used restart strategy simple_one_for_one.
+ This is now changed so that children of this type of
+ supervisors can be terminated by specifying the child's
+ Pid.</p>

+ <p> A specification that could cause problems for
+ Dialyzer has been fixed. An opaque type in erl_eval has
+ been turned in to a ordinary type. This is a temporary
+ fix. </p>
