+ <item>
+ <p>
+ Several type specifications for standard libraries were
+ wrong in the R14B01 release. This is now corrected. The
+ corrections concern types in re,io,filename and the
+ module erlang itself.</p>

+ <item>
+ <p>The HiPE compiler could crash when compiling certain
+ modules (the bug has been latent, and been exposed by new
+ optimizations introduced in the BEAM compiler in R14A).
+ (Thanks to Mikael Pettersson.)</p>

+ <item>
+ <p><c>receive</c> statements that can only read out a
+ newly created reference are now specially optimized so
+ that it will execute in constant time regardless of the
+ number of messages in the receive queue for the process.
+ That optimization will benefit calls to
+ <c>gen_server:call()</c>. (See <c>gen:do_call/4</c> for
+ an example of a receive statement that will be
+ optimized.)</p>

+ Various changes to dialyzer-related files for R14.</p>
+ <p>
+ - Dialyzer properly supports the new attribute
+ -export_type and checks that remote types only refer to
+ exported types. A warning is produced if some
+ files/applications refer to types defined in modules
+ which are neither in the PLT nor in the analyzed
+ applications.</p>
+ <p>
+ - Support for detecting data races involving whereis/1
+ and unregister/1.</p>
+ <p>
+ - More precise identification of the reason(s) why a
+ record construction violates the types declared for its
+ fields.</p>
+ <p>
+ - Fixed bug in the handling of the 'or' guard.</p>
+ <p>
+ - Better handling of the erlang:element/2 BIF.</p>
+ <p>
+ - Complete handling of Erlang BIFs.</p>
+ <p>
+ Own Id: OTP-8699</p>
+ </item>
+ <item>
+ <p><c>eprof</c> has been reimplemented with support in
+ the Erlang virtual machine and is now both faster (i.e.
+ slows down the code being measured less) and scales much
+ better. In measurements we saw speed-ups compared to the
+ old eprof ranging from 6 times (for sequential code that
+ only uses one scheduler/core) up to 84 times (for
+ parallel code that uses 8 cores).</p>
+ <p>Note: The API for the <c>eprof</c> has been cleaned up
+ and extended. See the documentation.</p>
