+ Add '-callback' attributes in stdlib's behaviours</p>
+ <p>
+ Replace the behaviour_info(callbacks) export in stdlib's
+ behaviours with -callback' attributes for all the
+ callbacks. Update the documentation with information on
+ the callback attribute Automatically generate
+ 'behaviour_info' function from '-callback' attributes</p>
+ <p>
+ 'behaviour_info(callbacks)' is a special function that is
+ defined in a module which describes a behaviour and
+ returns a list of its callbacks.</p>
+ <p>
+ This function is now automatically generated using the
+ '-callback' specs. An error is returned by lint if user
+ defines both '-callback' attributes and the
+ behaviour_info/1 function. If no type info is needed for
+ a callback use a generic spec for it. Add '-callback'
+ attribute to language syntax</p>
+ <p>
+ Behaviours may define specs for their callbacks using the
+ familiar spec syntax, replacing the '-spec' keyword with
+ '-callback'. Simple lint checks are performed to ensure
+ that no callbacks are defined twice and all types
+ referred are declared.</p>
+ <p>
+ These attributes can be then used by tools to provide
+ documentation to the behaviour or find discrepancies in
+ the callback definitions in the callback module.</p>
+ <p>
+ Add callback specs into 'application' module in kernel
+ Add callback specs to tftp module following internet
+ documentation Add callback specs to inets_service module
+ following possibly deprecated comments</p>

+ <p>
+ The calculation of the 'uniq' value for a fun (see
+ <c>erlang:fun_info/1</c>) was too weak and has been
+ strengthened. It used to be based on the only the code
+ for the fun body, but it is now based on the MD5 of the
+ BEAM code for the module.</p>

+ <p>Variables are now now allowed in '<c>fun M:F/A</c>' as
+ suggested by Richard O'Keefe in EEP-23.</p>
+ <p>The representation of '<c>fun M:F/A</c>' in the
+ abstract format has been changed in an incompatible way.
+ Tools that directly read or manipulate the abstract
+ format (such as parse transforms) may need to be updated.
+ The compiler can handle both the new and the old format
+ (i.e. extracting the abstract format from a pre-R15 BEAM
+ file and compiling it using compile:forms/1,2 will work).
+ The <c>syntax_tools</c> application can also handle both
+ formats.</p>
+ <p>
+ *** POTENTIAL INCOMPATIBILITY ***</p>
+ <p>
+ Own Id: OTP-9643</p>
+ </item>
+ <item>
+ <p>
+ <c>filename:find_src/1,2</c> will now work on stripped
+ BEAM files (reported by Per Hedeland). The HiPE compiler
+ will also work on stripped BEAM files. The BEAM compiler
+ will no longer include compilation options given in the
+ source code itself in <c>M:module_info(compile)</c>
+ (because those options will be applied anyway if the
+ module is re-compiled).</p>
+ <p>
+ Own Id: OTP-9752</p>
+ </item>

+ <p>Inlining binary matching could cause an internal
+ compiler error. (Thanks to Rene Kijewski for reporting
+ this bug.)</p>
