+ Properties support. New options connected to PCRE 8.33
+ are also added to the re module (ucd, notempty_atstart,
+ no_start_optimize). PCRE has extended the regular
+ expression syntax between 7.6 and 8.33, why this imposes
+ a potential incompatibility. Only very complicated

+ A call to either the <c>garbage_collect/1</c> BIF or the
+ <c>check_process_code/2</c> BIF may trigger garbage
+ collection of another processes than the process calling
+ the BIF. The previous implementations performed these
+ kinds of garbage collections without considering the
+ internal state of the process being garbage collected. In
+ order to be able to more easily and more efficiently
+ implement yielding native code, these types of garbage
+ collections have been rewritten. A garbage collection
+ like this is now triggered by an asynchronous request
+ signal, the actual garbage collection is performed by the
+ process being garbage collected itself, and finalized by
+ a reply signal to the process issuing the request. Using
+ this approach processes can disable garbage collection
+ and yield without having to set up the heap in a state
+ that can be garbage collected.</p>
+ <p>
+ The <seealso
+ marker="erts:erlang#garbage_collect/2"><c>garbage_collect/2</c></seealso>,
+ and <seealso
+ marker="erts:erlang#check_process_code/3"><c>check_process_code/3</c></seealso>
+ BIFs have been introduced. Both taking an option list as
+ last argument. Using these, one can issue asynchronous
+ requests.</p>
+ <p>
+ <c>code:purge/1</c> and <c>code:soft_purge/1</c> have
+ been rewritten to utilize asynchronous
+ <c>check_process_code</c> requests in order to
+ parallelize work.</p>
+ <p>
+ Characteristics impact: A call to the
+ <c>garbage_collect/1</c> BIF or the
+ <c>check_process_code/2</c> BIF will normally take longer
+ time to complete while the system as a whole wont be as
+ much negatively effected by the operation as before. A

+ associations</c></item> <item><c>M1 = M0#{ a := 10 }, %

+ "hi" := V1, a := V2, b := V3} = M2. % match keys with
+ values</c></item> </taglist></p>
+ <p>
+ For information on how to use Maps please see Map Expressions in the
+ <seealso marker="doc/reference_manual:expressions#map_expressions">
+ Reference Manual</seealso>.</p>

+ The current implementation is without the following
+ features: <taglist> <item>No variable keys</item>
