+ Using the <c>from_asm</c> option to produce a BEAM file

+ 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>
+ <p>
+ The current implementation is without the following
+ features: <taglist> <item>No variable keys</item>
+ <item>No single value access</item> <item>No map
+ comprehensions</item> </taglist></p>
+ <p>
+ Note that Maps is <em>experimental</em> during OTP 17.0.</p>

+ <p>
+ The default encoding for Erlang source files is now
+ UTF-8. As a temporary measure to ease the transition from
+ the old default of latin-1, if the compiler encounters
+ byte sequences that are not valid UTF-8 sequences, the
+ compiler will re-try the compilation in latin-1 mode.
+ This workaround will be removed in a future release.</p>
