+ Improved dirty scheduler support. A purge of a module can
+ now be performed without having to wait for completion of
+ all ongoing dirty NIF calls.</p>
+ <p>
+ Note that when enabling support for dirty schedulers, a
+ new purge strategy will as of ERTS version 8.1 be
+ enabled. This new strategy is not fully backwards
+ compatible with the strategy used by default. For more
+ information see the documentation of <seealso
+ marker="erts:erlang#check_process_code/3"><c>erlang:check_process_code/3</c></seealso>.</p>

+ <p>
+ A new purge strategy has been introduced. The new
+ strategy will by default be disabled during the OTP 19
+ release, but will be the only strategy available as of
+ the OTP 20 release.</p>
+ <p>
+ The new strategy is slightly incompatible with the
+ strategy being used by default in OTP 19. Using the
+ default strategy, processes holding <c>fun</c>s that
+ refer to the module being purged either fail a soft
+ purge, or will be killed during a hard purge. The new
+ strategy completely ignores <c>fun</c>s. If <c>fun</c>s
+ referring to the code being purged exist, and are used
+ after a purge, an exception will be raised upon usage.
+ That is, the behavior will be exactly the same as the
+ case when a <c>fun</c> is received by a process after the
+ purge.</p>
+ <p>
+ The new strategy can optionally be enabled when building
+ OTP during OTP 19, and will automatically be enabled if
+ the runtime system is built with support for dirty
+ schedulers.</p>
