+
+ Users can now configure ETS tables with the
+ {write_concurrency, auto} option. This option forces
+ tables to automatically change the number of locks that
+ are used at run-time depending on how much concurrency
+ is detected. The {decentralized_counters, true} option
+ is enabled by default when {write_concurrency, auto} is
+ active.
+
+ Benchmark results comparing this option with the other
+ ETS optimization options are available here:

+
+ The signal queue of a process with
+ message_queue_data=off_heap* has been optimized to
+ allow parallel reception of signals from multiple
+ processes.
+
+ This is possible to do as Erlang only guarantees that
+ signals (i.e., message signals and non-message signals)
+ sent from a single process to another process are
+ ordered in send order. However, there are no ordering
+ guarantees for signals sent from different processes to
+ a particular process. Therefore, several processes can
+ send signals in parallel to a specific process without
+ synchronizing with each other. However, such signal
+ sending was previously always serialized as the senders
+ had to acquire the lock for the outer signal queue of
+ the receiving process. This parallel signal sending
+ optimization yields much better scalability for signal
+ sending than what was previously possible, see
+ https://erlang.org/bench/sigq_bench_result.html for
+ benchmark results.
+
+ * Information about how to enable the
+ message_queue_data=off_heap setting can be found in the
+ documentation of the function erlang:process_flag/2.

+
+ The format_status/2 callback for gen_server, gen_statem
+ and gen_event has been deprecated in favor of the new
+ format_status/1 callback.
+
+ The new callback adds the possibility to limit and

+
+ A new DEVELOPMENT how-to guide has been added that

+ bugs or developing new functionality.
+
+ The makefile system has been extended to make it easier
+ to run tests at different granulates directly from the
+ command line. This new functionality is described in
+ the development how-to.
+
+ Using the extended makefile system, testing has been

+ *** POTENTIAL INCOMPATIBILITY ***
+
+ As of OTP 25, global will by default prevent
+ overlapping partitions due to network issues by
+ actively disconnecting from nodes that reports that
+ they have lost connections to other nodes. This will
+ cause fully connected partitions to form instead of
+ leaving the network in a state with overlapping
+ partitions.
+
+ Prevention of overlapping partitions can be disabled
+ using the prevent_overlapping_partitions kernel(6)
+ parameter, making global behave like it used to do.
+ This is, however, problematic for all applications
+ expecting a fully connected network to be provided,
+ such as for example mnesia, but also for global itself.
+ A network of overlapping partitions might cause the
+ internal state of global to become inconsistent. Such
+ an inconsistency can remain even after such partitions
+ have been brought together to form a fully connected
+ network again. The effect on other applications that
+ expects that a fully connected network is maintained
+ may vary, but they might misbehave in very subtle hard
+ to detect ways during such a partitioning. Since you
+ might get hard to detect issues without this fix, you
+ are strongly advised not to disable this fix. Also note
+ that this fix has to be enabled on all nodes in the
+ network in order to work properly.
+
+
+ OTP-17953 Application(s): stdlib
+ Related Id(s): PR-5621
+
+ Added filelib:ensure_path/1 that ensures that all

+ The functions uniq/1 and uniq/2 for removing duplicates
+ have been added to the lists module.
+
+
+ OTP-17988 Application(s): compiler, kernel, stdlib, syntax_tools
+
+ Added support for configurable features as described in
+ EEP-60. Features can be enabled/disabled during
+ compilation with options (-enable-feature Feature,
+ -disable-feature Feature and +{feature, Feature,
+ enable|disable}) to erlc as well as with directives
+ (-feature(Feature, enable|disable).) in the file.
+ Similar options can be used to erl for
+ enabling/disabling features allowed at runtime. The new
+ maybe expression (EEP-49) is fully supported as the
+ feature maybe_expr. The features support is documented
+ in the reference manual.
+
+
+ OTP-18011 Application(s): stdlib
+
+ A new PRNG have been added to the rand module: mwc59
+ which has been developed in collaboration with
+ Sebastiano Vigna. It is intended for applications that
+ need really fast pseudo-random numbers, and it comes
+ with two output value scramblers, one fast and one
+ thorough.
+
+ Two internal functions for the exsp generator have also
+ been exported so they can be used outside the rand
+ plug-in framework to shave off some overhead.
+
+ The internal splitmix64 generator has also been
+ exported which can be useful for seeding other kinds of
+ PRNG:s than its own.

+
+ Although OpenSSL 3.0.x itself is stable, its usage in

+
+ As an example, if record #r{} is defined to have only

+ *** HIGHLIGHT ***
+
+ The signal queue of a process with
+ message_queue_data=off_heap* has been optimized to
+ allow parallel reception of signals from multiple
+ processes.
+
+ This is possible to do as Erlang only guarantees that
+ signals (i.e., message signals and non-message signals)
+ sent from a single process to another process are
+ ordered in send order. However, there are no ordering
+ guarantees for signals sent from different processes to
+ a particular process. Therefore, several processes can
+ send signals in parallel to a specific process without
+ synchronizing with each other. However, such signal
+ sending was previously always serialized as the senders
+ had to acquire the lock for the outer signal queue of
+ the receiving process. This parallel signal sending
+ optimization yields much better scalability for signal
+ sending than what was previously possible, see
+ https://erlang.org/bench/sigq_bench_result.html for
+ benchmark results.
+
+ * Information about how to enable the
+ message_queue_data=off_heap setting can be found in the
+ documentation of the function erlang:process_flag/2.

+ As of OTP 25, global will by default prevent
+ overlapping partitions due to network issues by
+ actively disconnecting from nodes that reports that
+ they have lost connections to other nodes. This will
+ cause fully connected partitions to form instead of
+ leaving the network in a state with overlapping
+ partitions.
+
+ Prevention of overlapping partitions can be disabled
+ using the prevent_overlapping_partitions kernel(6)
+ parameter, making global behave like it used to do.
+ This is, however, problematic for all applications
+ expecting a fully connected network to be provided,

+ A network of overlapping partitions might cause the
+ internal state of global to become inconsistent. Such
+ an inconsistency can remain even after such partitions
+ have been brought together to form a fully connected

+ expects that a fully connected network is maintained
+ may vary, but they might misbehave in very subtle hard
+ to detect ways during such a partitioning. Since you
+ might get hard to detect issues without this fix, you

+ Added filelib:ensure_path/1 that ensures that all
+ directories for the given path exists (unlike
+ filelib:ensure_dir/1, which will not create the last

+ Added support for configurable features as described in
+ EEP-60. Features can be enabled/disabled during

+ -disable-feature Feature and +{feature, Feature,
+ enable|disable}) to erlc as well as with directives
+ (-feature(Feature, enable|disable).) in the file.
+ Similar options can be used to erl for
+ enabling/disabling features allowed at runtime. The new

+
+ *** HIGHLIGHT ***
+
+ A new PRNG have been added to the rand module: mwc59
+ which has been developed in collaboration with
+ Sebastiano Vigna. It is intended for applications that
+ need really fast pseudo-random numbers, and it comes
+ with two output value scramblers, one fast and one
+ thorough.
+
+ Two internal functions for the exsp generator have also
+ been exported so they can be used outside the rand
+ plug-in framework to shave off some overhead.
+
+ The internal splitmix64 generator has also been
+ exported which can be useful for seeding other kinds of
+ PRNG:s than its own.
