Highlights for R16B01:
OTP-10279 == erts ==
Support for migration of memory carriers between memory
allocator instances has been introduced.
By default this feature is not enabled and do not effect the
characteristics of the system. When enabled it has the
following impact on the characteristics of the system:
-- Reduced memory footprint when the memory load is unevenly
distributed between scheduler specific allocator instances.
-- Depending on the default allocaton strategy used on a
specific allocator there might or might not be a slight
performance loss.
-- When enabled on the fix_alloc allocator, a different
strategy for management of fix blocks will be used.
-- The information returned from
erlang:system_info({allocator, A}), and
erlang:system_info({allocator_sizes, A}) will be slightly
different when this feature has been enabled. An mbcs_pool
tuple will be present giving information about abandoned
carriers, and in the fix_alloc case no fix_types tuple will
be present.
For more information, see the documentation of the +M<S>acul
command line argument.

Integrate elliptic curve contribution from Andreas Schultz
In order to be able to support elliptic curve cipher suites
in SSL/TLS, additions to handle elliptic curve infrastructure
has been added to public_key and crypto.
This also has resulted in a rewrite of the crypto API to gain
consistency and remove unnecessary overhead. All OTP
applications using crypto has been updated to use the new
API.
Impact: Elliptic curve cryptography (ECC) offers equivalent
security with smaller key sizes than other public key
algorithms. Smaller key sizes result in savings for power,
memory, bandwidth, and computational cost that make ECC
especially attractive for constrained environments.
