- <p>
- Fix issuing with spaces and quoting in the arguments when
- using erlang:open_port spawn_executable on windows. The
- behavior now mimics how unix works. This change implies a
- backwards incompatibility for how spawn_executable works
- on windows.</p>

- All possibly blocking operations in the fd/spawn and
- terminal driver have been converted to non-blocking
- operations. Before this fix it was possible for the VM to
- be blocked for a long time if the entity consuming
- stdout/stderr did not consume it fast enough.</p>

- Ensure hashing of zero is consistent</p>
- <p> Erlang treats positive and negative zero as
- equal:</p>
- <p>
- <c>true = 0.0 =:= 0.0/-1</c></p>
- <p>However, Erlangs hash functions: hash, phash and
- phash2 did not reflect this behaviour. The hash values
- produced by the different hash functions would not be
- identical for positive and negative zero.</p> <p>This
- change ensures that hash value of positive zero is always
- produced regardless of the signedness of the zero float,

- Improved usage of <c>gcc</c>'s builtins for atomic memory
- access. These are used when no other implementation of
- atomic memory operations is available. For example, when
- compiling for ARM when <c>libatomic_ops</c> is not
- available.</p>
- <p>
- The largest improvement will be seen when compiling with
- a <c>gcc</c> with support for the <c>__atomic_*</c>
- builtins (using a <c>gcc</c> of at least version 4.7),
- but also when only the legacy <c>__sync_*</c> builtins
- are available (using a <c>gcc</c> of at least version
- 4.1) an improvement can be seen.</p>

- Scalability improvement for <seealso

- and other functionality that create references. Each
- scheduler now manage its own set of references. By this
- no communication at all is needed when creating
- references.</p>
- <p>
- Previous implementation generated a strictly
- monotonically increasing sequence of references
- corresponding to creation time on the runtime system
- instance. This is <em>not</em> the case with current
- implementation. You can only expect reference to be
- unique. The Erlang/OTP documentation has never mentioned
- anything else but the uniqueness property, so this change
- <em>is</em> fully compatible. The only reason we've
- marked this as a potential incompatibility is since an
- early draft for an Erlang specification mentions strict
- monotonicity as a property.</p>
- <p>
- If you need to create data with a strict monotonicity
- property use <seealso
- marker="erlang#unique_integer/1">erlang:unique_integer([monotonic])</seealso>.
- Do <em>not</em> use the deprecated <seealso

- Optimization of timers internally in the VM. This include
- process timers (<c>receive ... after</c>), port timers
- (<c>driver_set_timer()</c>) as well as BIF timers
- (<c>erlang:send_after()</c>/<c>erlang:start_timer()</c>).</p>
- <p>
- Each scheduler thread now has its own lock-free timer
- service instead of one locked central service. This
- dramatically improves performance of timer management on
- systems with a large amount of schedulers and timers.</p>
- <p>
- The timer service internal data structure has also been
- optimized to be able to handle more timers than before.
- That is, each timer service is by its self able to handle
- more timers without dramatic performance loss than the
- old centralized timer service.</p>
- <p>
- The API of BIF timers has also been extended. Timeout
- values are for example no longer limited to 32-bit
- integers. For more information see the documentation of
