Windows 2003 and Windows XP pre SP3 would sometimes not
55+
start the Erlang R14B VM at all due to a bug in the cpu
56+
topology detection. The bug affects Windows only, no
57+
other platform is even remotely affected. The bug is now
58+
corrected.</p>

The HiPE run-time in the 64-bit emulator could do a
65+
64-bit write to a 32-bit struct field. It happened to be
66+
harmless on Intel/AMD processors. Corrected. (Thanks to

75+
and <seealso
76+
marker="erl_nif#enif_tsd_get">enif_tsd_get()</seealso>
77+
could cause an emulator crash. These functions are
78+
currently not used in OTP. That is, the crash only occur
79+
on systems with user implemented NIF libraries, or
80+
drivers that use one of these functions.</p>

The ERTS internal rwlock implementation could get into an
97+
inconsistent state. This bug was very seldom triggered,
98+
but could be during heavy contention. The bug was
99+
introduced in R14B (erts-5.8.1).</p>
100+
<p>
101+
The bug was most likely to be triggered when using the
102+
<c>read_concurrency</c> option on an ETS table that was
103+
frequently accessed from multiple processes doing lots of
104+
writes and reads. That is, in a situation where you
105+
typically don't want to use the <c>read_concurrency</c>
106+
option in the first place.</p>

Name resolving of IPv6 addresses has been implemented for
150+
Windows versions that support it. The use of ancient
151+
resolver flags (AI_V4MAPPED | AI_ADDRCONFIG) to the
152+
getaddrinfo() function has been removed since e.g FreeBSD
153+
regard mapped IPv4 addresses to be a security problem and
154+
the semantics of the address configured flag is
155+
uncertain.</p>

of keyboard input. (Thanks to Ryan Tilder.)</p>

The Erlang VM now supports Unicode filenames. The feature
193+
is turned on by default on systems where Unicode
194+
filenames are mandatory (Windows and MacOSX), but can be
195+
enabled on other systems with the '+fnu' emulator option.
196+
Enabling the Unicode filename feature on systems where it
197+
is not default is however considered experimental and not
198+
to be used for production. Together with the Unicode file
199+
name support, the concept of "raw filenames" is
200+
introduced, which means filenames provided without
201+
implicit unicode encoding translation. Raw filenames are
202+
provided as binaries, not lists. For further information,
203+
see stdlib users guide and the chapter about using
204+
Unicode in Erlang. Also see the file module manual page.</p>

The runtime system is now less eager to suspend processes
221+
sending messages over the distribution. The default value
222+
of the distribution buffer busy limit has also been
223+
increased from 128 KB to 1 MB. This in order to improve
224+
throughput.</p>

inet:getiflist/0 and inet:ifget/2.</p>
