[asterisk-dev] Asterisk 1.8.7.0-rc1 Now Available

[Asterisk Development Team]

The Asterisk Development Team announces the first release candidate of
Asterisk 1.8.7.0. This release candidate is available for immediate 
download at
http://downloads.asterisk.org/pub/telephony/asterisk/

The release of Asterisk 1.8.7.0-rc1 resolves several issues reported by the
community and would have not been possible without your participation.
Thank you!

Please note that a significant numbers of changes and fixes have gone into
features.c in this release (call parking, built-in transfers, call 
pickup, etc.)
and a testing focus on those particular areas would be appreciated.

Also, a known issue with the iLBC installation script get_ilbc_source.sh 
found
in the contrib/scripts/ sub-directory will be resolved prior to the full 
release
of Asterisk 1.8.7.0.

The following is a sample of the issues resolved in this release candidate:

* Added the 'storesipcause' option to sip.conf to allow the user to 
disable the
   setting of HASH(SIP_CAUSE,<chan name>) on the channel. Having 
chan_sip set
   HASH(SIP_CAUSE,<chan name>) on the channel carries a significant 
performance
   penalty because of the usage of the MASTER_CHANNEL() dialplan function.

   We've decided to disable this feature by default in future 1.8 
versions. This
   would be an unexpected behavior change for anyone depending on that 
SIP_CAUSE
   update in their dialplan. Please refer to the asterisk-dev mailing 
list more
   information:

* Significant fixes and improvements to parking lots.
   (Closes issues ASTERISK-17183, ASTERISK-17870, ASTERISK-17430, 
ASTERISK-17452,
    ASTERISK-17452, ASTERISK-15792. Reported by: David Cabrejos, Remi 
Quezada,
    Philippe Lindheimer, David Woolley, Mat Murdock. Patched by: rmudgett)

* Numerous issues have been reported for deadlocks that are caused by a 
blocking
   read in res_timing_timerfd on a file descriptor that will never be 
written to.
   A change to Asterisk adds some checks to make sure that the timerfd 
is both
   valid and armed before calling read(). Should fix: ASTERISK-18142,
   ASTERISK-18197, ASTERISK-18166 and possibly others.

   (In essence, this change should make res_timing_timerfd usable.)

* Resolve segfault when publishing device states via XMPP and not connected.
   (Closes issue ASTERISK-18078. Reported, patched by: Michael L. Young. 
Tested
    by Jonathan Rose)

* Refresh peer address if DNS unavailable at peer creation.
   (Closes issue ASTERISK-18000)
