The Asterisk Development Team has released the latest Asterisk version 1.4.14. This is a regular maintenance release that contains numerous bug fixes across the entire code base. A ChangeLog that lists all changes that were made is available with the release.
The release is available on downloads.digium.com. It is also available as a patch against the previous release.
A special note from ChangeLog that I found to be very importent;
Apparent time changes due to daylight savings time are just that, apparent. The use of daylight savings time in a Linux system is purely a user interface issue and does not affect the operation of the Linux kernel or Asterisk. The system clock on Linux kernels operates on UTC. UTC does not use daylight savings time.
Also note that this issue is separate from the clocking of TDM channels, and is known to at least affect SIP registrations.
