The Asterisk Development Team is pleased to announce the first release in the Asterisk 1.4 series, Asterisk 1.4.0!

As previously announced, this release contains a large number of new features over the 1.2 series; see the CHANGES file in the distribution for the complete list. Before installing this release, be sure to read the UPGRADE.txt file as well, to be aware of changes that were made that will require you to change configuration files or dialplan entries.

Along with Asterisk, Asterisk-Addons, Zaptel and libpri were also released as 1.4.0 versions.

As usual, the release files are available at downloads.digium.com, and have been signed with GPG keys to ensure their authenticity.

The team thanks you for your support of Asterisk; more than half of the new functionality in this release was developed by community members!
