Release Notes: Essential fixes for CVE-2013-2222/2223. Better support for both OpenSSL and GnuTLS. Paranoid mode support. Improved support for mingw builds. Many additional improvements since the 2.0.0 release.
Release Notes: Updated to build using ccrtp 2.x and GNU uCommon 5.x libraries.
Release Notes: Support for building the library using the Android NDK has been added, as well as C wrappers to make it easy to build with pjsip. Fixes for race conditions and better support for multi-stream mode were also added. Updated for the latest inter-operable ZRTP specs. Requires ccrtp 1.7.2 (or later), which fixes an issue with padded SRTP packets.
Release Notes: The library was upgraded for changes in draft 13 of the IETF ZRTP specification.
Release Notes: This release implements the new Key Derivation Function as defined by ZRT spec 12. The protocol identifier has been increased to 1.10.
Release Notes: Compliant with the final (official) version of Zimmermann's ZRTP specification for IETF. Builds successfully with Twinkle softphone client 1.3.2 for enabling ZRTP support.
Release Notes: This version is interoperable with the latest ZRTP draft specification and the latest Zfone beta. The changes resulted in an update of the API, therefore existing applications must be recompiled.
Release Notes: This release implements the ZRTP protocol as described in the current draft "draft-zimmermann-avt-zrtp-06x". GNU ZRTP has been tested to work with Phil Zimmerman's latest public beta of his Zfone project (dated April 2nd, 2008).
Release Notes: The ZRTP implementation is now compliant with the latest ZRTP draft. The new ZRTP packet layout and protocol is now a protocol on its own, completely decoupled from RTP; it just happens to use then same connection. These changes provided for an even better decoupled implementation of ZRTP. The license has been updated to the GPLv3 or later.
