Kazam Screencaster is a mostly abandoned screen recording program. The latest available release is version 1.4.5 released in August 2014. Some distributions, namely Ubuntu, are still shipping it and applying minor fixed to ensure that it keep compiling with newer libraries. Any actual development has stalled.
Kazam Screencaster has a homepage at launchpad.net/kazam where it would be possible to see if someone comes along and re-starts development.
