Ubuntu 17.04 is the first daily build version (Zesty Zapus) released!
GuideThe upcoming Ubuntu 17.04 (Zesty Zapus) Operating System officially announced its entry into the development process. The first daily build version image for early adopters and public adopters has been released.
Although Canonical planned to cancel a 32-bit ISO image earlier this year, the images released today are still available for both 64-bit and 32-bit computers. However, the current development phase is just getting started, so there is not much change in the image, it can be considered that it is basically a small Optimization in Ubuntu 16.10.
Currently, the Canonical official release road map for Ubuntu 17.04 is not released, but the final version is expected to be released in late April 2017. In this development process, two Alpha versions and one Beta milestone version will be released, and Final Beta versions will be available for all Ubuntu versions.
