Oracle has unveiled Solaris 11.4 CBE (Common Build Environment), a new free variant of the Solaris 11.4 operating system aimed at open source and personal use by developers. Unlike the previously offered major builds of Solaris 11.4, the license for which allows free use for testing, development and use in personal projects, the new edition is distinguished by the use of a continuous model for publishing new versions and is close to the Solaris 11.4 SRU (Support Repository Update) edition.
The use of CBE will make it easier for those who wish to use Solaris for free to access the latest software and updates. In fact, CBE builds can be considered beta builds and are similar to Solaris 11.4 SRU pre-test builds, including newer software versions and cumulative bug fixes available at the time of the release (the CBE build does not include all the fixes offered in a similar SRU build release, as as formed before, but unreleased fixes are cumulative and offered in the next release).
To use CBE, it is suggested to install a regular build of Oracle Solaris 11.4.0, connect the pkg.oracle.com/solaris/release repository to IPS and update it to the CBE version by running the "pkg update" command. Separate iso images are not yet available, but they are promised to be published on the main Solaris download page. Like SRU releases, new CBE builds are expected to be published monthly. The Solaris public components code is available in a GitHub repository, and individual packages can be downloaded from pkg.oracle.com.
