[0.8.0] - 2019-01-06

This is a release to aid packaging. bpftrace has not reached a 1.0 release status yet, as there are still development changes and things to fix. But what is here should be tremendously useful, provided you bear in mind that there will be some changes made to the programming language and command line options between now and a 1.0 release, so any tools or documentation written will become out of date and require changes. If you are anxiously waiting a 1.0 release, please consider contributing so that it can be released sooner.
