I am happy to tell that I have finally finished the 8.2.0 rsyslog release and it is on its way to announcement, package build and so on. While v8 was basically finished since before last christmas, we had a couple of mostly nits holding the release. This is probably a lesson that we need to accept some nits instead of holding a release for so long.
With that said, there is still a nit: it is undecided how the new doc system shall be distributed. In 8.2.0, it will be a tarball inside the main tarball, something that already (and rightfully) drew some criticism. However, this time I have decided to keep on with the release rather than block it again. After all, it's easy to fix this in 8.2.1 if we settle the issue quickly.
With v8 stable released, project policy is to officially stop support for v7. In any case, we'll have a close look at 7.6 and will provide assistance in the next couple of weeks. After all, v8 is a considerable change, even some of the more exotic contributed output modules are not available with it. So there is a good point in keeping support for v7.6 at least until we really see there is no technical reason for keeping it.
I hope that v8 will be well-perceived ... and look forward to hear both success and bug reports.
If you are interested in what are the big changes, please have a look at this slightly older blog post describing what's new in the rsyslog v8 engine.
