The patch releases thus far are early test previews for those who are interested and perhaps willing to play around with. So in short, it's not production quality and not ready for committing to mainline. I'll continue to announce these patches on the mailing list for the time being. I'm of course open to feedback/suggestions/questions and will provide documentation with each release. cheers, nigel >> >> On 11/07/14 16:50, Nigel Williams wrote: >>> Hello all, >>> >>> A new v0.4 patch is available at [1].
