GA Release plans

We were planning on a full GA release in the next month. We have decided to push this further out for a number of reasons, including allowing users to try out the windows port and report any issues they might find.


Fix8 on ARMv7

We are also currently working with the developers of FastFlow to fix issues with Fix8 on ARMv7. We hope to have these issues ironed out soon.

*Update*

We are delaying this release for a few more days. We're fixing a couple more bugs just reported and a few other persistent ones (f8c crashing in particular). We'll get this release out ASAP.
