OpenEuphoria

If you build from source, you can't just update to the head and expect everything to work, because the front end uses switches. So you'll need to either wait for eubins to be posted, or follow this upgrade path:

1. Update to r1631 and build / install
2. Update to r1634 and build / install

Then you're up to date, as far as switches go, and further updates after that shouldn't be a problem, unless there's some other breaking changes made.
