Hi Ronaldo,
We didn’t receive your email about this. Apologies for that — if it’s still relevant, perhaps you could resend?
We’ve been testing the new version carefully as once it’s released people will need to retrain their models to upgrade, which is inconvenient. You can always export your Prodigy annotations and use them to train a spaCy v2.1 model, so it shouldn’t affect your total workflow to be using the current version of Prodigy. You shouldn’t have Prodigy in your production runtime, usually: there’s no reason to be running the annotation from the same environment you’re using to run your models in production.
We should be pushing a new patch release of spaCy today that fixes a couple of bugs. Once that’s out, I think the current build we have of Prodigy could be considered a release candidate. If there are no further problems found we’ll go ahead and make the v1.8 release. However, please do be patient.
