I’m pretty sure HB doesn’t actually know what the release date for the EF will be. Maybe they have a "calculated" date that keeps shifting every time a new problem comes up. And when you’re developing a module like that, there are bound to be constant new issues. I understand why they’re staying silent, no matter what they say, people would criticize them anyway. So staying silent is probably the only valid option. If I had to guess, I’d say it’ll take at least another two years from now, but honestly, who knows?
