Shame. I'm on the $20/mo Gemini Pro plan because the 5tb of cloud storage and the youtube premium lite were good enough perks, and my coding complexity needs were light enough for me to overlook Claude or Codex. But Antigravity is working better than Jules and it's basically giving me a taste of what I'm missing and it's harder to justify not trying out the competitors.
I do not, however I am curious about Jules support. I didn't know if this was a dead project or not. Seemed really interesting but then I didn't see much development/announcements/discussions around it. Last update from their changelog was as you said 3.1-pro support in March.
