# Changelog v0.3.77 - 2026-05-28

### Fixed
- **OpenCode Zen model catalog sync** — removed 3 models that are no longer free and added 1 new free model:
  - ❌ Removed `qwen3.6-plus-free` — free promotion ended, now requires OpenCode Go subscription or PAYG
  - ❌ Removed `minimax-m2.5-free` — 7-day launch promo expired, now paid
  - ❌ Removed `gpt-5-nano` — was incorrectly cataloged as free, actually requires Zen PAYG
  - ✅ Added `mimo-v2.5-free` — newly confirmed free on Zen
  - Result: Zen free catalog updated from 6 → 4 confirmed free models

### Changed
- Updated README Zen models table to reflect the current 4-model free tier
