 ### 🔧 Bug Fixes
 
@@ -56,16 +60,20 @@
 - **fix(providers):** resolve `opencode/` → `opencode-zen` slug mismatch + add 40+ new models — `opencode` is now a proper alias for `opencode-zen` in executor, model resolver, and provider registry; adds GPT 5.x, Claude 4.x, Gemini 3.x, Grok, Kimi, and other models with tests. ([#2517](https://github.com/diegosouzapw/OmniRoute/pull/2517) — thanks @herjarsa)
 - **fix(antigravity):** fail over stalled Antigravity sessions — new `ANTIGRAVITY_PRE_RESPONSE_TIMEOUT_CODE` shared constant for pre-response timeout detection, automatic failover to next account when session stalls before headers arrive. Node.js engine range relaxed to `>=20.20.2`. ([#2464](https://github.com/diegosouzapw/OmniRoute/pull/2464) — thanks @dhaern)
 - **fix(deepseek-web):** fix SSE parser, prompt format, and error handling — handles all 3 DeepSeek SSE stream formats (initial fragments, APPEND operations, bare string tokens), simplifies prompt to single-turn to prevent chat marker leakage, and checks `json.code` before token extraction. ([#2502](https://github.com/diegosouzapw/OmniRoute/pull/2502) — thanks @ovehbe)
+- **fix(codex):** accept `auth.json` without `auth_mode` field on import — Codex CLI no longer writes `auth_mode`; import now accepts both formats as long as required tokens are present. Semantic cache read now requires explicit `temperature: 0`. ([#2536](https://github.com/diegosouzapw/OmniRoute/pull/2536) — thanks @janeza2)
 
 ### 🌐 Internationalization
 
 - **i18n(zh-CN):** translate 830 missing UI strings — replaces all `__MISSING__:` placeholders with proper Chinese translations. ([#2523](https://github.com/diegosouzapw/OmniRoute/pull/2523) — thanks @InkshadeWoods)
 - **i18n(dashboard):** add missing dashboard keys and fix EN fallbacks — hundreds of hardcoded English strings across cache, caveman, costs, skills, memory, and evals pages replaced with `t()` calls. ([#2500](https://github.com/diegosouzapw/OmniRoute/pull/2500) — thanks @Gi99lin)
+- **i18n(pt-BR):** complete and fix Brazilian Portuguese translation — comprehensive overhaul of pt-BR locale with ~3000 lines of quality translations, filling all missing keys and correcting existing entries. ([#2543](https://github.com/diegosouzapw/OmniRoute/pull/2543) — thanks @alltomatos)
 
 ### 📝 Maintenance
 
 - **chore:** remove Akamai VPS deploy from release workflow and skills.
 - **chore:** ignore `.claude/worktrees` from git tracking.
+- **chore(ci):** auto-lock release branch on version publish — new CI workflow applies `lock_branch` protection when a GitHub Release is published. ([#2542](https://github.com/diegosouzapw/OmniRoute/pull/2542))
+- **docs:** redesign README — marketing-first layout with accurate provider counts. ([#2490](https://github.com/diegosouzapw/OmniRoute/pull/2490))
