+## 0.7.8 - 2026-10-24

+### English

+- Access page: rename nav to Access & try / 接入与调试, and split into Chat (single-turn streaming) and Native API (playground + curl) tabs with shared account, model, and Base URL.
+- Providers catalog: keep「自定义」reasoning controls from stretching desktop table columns, and stack label + select on mobile cards.
+- Align Qoder Cosy fingerprint with hub v1.7.3: CLI 1.1.75, desktop Cosy-Version 0.4.8, undici User-Agent, business/scene/clientip headers, lowercase `agree` data-policy; machineos on all COSY requests, hostname SSE-only.
+- Bump Codex outbound cloaking User-Agent to official stable `0.164.0`.
+- Pass through inbound `X-Codex-Turn-Metadata`, `X-Codex-Turn-State`, and `X-Codex-Window-Id` on Codex OAuth (non-SIWC) upstream requests, matching CLIProxyAPI’s narrow EnsureHeader set.

+- 接入页：侧栏改名为「接入与调试」，拆成「对话」（单轮流式）与「原生 API」（调试台 + curl）两个页签，账号、模型和 Base URL 共用。
+- 模型目录：自定义推理强度控件不再撑宽桌面表格列；移动端卡片改为标签在上、选择器独占一行。
+- Qoder Cosy 指纹对齐 hub v1.7.3：CLI 1.1.75、桌面签到 Cosy-Version 0.4.8、undici User-Agent、business/scene/clientip 头、data-policy 小写 `agree`；machineos 全 COSY 请求携带，hostname 仅 SSE。
+- Codex 出站伪装 User-Agent 升至官方稳定版 `0.164.0`。
+- Codex OAuth（非 SIWC）上游透传入站 `X-Codex-Turn-Metadata` / `X-Codex-Turn-State` / `X-Codex-Window-Id`，范围与 CLIProxyAPI EnsureHeader 一致、不扩大。
