Release version 0.20.1

• feat(grok): Bring your own Grok endpoint. Grok Build settings gain a "Custom model (BYO endpoint)" section — point it at any Grok-compatible endpoint with your own model id, base URL, API key, backend, context window, and session auto-compact threshold. Leave the URL blank to fall back to xAI's official endpoint.
• feat(grok): Grok no longer updates itself in the background. The Grok CLI launches with its self-updater disabled, so it keeps running the pinned build instead of silently swapping to a newer one — and its interactive approval prompt stays intact unless you've switched to always-approve.
• feat(grok): The context-window meter now works for Grok sessions. Grok conversations show how much of the model's context window you've used, with the window sized per Grok model (from 256K up to 2M) and paired with Grok's running token count — just like every other agent.
• fix(icon): Monochrome agent icons no longer look dimmed. The OpenCode, Hermes, Grok, Cline, and CodeBuddy marks now render at full strength in the agent selector, sidebar, and status bar, instead of appearing faint until you hover over or select them.
• chore(agents): Bundled agents refreshed. CodeBuddy Code (2.118.2) and Kimi Code (0.23.5) were bumped to their latest builds.

发布版本 0.20.1

• 功能(Grok)：接入你自己的 Grok 端点。 Grok Build 设置新增「自定义模型（BYO 端点）」区域——用你自己的模型 id、base URL、API Key、后端、上下文窗口与会话自动压缩阈值，将 Grok 指向任意兼容的自定义端点；URL 留空则回落到 xAI 官方端点。
• 功能(Grok)：Grok 不再在后台自行更新。 Grok CLI 会以禁用自更新的方式启动，因此它始终运行固定的构建，而不会在后台悄悄换成新版本——其交互式审批提示也照常保留，除非你已切换到「始终批准」。
• 功能(Grok)：上下文窗口计量器现已支持 Grok 会话。 Grok 对话会显示你已用去的上下文窗口比例，窗口大小按各 Grok 模型自动推断（从 256K 到 2M），并与 Grok 的累计 token 数配对显示——与其它智能体完全一致。
• 修复(图标)：单色智能体图标不再显得暗淡。 OpenCode、Hermes、Grok、Cline、CodeBuddy 的图标现在在智能体选择器、侧边栏和状态栏中以全强度渲染，不再要等到悬停或选中时才变清晰。
• 更新(智能体)：内置智能体已刷新。 CodeBuddy Code（2.118.2）和 Kimi Code（0.23.5）升级到最新构建。
