 This page documents the changes in each Kimi Code CLI release.
 
+## 0.23.1 (2026-07-07)
+
+### Bug Fixes
+
+- Fix `kimi -p` abandoning background subagents that start late or run long, so their results reach the main agent.
+- web: Recover chat streaming after a stale background-tab WebSocket instead of requiring a page refresh.
+- Fix some third-party models (e.g. Opus 4.8) falling back to the family default max output tokens; an unrecognized minor now reuses the nearest earlier known version's limit.
+- Honor explicit Anthropic `max_output_size` settings instead of clamping them to built-in ceilings.
+- Stop showing tool-produced `<system>` metadata in tool outputs; failed tools now show their own error text.
+- Fix goal completion and blocked updates to produce one final user-facing outcome summary from the tool result.
+- Fix goal startup and queue handling so failed starts restore permission mode and queued goals wait behind new user messages.
+- Fix goal token budgets to count model completion tokens and stop without extra continuation steps when the budget is exhausted.
+- Fix goal tools being unavailable to the main agent, and return clear messages for invalid goal-control calls.
+- Respect the `--skills-dir` flag in interactive mode.
+- web: Fix several slash commands and skills not working on the new-session screen: `/goal <objective>` and slash skill activations (for example `/pre-changelog`) silently did nothing, and `/btw [<question>]` opened an empty side chat.
+
+### Polish
+
+- Preserve prior turns' thinking by default on the Anthropic provider (Claude and Kimi's Anthropic-compatible mode), matching the Kimi default. Disable with `[thinking] keep = "off"` or `KIMI_MODEL_THINKING_KEEP=off`.
+- Clarify the permission mode descriptions shown by `/permission`, `/auto`, and `/yolo`, and reorder `/auto` and `/yolo` in the command list.
+- Show long-running goal wall-clock budget reminders in hours.
+- Tighten goal-mode guidance so agents continue reasonable work across turns instead of ending goals prematurely.
+
+### Refactors
+
+- Record a per-request trace in the session wire log, so model requests can be reconstructed for debugging.

 本页记录 Kimi Code CLI 每个版本的变更内容。
 
+## 0.23.1（2026-07-07）
+
+### 修复
+
+- 修复 `kimi -p` 会丢弃启动较晚或运行时间较长的后台子 Agent、导致结果无法返回主 Agent 的问题。
+- web: 修复后台标签页 WebSocket 失效后聊天流中断、必须刷新页面的问题，现在会自动恢复。
+- 修复一些第三方模型如 Opus 4.8 错误回退到系列默认最大输出 token 数的问题，未收录的次要版本现在会沿用最近的已知较早版本的限制。
+- 修复显式设置的 Anthropic `max_output_size` 被裁剪到内置上限的问题，现在会尊重用户配置。
+- 修复工具输出中混入工具产生的 `<system>` 元数据的问题，失败的工具现在会显示其自身的错误信息。
+- 修复目标完成或被阻塞时的更新行为，现在会从工具结果生成一条最终的、面向用户的结果摘要。
+- 修复目标启动失败时未恢复权限模式、以及排队目标未等待新用户消息的问题。
+- 修复目标 token 预算未计入模型补全 token 的问题，预算耗尽时现在会直接停止，不再执行额外的续跑步骤。
+- 修复主 Agent 无法使用目标工具的问题，并为无效的目标控制调用返回清晰的提示信息。
+- 修复交互模式下 `--skills-dir` 选项未生效的问题。
+- web: 修复新会话页面上多个斜杠命令与 Skill 激活无效的问题：`/goal <objective>` 与斜杠 Skill 激活（如 `/pre-changelog`）之前毫无反应，`/btw [<question>]` 会打开一个空的侧聊。
+
+### 优化
+
+- Anthropic 供应商（Claude 与 Kimi 的 Anthropic 兼容模式）现在默认保留历史轮次的思考内容，与 Kimi 默认行为一致；可通过 `[thinking] keep = "off"` 或 `KIMI_MODEL_THINKING_KEEP=off` 关闭。
+- 优化 `/permission`、`/auto`、`/yolo` 显示的权限模式描述，并在命令列表中调整 `/auto` 与 `/yolo` 的顺序。
+- 长时间运行目标的运行时长预算提醒现在以小时为单位显示。
+- 优化目标模式指引，使 Agent 在合理范围内跨轮次继续工作，避免过早结束目标。
+
+### 重构
+
+- 在会话 wire 日志中记录每次请求的追踪信息，以便在调试时还原模型请求。
