+## [1.6.5] - 2026-03-24
+
+### OpenClaw 3.23 Compatibility
+
+OpenClaw 3.23 introduced strict config validation at CLI startup — any `openclaw` subcommand (including `plugins install`, `plugins update`, `gateway stop`) now validates the entire `openclaw.json` before execution. Since `channels.qqbot` is registered by this plugin (not a built-in channel id), running these commands when the plugin is not yet loaded causes `"Config invalid: unknown channel id: qqbot"` and the command fails entirely (chicken-and-egg problem).
+
+This release adapts all upgrade paths for 3.23+:
+
+- **Config stash/restore for CLI commands**: `upgrade-via-npm.sh` and `upgrade-via-source.sh` temporarily remove `channels.qqbot` from `openclaw.json` before running any openclaw CLI command, then restore it after completion.
+- **Gateway pre-stop before install**: `upgrade-via-source.sh` now stops the gateway before `plugins install` to prevent chokidar from triggering a restart on the intermediate config state (with `channels.qqbot` removed), which would also hit the validation error.
+
+### Fixed
+
+- **Startup greeting marker path**: Fixed marker directory to use `$CMD` variable instead of hardcoded path, supporting multi-CLI environments.
+
+### Changed
+
+- **Silence non-upgrade startup greeting**: Startup greeting is now suppressed unless triggered by a `/bot-upgrade` hot update, reducing noise during routine gateway restarts.

+## [1.6.5] - 2026-03-24
+
+### OpenClaw 3.23 兼容适配
+
+OpenClaw 3.23 在 CLI 启动时引入了严格配置校验——任何 `openclaw` 子命令（包括 `plugins install`、`plugins update`、`gateway stop`）执行前都会校验整个 `openclaw.json`。由于 `channels.qqbot` 是本插件注册的（非内置 channel id），当插件尚未加载时执行这些命令会报 `"Config invalid: unknown channel id: qqbot"` 直接失败（鸡生蛋问题）。
+
+本版本对所有升级路径进行了 3.23+ 适配：
+
+- **CLI 命令前配置暂存/恢复**：`upgrade-via-npm.sh` 和 `upgrade-via-source.sh` 在执行任何 openclaw CLI 命令前临时移除 `channels.qqbot`，完成后恢复。
+- **安装前预停 Gateway**：`upgrade-via-source.sh` 在 `plugins install` 前先停止 gateway，防止 chokidar 在配置中间状态（`channels.qqbot` 已移除）时触发 restart，避免同样的校验错误。
+
+### 修复
+
+- **启动问候 marker 路径**：修复 marker 目录使用 `$CMD` 变量替代硬编码路径，支持多 CLI 环境。
+
+### 变更
+
+- **静默非升级启动问候**：启动问候仅在 `/bot-upgrade` 热更新触发时发送，常规 gateway 重启不再发送，减少消息干扰。
+

-# qqbot 测试脚本：自由切换不同的 QQBot npm 包
-#
-# 支持从任意 npm 包安装指定版本到 openclaw extensions 目录。
-# 可用于在不同包之间切换测试，如 @sliverp/qqbot、@tencent-connect/openclaw-qqbot 等。
-#
-# 用法:
-#   upgrade-via-alt-pkg.sh --pkg <包名> --version <version>   # 指定包+版本
-#   upgrade-via-alt-pkg.sh --pkg <包名>                        # 指定包，安装 latest
-#   upgrade-via-alt-pkg.sh --appid <appid> --secret <secret>   # 首次安装时配置
-#   upgrade-via-alt-pkg.sh --no-restart                        # 只做文件替换，不重启
-#
-# 示例:
-#   bash scripts/upgrade-via-alt-pkg.sh --pkg @sliverp/qqbot --version 1.5.1
-#   bash scripts/upgrade-via-alt-pkg.sh --pkg @sliverp/qqbot --version 1.5.4
-#   bash scripts/upgrade-via-alt-pkg.sh --pkg @tencent-connect/openclaw-qqbot --version 1.6.4
-#   bash scripts/upgrade-via-alt-pkg.sh --pkg @sliverp/qqbot
-#   bash scripts/upgrade-via-alt-pkg.sh --pkg @sliverp/qqbot --version 1.5.4 --appid 12345 --secret abc123
