 ### 📡 マルチチャネル管理
 複数のAIチャネルを同時に設定・監視できます。各チャネルは独立して動作するため、異なるタスクに特化したエージェントを実行できます。
+現在は各チャンネルで複数アカウントを扱え、Channels ページでアカウントの Agent 紐付けやデフォルトアカウント切替を直接管理できます。

 ### ⏰ Cronベースの自動化
 AIタスクを自動的に実行するようスケジュール設定できます。トリガーを定義し、間隔を設定することで、手動介入なしにAIエージェントを24時間稼働させることができます。

 ### 📡 Multi-Channel Management
 Configure and monitor multiple AI channels simultaneously. Each channel operates independently, allowing you to run specialized agents for different tasks.
+Each channel now supports multiple accounts, per-account agent binding, and switching the channel default account directly from the Channels page.

 ### ⏰ Cron-Based Automation
 Schedule AI tasks to run automatically. Define triggers, set intervals, and let your AI agents work around the clock without manual intervention.

 ### 📡 多频道管理
 同时配置和监控多个 AI 频道。每个频道独立运行，允许你为不同任务运行专门的智能体。
+现在每个频道支持多个账号，并可在 Channels 页面直接完成账号绑定到 Agent 与默认账号切换。

 ### ⏰ 定时任务自动化
 调度 AI 任务自动执行。定义触发器、设置时间间隔，让 AI 智能体 7×24 小时不间断工作。
