v4.28.2

4.28.2 - 2026-09-27

Fixes

• Fixed SQLite datetime fields being inferred as SQLModel UTCDateTime after dependency upgrades, which caused knowledge-base writes, dashboard statistics, and related database operations to fail for naive datetime values. (#10205, #10212, #10255)
• Fixed platform message-history cleanup using a local-time cutoff instead of UTC, which could leave records undeleted on hosts outside UTC. (#10255)

• 修复平台消息历史清理使用本地时间计算截止时间的问题，避免非 UTC 主机上出现消息未被删除的情况。 (#10255)
