CHANGELOG.md

@@ -10,12 +10,14 @@ Write each change in both `### English` and `### 中文` under `## Unreleased`.
 - Replace native Logs and Models filter dropdowns with compact HeroUI Select controls that match the 32px toolbar
 - Add named client API keys with optional provider allowlists, and show the console administrator key on System
 - Store an empty client-key provider allowlist as `[]` instead of JSON `null`
+- Keep the v0.2.20 bytes for provider-model settings migration 007, and accept the later tab-indented checksum so existing databases can boot
 
 ### 中文
 
 - Logs 和模型页的筛选下拉改用紧凑 HeroUI Select，高度对齐 32px 工具栏
 - 新增可限制供应商的客户端 API 密钥，并在系统页显示控制台管理员密钥
 - 客户端密钥未限制供应商时写入 `[]`，不再存成 JSON `null`
+- 007 供应商模型设置迁移保持 v0.2.20 原文，并接受后来误改缩进后的 checksum，已有数据库可以启动
