+- 费用金额按大小显示有效位数：低价模型的单次费用不再都显示成 $0.00，例如 $0.0014、$0.00673，常规金额仍保留两位小数。
+- 请求明细的账户筛选不再列出已归档账户。从已归档账户查看请求时，当前账户仍保留并注明「已归档」，不会只剩一个账户 ID。
+- 手机上使用侧边栏布局打开请求详情时，较长的来源记录 ID 会把字段名挤成竖排；现在字段名保持横排，长 ID 在数值列内折行。
+- 数据库结构未变，升级不需要先备份。

 - 本机采集器可以登记额外任务：`meterleaf-collector tasks add` 登记一条本机命令，由采集器的后台任务按间隔运行，有限时，失败只记日志，不影响同步，`status` 和 `tasks` 显示最近一次结果。用法见[本机采集器](docs/collector.md#额外任务可选)。

 - 同一账号从多个来源采集时，在来源账户菜单选择「合并额度与用量」，选定目标账户后确认。全部历史及后续用量都会归入目标，原来源记录仍可在请求明细查看，不做跨来源去重；若两个来源都记录了同一次请求，会累计两次。同一额度窗口使用最新快照，百分比不会相加，未知或到期状态仍如实显示。目标账户的名称和套餐保留。
 - 在目标账户的「合并额度与用量」弹窗查看已合并账户，点击「解除合并」恢复各自展示。原始记录不删除，同步不会覆盖合并关系；连续合并多个账户时，解除某一层也会带回合并到它的账户。合并和解除后报表需要重新计算，数据较多时稍等片刻。
 - 归档账户不在账户区显示。有归档账户时，标题右侧出现「已归档 N」，点击后查看归档列表，可在菜单中恢复或删除，点「使用中账户」返回。
+- 归档账户不再出现在请求明细的账户筛选里。从归档列表打开某个账户的请求时，筛选仍保留这个账户并注明「已归档」，切回「全部账户」即可退出。
 - 删除账户只移除账户展示，不会删除历史请求、累计统计，也不影响 Sub2API 或本机采集器。
 - 重命名的名称只在 Meterleaf 中显示，最长 40 个字，不会改动上游。清空名称或选择恢复原名后，重新显示上游提供的名称。
 - 套餐徽标按使用倍数分三档显示，同一档外观相同。Claude Pro、Claude Team Standard 与 ChatGPT Plus 为一档，Claude Max 5x、Claude Team Premium 与 ChatGPT Pro 5x 为二档，Claude Max 20x 与 ChatGPT Pro 20x 为三档。只知道订阅类型、不知道倍数时，例如只显示 Max 或 Team，不分档。无法识别的套餐只显示名称。

 手机上预估跟在已用费用之后，桌面账户列表在右侧单独显示。缺少有效比例、可计价消费或窗口失效时保留未知，不补零。快照可能包含其他入口的消费，本地请求只覆盖已采集来源，模型组合和供应商计量规则也可能变化，因此估值不是供应商承诺额度。
 
+金额按大小显示：常规金额保留两位小数，低于一美分时多显示几位有效数字并省略末尾的零，低价模型的单次费用不会都显示成 $0.00。导出文件保留未四舍五入的金额。
+
 Tokens 总量由普通输入、缓存读取、缓存写入和输出组成。推理 Tokens 是输出子集，不能再相加。缺失金额保留未知；可计价部分的合计不代表完整费用。两种美元口径和订阅 Credits 的区别见[计价说明](pricing.md)。
