+title: 1.5.0
+date: 2026-07-13
+description: 预签名上传链接、传输速度与剩余时间、迁移可从面板重试,以及七家云通用的对象标签读写
+---
+
+Nebula 1.5.0 在协作、传输可视化与对象元数据三处继续补齐。协作上新增**预签名上传链接**——生成一个 PUT 链接,别人无需你的密钥就能往指定路径上传文件,是「分享下载链接」的反面。传输面板更透明:进行中的传输显示**实时速度与预计剩余时间**,并且**迁移也能从面板重试**——补上了传输里最后一个不能重跑的类型。对象层面带来**可读写的对象标签**,给对象挂 key-value 元数据,为生命周期、权限与成本分摊打底,七家云通用。
+
+Nebula 1.5.0 rounds out collaboration, transfer visibility, and object metadata. For collaboration, **presigned upload links** let someone PUT a file to a path you choose without your credentials — the mirror image of a share-download link. The transfer panel is more transparent: in-flight transfers show **live speed and ETA**, and **migrations can now be retried from the panel** — the last transfer kind that couldn't be re-run. At the object level, **read/write object tags** attach key-value metadata that underpins lifecycle, access, and cost allocation, working across all seven clouds.

+
+## 分享与协作 | Sharing & Collaboration
+
+- **预签名上传链接**:为某个路径生成带签名的临时 PUT 链接,持链接者无需密钥即可上传一个文件,同样会过期。收集他人文件、让协作者上传产物,不必再分发临时凭证。
+- 一条 `curl -X PUT --upload-file 文件 "链接"` 即可上传;详情抽屉与右键菜单都能生成。
+
+Generate a signed, expiring PUT link for a path so whoever holds it can upload a file with no credentials — the reverse of the existing share-download link. Collect files or let collaborators drop artifacts without handing out temporary keys; a single `curl -X PUT --upload-file` does it. Available from the file context menu and the details drawer.
+
+## 传输面板 | Transfer Panel
+
+- **速度与剩余时间**:进行中的上传 / 下载 / 迁移在百分比之外显示实时速度与预计剩余时间(如 `45% · 3.2 MB/s · ~12s`),速度用滑动平均平滑,按文件数计量的文件夹任务保持纯百分比。
+- **迁移可重试**:取消或失败的跨云迁移现在也能在面板里一键重跑——此前它是唯一缺少「重试」按钮的传输类型,因为重跑需要的源端信息未被记下。
+
+In-flight uploads, downloads and migrations now show live speed and ETA next to the percentage (e.g. `45% · 3.2 MB/s · ~12s`), with the speed smoothed by a moving average; folder tasks counted by file keep a plain percentage. Cancelled or failed cross-cloud migrations can now be retried from the panel — previously the only transfer kind without a retry button, because the source it needs to re-run wasn't recorded.
+
+## 对象标签 | Object Tagging
+
+- **读写对象标签**:对象详情新增「标签」入口,弹出键值编辑器——加载现有标签、增删行、整套保存(存空即清空)。
+- 标签是生命周期规则、访问策略与账单分摊的元数据基石,经 `?tagging` 子资源实现,阿里云 / 华为 / 腾讯 / AWS / R2 / MinIO / 七牛七家通用。
+
+Object details gain a Tags action opening a key/value editor — load current tags, add or remove rows, and save the whole set (empty clears them). Tags are the metadata that drives lifecycle rules, access policies and cost allocation; implemented via the `?tagging` sub-resource and working across all seven clouds.
