今天 Ghost 团队发布了 Ghost 0.5 RC1 版本，距离上次 0.4.2 版本已经过去了 4 个月了。
0.5 版本主要变化是：
- 将 Backbonejs 替换为 Emberjs 框架
- 支持多用户
Backbonejs 到 Emberjs 的变化主要是体现在技术层面，对于大部分用户几乎没有感知。而多用户模式将为团队博客提供有力支持。
既然提到多用户，那就必须说说用户角色和权限，Ghost 支持以下几种角色：
| Name | Description |
|---|---|
| Owner | Automatically has all permissions. There can only ever be one owner, the owner cannot be deleted |
| Admin | Has all permissions, except being able to transfer ownership of the blog |
| Editor | Has permissions to manage their posts, and the posts of authors. Also has permissions to add and edit author users. |
| Author | Has permissions to create and edit their own posts, and their own user details |
| No-Auth | User who is not authenticated - i.e. a reader on the blog |
详细情况可以参考这份文档： https://github.com/TryGhost/Ghost/wiki/User-Roles-&-Permissions
期待 0.5 正式版发布！
