SabreDAV 可是使得你的Web应用程序很方便的集成 WebDAV 系统，支持大多数的客户端，包括 Mac OS X Finder, the Windows XP/Vista Explorer, DavFS2, Cadaver, NetDrive, and WebDrive. 支持 WebDAV 服务器 class 1, 2, 和 3. 实现了 RFC 2518 和 RFC 4918 的修订版，实现了 RFC 2617 认证。
SabreDAV 1.4.0 is released. Version 1.4.0 comes with many compatibility fixes and several new features. Note that this release is marked "Beta quality". The reason for this being that not all features are 100% completed, but we deemed it was important to get back to the "release early, release often" ideology. Regardless, it should be pretty stable.
There are also a number backwards compatibility breaks. Read Migrating from 1.3 to 1.4 for more information on how to upgrade.
