Apache2.0a1新特性（英文，我的英文太差，只能读懂。）

Core Enhancements:

Unix Threading
On Unix systems with POSIX threads support, Apache can now run in a hybrid multiprocess, multithreaded mode. This should improve scalability.

New Build System
The build system has been rewritten from scratch to be based on autoconf and libtool. This makes Apache@#s configuration system more similar to that of other packages.

Multiprotocol Support
Apache now has some of the infrastructure in place to support serving multiple protocols. mod_echo has been written as an example.

Better support for non-Unix platforms
Apache 2.0 should be faster and more stable on non-Unix platforms such as BeOS, OS/2, and Windows. With the introduction of platform-specific multiprocessing modules and the Apache Portable Runtime, these platforms can now avoid using POSIX-emulation functions that are sometimes buggy and always hurt performance.

New API
The API for modules has changed significantly for 2.0. Many of the module-ordering problemsfrom 1.3 should be gone. 2.0 does much of this automatically, and module ordering is now done per-hook to allow more flexibility. Also, new calls have been added that should allow
modules to do more without requiring patching of the core Apache server.
