OpenACS 5.9.0 is released

ANNOUNCE: OpenACS 5.9.0 final released

This release contains many security and performance improvements as well as new functionality. The new release differs from OpenACS 5.8.1 in the following points:
- PostgreSQL enhancements and cleanups to improve performance and maintainability of the basic data model
- Greatly improved HTML validity and protection against XSS attacks.
- Improved theming support to create responsive interfaces.
- Various new functionalities to ease debugging and to improve performance. 


看起來更新幅度還蠻大的版本。

更新：
就閱讀的資料，目前支援 AOLserver 與 NaviServer。但是我沒有時間測試，只是對 OpenACS ChangeLog 的 use tcl8.5 idioms 和一些變動有興趣，我想這應該是一個已經全部使用 Tcl 8.5 的版本。
