Forum OpenACS Q&A: Re: aolserver 4.0 final?
The current AOLserver 4.0 betas have full support for virtual hosts and internationalization in the core modules - a few non-core modules might need updates. (Don has already updated nscache.) More AOLserver 4.0 testing and bug reporting with OpenACS, dotLRN, and i18n specifically would be terrific, if you have time - the more bug reports and patches people submit, the sooner it can be released! I'd say the betas are definitely stable enough for development and testing purposes. I also believe AOL has started stress-testing it internally.
