eGroupWare is a web-based and multi-user groupware suite developed on a custom set of PHP-based APIs.

Here are some key features of "eGroupWare Enterprise Collaboration":

· email
· addressbook
· calendar
· infolog (notes, to-do's, phone calls)
· content management
· forum
· bookmarks
· wiki

Limitations:

· EGW does not need to be compiled. EGW is composed only of PHP, HTML and image files
· EGW needs a Database server. MySQL or PostgreSQL or MSSQL preferred. Can be local or remote.
· EGW needs a php4 enabled web server. Apache1.3.x with PHP4.3.x preferred.
· EGW may need an e-mail server. Can be local or remote and IMAP or POP.
· Please read the requirements and install-how-to in the download area.

What's New in This Release:

· The most important fix is PHP5.2 compatibility.
· Because of a nasty bug in the PHP5.2 mbstring extension, you have to additionally switch display_errors Off, to be able to work with eGroupWare using multibyte charsets like utf-8 (or anyway if you have mbstring.func_overload > 0). Otherwise you get tons of "empty haystack" warnings.
Package layout:
· eGroupWare packages (all formats) contain all maintained applications
· RPM: eGroupWare-app packages require an eGroupWare or eGroupWare-core package
· gz, bz2, zip: eGroupWare-contrib contains ALL unmaintained applications (Please note they are not maintained and bugfixed anymore! Install only the app(s) you really need.)
