10.1.2. Packaging Changes in Apache HTTP Server 2.0
Starting with Red Hat Linux 8.0, the Apache HTTP Server packages were renamed. Also, some related packages were renamed, deprecated, or incorporated into other packages.
Below is a list of the packaging changes:
*The apache, apache-devel and apache-manual packages were renamed httpd, httpd-devel and httpd-manual respectively.
*The mod_dav package were incorporated into the httpd package.
*The mod_put and mod_roaming packages were removed, since their functionality is a subset of that provided by mod_dav.
*The mod_auth_any and mod_bandwidth packages were removed.
*The version number for the mod_ssl package is now synchronized with the httpd package. This means that the mod_ssl package for Apache HTTP Server 2.0 has a lower version number than mod_ssl package for Apache HTTP Server 1.3.
