Apache HTTP Server 1.3.29 Released

The Apache Software Foundation and The Apache HTTP Server Project are pleased to announce the release 
of version 1.3.29 of the Apache HTTP Server ("Apache"). This Announcement notes the significant changes 
in 1.3.29 as compared to 1.3.28. The Announcement is also available in German from 
http://www.apache.org/dist/httpd/Announcement.html.de.

This version of Apache is principally a bug and security fix release. A partial summary of the bug 
fixes is given at the end of this document. A full listing of changes can be found in the CHANGES file. 
Of particular note is that 1.3.29 addresses and fixes 1 potential security issue:

We consider Apache 1.3.29 to be the best version of Apache 1.3 available and we strongly recommend that 
users of older versions, especially of the 1.1.x and 1.2.x family, upgrade as soon as possible. No further 
releases will be made in the 1.2.x family.

Apache 1.3.29 is available for download from

http://httpd.apache.org/download.cgi

Binary distributions are available from

http://www.apache.org/dist/httpd/binaries/

This service utilizes the network of mirrors listed at:

http://www.apache.org/mirrors/

Please see the CHANGES_1.3 file in the same directory for a full list of changes.

As of Apache 1.3.12 binary distributions contain all standard Apache modules as shared objects (if 
supported by the platform) and include full source code. Installation is easily done by executing the 
included install script. See the README.bindist and INSTALL.bindist files for a complete explanation. 
Please note that the binary distributions are only provided for your convenience and current distributions 
for specific platforms are not always available. Win32 binary distributions are based on the Microsoft 
Installer (.MSI) technology. While development continues to make this installation method more robust, 
questions should be directed to the news:comp.infosystems.www.servers.ms-windows newsgroup.

For an overview of new features introduced after 1.2 please see

http://httpd.apache.org/docs/new_features_1_3.html

In general, Apache 1.3 offers several substantial improvements over version 1.2, including better 
performance, reliability and a wider range of supported platforms, including Windows 95/98 and NT (which 
fall under the "Win32" label), OS2, Netware, and TPE threaded platforms.

IMPORTANT NOTE FOR APACHE USERS: Apache 1.3 was designed for Unix OS variants. While the ports to non-Unix 
platforms (such as Win32, Netware or OS2) are of an acceptable quality, Apache 1.3 is not optimized for 
these platforms. Security, stability, or performance issues on these non-Unix ports do not generally apply 
to the Unix version, due to software's Unix origin.

Apache 2.0 has been structured for multiple operating systems from its inception, by introducing the Apache 
Portability Library and MPM modules. Users on non-Unix platforms are strongly encouraged to move up to 
Apache 2.0 for better performance, stability and security on their platforms.

Apache is the most popular web server in the known universe; over half of the servers on the Internet are 
running Apache or one of its variants.
