Hi folks!

We are excited to announce that Tengine-1.4.4 (development version) has  
been released. You can either checkout the source code from GitHub:  
[GitHub - alibaba/tengine: A distribution of Nginx with some advanced features](https://github.com/alibaba/tengine) or download the tarball directly:  
[http://tengine.taobao.org/download/tengine-1.4.4.tar.gz](http://tengine.taobao.org/download/tengine-1.4.4.tar.gz)

The highlight of this release is the session\_sticky module which  
supports  
session persistence between a client and a server. By using this module,  
subsequent requests will be dispatched to the same upstream server as  
the first request. Its syntax is very similar to HAProxy’s.

BTW, Tengine is now based on the Nginx-1.2.7, the latest stable version.

The full changelog is as follows:  
\*) Feature: added the session\_sticky module by using which one client  
can be always served by the same upstream server. (dinic)

\*) Feature: now the sysguard module can protect the server based on  
the amount of free memory. (lifeibo)

\*) Feature: added support for geoip regional database in geoip module.  
(jasonlfunk)

\*) Feature: log\_empty\_request can also disable the logs for timeout  
(408)  
empty request. (yaoweibin)

\*) Change: merged changes between Nginx-1.2.5 and Nginx-1.2.7.  
(cfsego)

\*) Change: CPU affinity is off by default now. (cfsego)

\*) Bugfix: fixed a bug that sysguard and upstream\_check module didn’t  
compile on Solaris 11. (lifeibo, yaoweibin)

\*) Bugfix: fixed a bug with TFS module that it might return bad  
values.  
(zhcn381)

\*) Bugfix: fixed a bug with TFS module that it might corrupt large  
files.  
(zhcn381)

For those who don’t know Tengine, it is a free and open source  
distribution of Nginx with some advanced features. See our website for

Have fun!
