# Version 1.4

Version 1.4 of mod_wsgi can be obtained from:

> http://modwsgi.googlecode.com/files/mod_wsgi-1.4.tar.gz

## Bug Fixes

1. A negative value for content length in response wasn’t being rejected. Where invalid header was being returned in response original response status was being returned instead of a 500 error.

2. Fix bug which was resulting in logging destined for !VirtualHost !ErrorLog going missing or ending up in main Apache error log.

## Features Added

1. Optimise sending of WSGI environment across to daemon process by reducing number of writes to socket. For daemon mode and a simple hello world application this improves base performance by 40% moving it significantly closer to performance of embedded mode.

This is a backport of change from version 2.0 of mod_wsgi.
