It +does not list enhancements nor does it talk about compatibility concerns introduced +by earlier versions (for this, see their respective compatibility documents). Its focus +is primarily on what you need to know if you used v7 and want to use v8 without hassle. +<p>Version 8 offers a completely rewritten core rsyslog engine. This resulted in +a number of changes that are visible to users and (plugin) developers. +Most importantly, pre-v8 plugins <b>do not longer work</b> and need to +be updated to support the new calling interfaces. If you developed a plugin, +be sure to review the developer section below. +</p> +<h2>What Developers need to Know</h2> +<h3>output plugin interface</h3> +<p>To support the new core engine, the output interface has been considerably +changed. It is suggested to review some of the project-provided plugins for +full details. In this doc, we describe the most important changes from a high +level perspective. +<p><b>RS_RET_SUSPENDED is no longer supported when creating an action instance</b> +<p>This means a plugin must not try to establish any connections or the like +before any of its processing entry points (like beginTransaction or doAction) +is called. This was generally also the case von v7, but was not enforced in +all cases. In v8, creating action creation fails if anything but RS_RET_OK +is returned. + + +<a href="http://www.rsyslog.com/g/BSD">rsyslog BSD blocks info</a> +page for more information and how to upgrade your config. +<p>[<a href="manual.html">manual index</a>] [<a href="http://www.rsyslog.com/">rsyslog site</a>]</p> + +<p><font size="2">This documentation is part of the +<a href="http://www.rsyslog.com/">rsyslog</a> project.<br> +Copyright © 2013 by <a href="http://www.gerhards.net/rainer">Rainer Gerhards</a> and +<a href="http://www.adiscon.com/">Adiscon</a>.
