This release adds many improvements, optimizations, new features and components. We have new modules, plug-in support, modular path extractors for the Spider, XMLRPC Client/Server interfaces and probably more stuff I'm currently incapable of recalling. The new plug-in functionality has been used to implement a passive proxy and an automated login plug-in allowing for scripted, form based, authentication. Using the passive proxy you can selectively choose the pages you want to audit by browsing them, login to the web-application and enable Arachni to audit AJAX based web pages by allowing it to see what your browser sees. The AutoLogin plug-in enables the framework to log-in to a given web application before the scanning process starts and alleviates the need to go through the hassle of creating and setting your own cookie-jar. The new XMLRPC services allow for remote and distributed –agent-like– deployment of Arachni.
