* Complete code refactor and many bugs fixed;
* Added multithreading support to set the maximum number of concurrent HTTP requests;
* Implemented SQL shell (`--sql-shell`) functionality and fixed SQL query (`--sql-query`, before called `-e`) to be able to run whatever SELECT statement and get its output in both inband and blind SQL injection attack;
* Added an option (`--privileges`) to retrieve DBMS users privileges, it also notifies if the user is a DBMS administrator;
* Added support (`-c`) to read options from configuration file, an example of valid INI file is sqlmap.conf and support (`--save`) to save command line options on a configuration file;
* Created a function that updates the whole sqlmap to the latest stable version available by running sqlmap with `--update` option;
* Created sqlmap .deb (Debian, Ubuntu, etc.) and .rpm (Fedora, etc.) installation binary packages;
* Created sqlmap .exe (Windows) portable executable;
* Save a lot of more information to the session file, useful when resuming injection on the same target to not loose time on identifying injection, UNION fields and back-end DBMS twice or more times;
* Improved automatic check for parenthesis when testing and forging SQL query vector;
* Now it checks for SQL injection on all GET/POST/Cookie parameters then it lets the user select which parameter to perform the injection on in case that more than one is injectable;
* Implemented support for HTTPS requests over HTTP(S) proxy;
* Added a check to handle NULL or not available queries output;
* More entropy (randomStr() and randomInt() functions in lib/core/common.py) in inband SQL injection concatenated query and in AND condition checks;
* Improved XML files structure;
* Implemented the possibility to change the HTTP Referer header;
* Added support to resume from session file also when running with inband SQL injection attack;
* Added an option (`--os-shell`) to execute operating system commands if the back-end DBMS is MySQL, the web server has the PHP engine active and permits write access on a directory within the document root;
* Added a check to assure that the provided string to match (`--string`) is within the page content;
* Fixed various queries in XML file;
* Added LIMIT, ORDER BY and COUNT queries to the XML file and adapted the library to parse it;
* Fixed password fetching function, mainly for Microsoft SQL Server and reviewed the password hashes parsing function;
* Major bug fixed to avoid tracebacks when the testable parameter(s) is dynamic, but not injectable;
* Enhanced logging system: added three more levels of verbosity to show also HTTP sent and received traffic;
* Enhancement to handle Set-Cookie from target url and automatically re-establish the Session when it expires;
* Added support to inject also on Set-Cookie parameters;
* Implemented TAB completion and command history on both `--sql-shell` and `--os-shell`;
* Renamed some command line options;
* Added a conversion library;
* Added code schema and reminders for future developments;
* Added Copyright comment and $Id$;
* Updated the command line layout and help messages;
* Updated some docstrings;
* Updated documentation files.
