dotProject 2.1.7 is primarily a security release, along with several bug fixes
and new features over 2.1.6.
A number of SQL injection and XSS (Cross Site Scripting) vulnerabilities have
been resolved in this release and it is recommended that all users upgrade.
For users of dP before 2.1, this also fixes an upgrade bug that occurs if
the version is 2.1.1 or previous.
