Joomla 1.5.17 is now released.
This upgrade contains several bug fixes and security patches. This release also fixes a couple of bugs introduced with Joomla 1.5.16. (Don't worry, we became aware of this problem while installing the previous version, so patched this temporarily.)
Now a mere week after previous upgrade (1.5.16 we are happy to announce that we have applied this latest upgrade to all our customer sites.
