It is strongly advised to keep WordPress up to date.

WordPress 3.5 is the minimum version required for full functionality, as this version introduces the admin tools for customisation and media uploader.

Tales has been tested thoroughly across a wide range of devices — see browser support — using the WordPress test data.

The theme actually renders properly right back to WordPress 3.3. Older releases ship an incompatible version of jQuery which breaks some interactions. Regardless, it is not a good idea to be running anything but the latest.

Support can only be provided for the latest WordPress update.
