We will rarely do point release posts but theres been an important change in 2.0.7 that anyone with a customized estimate and/or invoice template should know about.
Estimate and Invoice templates will no longer use the wp_head and wp_footer, instead they will use si_head and si_footer (respectively). This prevents your estimate/invoices templates from being subjected to overzealous
plugins and themes that inject code with those standard template hooks.
If you’ve created a custom template, you should look into modifying your templates to use these new functions, since backwards compatibility will not be supported for ever.
The documentation on customizing your templates has been updated, since adding your own CSS has changed drastically — for the better. If you have any issues please contact support.
