[drupal-docs] url rewrite docs update (versioning)

[Gabor Hojtsy]

Hi,

Following the change of the mass URL aliasing (for the good for i18n :),
I have updated the module upgrade guide, so that it instructs authors on
how to use the new system. I am supposed to update the documentation
page on mass URL aliasing too: http://drupal.org/node/23708 But I don't
know how to go now about versioning. I am probably supposed to keep
information for 4.6 for some time, but I need to include information for
4.7 too. How is this done?

Thanks,
Goba
