woocomerce 2, tabs

Hello,
I just updated my version of woocomerce to the latest one, and in my old version I added some tabs in the following way:

add_action( 'woocommerce_product_tabs', 'woocommerce_product_description_tab', 50 );
				add_action( 'woocommerce_product_tab_panels', 'woocommerce_product_description_panel', 50 );

Now i dont know how this works on the new version, it seems that there is not woocomerce_product_tabs anymore, or not on the same way as in the post.

Could you please help with this….
thanks sooo much in advance.
