v2.1.0-rc.1

• Feature - Added synchronization options to subscription schemes.
• Feature - Introduced subscription switching for Simple and Variable products with subscription schemes. Bundles and Composites can't be switched just yet :)
• Feature - It's now possible to add products with subscription schemes and "subscription scheme-less" products to existing subscriptions. When viewing a product with subscription schemes, customers can load a list of active subscriptions matching the billing schedule of the chosen subscription scheme, and add the viewed product to one of them. Notes: 1) Feature must enabled under 'WooCommerce > Settings > Subscriptions > Add to Subscription > Products'. 2) Prorated subscription schemes are not supported.
• Feature - It's now possible to add entire carts with subscription options to existing subscriptions. When viewing a cart with subscription options, customers can load a list of active subscriptions matching the billing schedule of the chosen subscription option, and add the contents of their cart to an active subscription. Notes: 1) Feature must enabled under 'WooCommerce > Settings > Subscriptions > Add to Subscription > Carts'. 2) Prorated subscription schemes are not supported.
• Fix - Streamlined management of Bundles and Composites in subscriptions. It is no longer possible to remove individual child/container line items - removals are delegated to the container item.
• Fix - UX: When choosing a new variation SATT remembers the chosen subscription option, as it should.
• Tweak - Template tweaks for consistency, styling flexibility and more freedom to change things using filters.
• Tweak - Define the selected subscription scheme when adding a product to the cart using an 'add-to-cart' query string.
• Tweak - Improved support for Product Bundles and Composite Products.
