* Fix: shipping bug when the packages for recurring orders were different to those for the initial order. Fixes compatibility with Table Rate shipping and occasional issues with manual renewals for products with a free trial or synchronised renewal date. Refactoring of shipping selection required to address the issue: shipping method selection fields are now displayed on checkout in the Recurring Totals section when the available recurring shipping rates are different to the rates for the initial order (either because the methods are different, the costs are different, or the package contents is different).

* Tweak: display details of product, shipping and tax line items at PayPal for subscription sign-ups via Express Checkout Reference Transactions instead of only displaying the billing agreement description.
* Tweak: add new wcs_get_address_type_to_display() method to have a single source for all localised address type display names

* Tweak: move user role filter to after the default roles section and introduce wcs_get_new_user_role_names() to allow custom code to more easily customise the role assigned to a user for subscription events.
* Fix: Product add-on incompatibility: make sure product add-ons are only applied once for manual renewal payments for a previously failed automatic renewal payment.
* Fix: Checkout Add-ons incompatibility: add subscription fee line items to the cart for manual renewal and resubscribe to make sure Checkout Add-ons are applied to manual renewals and resubscribes
* Fix: compatibility with remote updaters, like WP Remote, Jetpack Manage by activating subscriptions on 'init' not 'admin_init' because remote udpaters won't trigger that hook.

* Fix: make sure you can bulk edit variations before a variable product is saved with WooCommerce v2.5 by using the product type field

Instead, log the more general "Sign-up complete" order note whenever a subscription without an initial payment receives the first payment complete function call.
* Fix: don't allow resubscribing to subscriptions with a $0 / period price, because generally, this is done to charge the full cost of the subscription in the sign-up fee, and we don't charge sign-up fees on a resubscribe.
* Fix: occassional error when updating a subscription via the Edit Subscription screen: "Error updating subscription: A valid PayPal Billing Agreement ID value is required" caused by using disabled payment method meta fields (Subscriptions now uses readonly fields).
* Fix: send cancelled subscription emails to store managers when a subscription is deleted early in the process of deletion to ensure billing meta fields are still available to include in the email.
* Fix: log correct next payment date when processing a PayPal IPN payment request for a subscription that has a payment in the future. Also fixes an undefined index notice for these IPN requests for subscriptions with no free trial.

* Fix: always display order numbers not IDs to improve compatibility with plugins like Sequential Order numbers
* Fix: when a switch order's status is changed, don't cancel, suspend or mark the corresponding subscription as failed. Only do that on those status changes for the original order.
* Fix: display all subscriptions on the Subscriptions list table when filtering by payment method (previously the default posts per page value would be used, which is 5).
* Fix: leap year issues when creating subscription terms with PayPal Standard that can lead to prolonged free trial or subscription duration for subscripions that have an annual free trial or billing period.
* Fix: set correct subscription length options for subscription variations on the Edit Product screen when first loading the page (affects subscriptions with a billing interval other than 1)
* Fix: duplicate PayPal IPN blocking on sites running PHP prior to version 5.4.0.
2016.01.30 - version 2.0.9
* Notice: if you have customisations to the /add-to-cart/variable.php template you wish to apply to variable subscription products, you will need to create a new /add-to-cart/variable-subscription.php template in your theme as this version introduces a new template specifically for variable subscription products

* Tweak: flush rewrite rules on activation / deactivation rather than just on upgrade to ensure /view-subscription/ rewrites are always available

* Tweak: delete subscriptions on user deletion instead of simply trashing them
* Tweak: new filters for 3rd party developers to use for renewal/resubscribe: 'wcs_cart_contains_renewal', 'wcs_cart_contains_failed_renewal_order_payment', 'wcs_users_resubscribe_link_for_product', 'wcs_cart_contains_resubscribe'

* Fix: remove download permissions when product line items are switched to make sure customer only has access to line items of the product they are currently subscribed to
* Fix: when checking whether to apply a discount, only call is_valid_for_product() with WooCommerce 2.5+ because it will always return false in prior versions
* Fix: make sure subscriptions are cancelled before being deleted by using the correct hook name (they were already being correctly cancelled when trashed)
* Fix: do not redirect for auto-switching on limited subscriptions if switching has been disabled in the store
* Fix: always create a failed renewal order for PayPal IPN messages relating to a failure when the subscription is active because PayPal may send the subscription suspended message before the payment failed message and therefore, we'd mark the old renewal order as failed instead of a new renewal order
* Fix: make sure resubscribe orders do not incorrectly charge signup fees after a failed or pending payment on the resubscribe order
* Fix: ignore suspended payment PayPal IPN messages for subscriptions with any status other than 'active' to avoid exceptions when attempting to suspend a subscription pending-cancellation or custom status that can't be suspended
* Fix: display the # symbol before subscription numbers/IDs in all places where WooCommerce displays the # symbol before the order number/ID
* Fix: make sure subscriptions created with PayPal Standard are correctly cancelled when changing the customer changes the payment method to PayPal but the store now supports PayPal Reference Transactions

* Fix: When changing a subscription's payment method from PayPal to a different gateway via the Edit Subscription administration screen, suspend the existing subscription at PayPal to ensure no future payments are processed on it.
* Fix: Apply recurring cart discount coupons to products not excluded from that coupon even if the cart contains other products which are excluded from that coupon. Requires WooCommerce 2.5.

* Fix: Fix the logic checking for sync day in future by comparing the full date not just the day then the month/year if that day is after the current day. This ensures we don't see a day in the future with a month and year in the past or same as today as being a date in the future
* Fix: Display the resubscribe relationship in the admin edit order and subscription related orders table
* Fix: Directly access the `$_REQUEST'action'` variables instead of using `$wp_list_table->current_action()`. Fixes an issue where while filtering the admin subscriptions list table by customer, attempting to update a subscription status using the provided suspend, cancel and reactivate actions wouldn't actually update the status
* Fix: Honour previous filters applied to the admin subscription list table after updating an individual subscription status using the provided actions
2015.11.07 - version 2.0.5

* Fix: errors relating to an order awaiting payment that has been set to false or deleted instead of being unset in the WooCommerce session

* Fix: don't suspend then reactivate subscriptions at PayPal on a renewal (introduced with 2.0.3) because store manager don't like the extra status change entries logged at PayPal and also PayPal doesn't sent a Subscription reactivated IPN, but does send a Subscription suspended IPN, which could lead to subscriptions remaining on-hold incorrectly if IPN handling code for PayPal Express Checkout/Digital Goods was handling it
* Fix: customer facing change payment method process for gateways which need to use the Checkout > Pay page a 2nd time, for example, to collect credit card details

* Fix: Ignore PayPal's 'subscr_eot' IPN message completely. It is incorrectly documented and leads to assorted bugs when appearing at unexpected times, like immediately for subscriptions of only one payment, at the same time as the last payment and when a subscription is cancelled due to failed payments. Subscriptions internal scheduleding is now used exclusively for expiring a subscription and it's failed payment handling is used whenever a subscription payment fails.
