* Fix - Empty price string showing up when a bundle without a base price contains optional-only, individually-priced items. Price string is now correctly showing up as "From: $0.00".
* Fix - Give Products support for bundles with static contents.
* Fix - Database upgrade from v5.0.x unable to complete when migrating thousands of bundles on some systems.
* Dev Fix - Prevent stock validation when adding bundles to orders using 'WC_PB_Order::add_bundle_to_order'.
* Tweak - Bundled products that are physically packaged in their bundle container now show up as individual options of their parent in Shipstation packing slips. Previously, they were listed in a single "Contents" option of their parent.
