* Drop use of civicrm_stripe_plans table and just query Stripe each time. This prevents errors when they get out of sync
### Upgrading
**You should upgrade directly from 5.0.**
**Please upgrade to 5.0 if you are on ANY older version. Then upgrade directly to 5.2. You do not need to install 5.1 first.**
Make sure you run the extension upgrades immediately after updating the code. There are two MAJOR upgrade steps:
1. Migrate civicrm_stripe_customers table to match on contact_id instead of email address. This can be re-run if necessary using StripeCustomer.updatecontactids API.
