Beyond the upgrade our system’s architecture has remained stable as we slowly add more integrations: new gems (to me) used this year included ferrum (for testing PayPal) and facebookbusiness. I also published paypal-sdk-subscriptions (with contributions) and activemerchant-flexpay. iContact reimplemented their API following a divestiture to j2 resulting in various small revisions to pocus. I’ve made no new contributions to ActiveAdmin apart from some StackOverflow answers, but I did finish the merge of Polyamorous and provide a stop-gap fix to Ransack with Rails 6.0.1. Formtastic became another ActiveAdmin dependency transitioned from the original author after falling into neglect.
