The MailerLite Python SDK by Larry Brid is a work in progress that aims to interact with email marketing features of the API. It contains resources to work with campaigns, subscribers, and subscribers lists.
Facebook has added Codeless App Events to the latest version of the Facebook SDK. The new feature allows app owners to track interactions between app users with certain elements within an app (e.g. buttons, images, etc.). Codeless App Events is implemented through a visual tool to reduce coding.
