Timed releases for mobile apps

What this post added

This post details the adaptation of Facebook's web release process for mobile applications (Android and iOS). It introduces a date-driven release model, moving away from feature-driven development to enable predictable release cycles (4-8 weeks). This approach prioritizes stability and performance updates, allowing them to ship independently of feature completion. The post also highlights the unique challenges of mobile releases, such as higher stakes for crashes and the inability to perform gradual rollouts, necessitating a higher quality bar and careful scrutiny of changes. It also mentions code and test reuse across platforms (e.g., main Facebook app and Messenger app on iOS/Android) to improve efficiency.
