Reading/Web/Release timeline

This page attempts to track notable changes that impact the reading web experience in production (over the past 2 years). These will usually have an associated SWAT deploy due to the fact that the reading web team makes heavy use of feature flags.

🎂 is used to mark releases the team feels are worth celebrating and usually mark the end of a long line of work.
