A changelog is a chronological record of all notable changes made to a product — new features, improvements, bug fixes, and deprecations. While originally designed for developers, modern changelogs are public-facing communications that keep customers informed and engaged.
Effective changelogs do more than list changes. They tell the story of a product's evolution, communicate momentum, and give existing users reasons to return. When a changelog entry links to the customer feedback that inspired a feature, it closes the feedback loop — showing users that their voice directly shaped the product.
Regular changelog publishing is correlated with lower churn. Customers who know what's being shipped are more patient about missing features and more loyal overall. Many teams publish weekly or bi-weekly changelogs as part of their product communication strategy.
FeatureSay's changelog publisher lets teams write rich release notes, auto-notify customers who voted for shipped features, and embed the changelog on their own website. RSS feeds and API access make it easy for customers to subscribe.
