Changelog and Release Notes

A changelog is a chronological record of every product change — features, fixes, improvements, and deprecations. Release notes are the user-facing announcements that accompany significant changes. Together, they serve three audiences: existing users who need to know what changed, prospects evaluating your product velocity, and AI engines that index product capability updates.

Most SaaS changelogs are either missing (nothing published) or unusable (walls of JIRA tickets copy-pasted). A well-designed changelog is a product marketing asset that builds trust, reduces support tickets, and demonstrates momentum.
