What Is a Changelog?
A changelog is a running record of product changes, fixes, and improvements published over time so customers and internal teams can see what changed in each release.
Why does it matter?
A changelog gives product, support, and customer-facing teams one source of truth for shipped changes. In B2B SaaS, it helps customers discover updates, helps PMMs plan announcements, and helps support teams explain what changed without digging through tickets or commits.
Examples
Added SAML SSO support for enterprise workspaces.
Fixed duplicate Slack notifications in digest emails.
Improved dashboard load time by 35% for large accounts.

FAQ
Is a changelog the same as release notes?
Not exactly. A changelog is usually a running historical record of changes, while release notes are often more curated and customer-facing.
Should every product have a changelog?
Most SaaS products benefit from one because it creates continuity and gives customers a clear place to see what has changed over time.
