**What changed:** API v1 endpoints will stop working on March 15, 2026.

**What you need to do:**
1. Update your API calls to use v2 endpoints ([migration guide →](link))

3. Test your integration before March 15

**Timeline:**
- Now: v2 endpoints available, v1 still works
- March 1: v1 returns deprecation warnings
- March 15: v1 stops working

Writing Tips

Do

Group related changes together
Lead with the biggest/most requested change
Link to documentation for complex features
Include who requested it ("By popular request:")
Show migration paths for breaking changes
Date every entry

Don't

Don't say "various bug fixes" — list specific fixes or skip them
Don't include internal references (PR numbers, ticket IDs, branch names)
Don't use "Updated [feature]" without saying how
Don't list changes nobody cares about (dependency bumps, internal refactors)
Don't commit-dump — one changelog entry may represent many commits

Changelog Frequency

Product Type	Frequency	Notes
SaaS (continuous deploy)	Weekly batch	Group a week of changes
SaaS (major features)	Per feature launch	With blog post
Versioned software	Per version release	Tied to semver
API	Per version + deprecation notices	Include migration guides
Mobile app	Per app store release	Match store listing "What's New"

Common Mistakes

Mistake	Problem	Fix
Developer language	Users don't understand	Write what users can do
"Bug fixes and improvements"	Zero information	List specific fixes
No dates	Can't tell what's new	Date every entry
No visuals	Users skip text	Screenshot major features
Breaking changes buried	Users discover too late	Prominent warning + timeline
Commit log as changelog	Noisy, unhelpful	Curate and rewrite
