What Is a Changelog? (And Why Your Product Needs One)

You shipped 40 features last year.

Your customers know about 3 of them.

Not because your features were bad. Because nobody knew they existed.

That's the problem changelogs solve.

The Problem: Shipping Features Into the Void

Here's what usually happens:

• Monday: You spend 60 hours building dark mode.
• Tuesday: You write "bug fixes and improvements" in your release notes.
• Wednesday: 12 people notice.
• Thursday: You wonder if it was worth building.
• Friday: You start questioning everything.

Sound familiar?

The feature wasn't the problem. The announcement was.

So What Is a Changelog?

A changelog is a record of what changed in your product.

That's it. That's the definition.

But here's what a good changelog actually does:

• Shows what changed (not just "improvements")
• Explains why it matters (saves time, solves pain, enables new workflows)
• Makes it easy to try (screenshots, links, clear instructions)
• Reaches people who care (email, in-product, social)

Think of it like this:

Without a changelog: You're throwing features into a black hole.

With a changelog: You're launching them like products.

Real Example: Before vs After

Let me show you what this looks like in practice.

Before (What Most People Write):

Version 2.3.1
- Bug fixes
- Performance improvements
- Various updates

Result: 12 people noticed. Nobody used the new features.

After (What Actually Works):

🎉 Dark Mode Is Here

You asked for it. We built it.

Now you can work at night without burning your retinas.

What's new:
- System-default dark mode (auto-switches at sunset)
- Manual toggle in Settings
- Optimized for OLED screens (true black backgrounds)

How to enable:
Settings → Appearance → Dark Mode

Questions? Reply to this email.

— The Team

Result: 847 people noticed. 320 enabled it within 48 hours.

Same feature. Different announcement. 70x more engagement.

That's what a changelog does.

Wait, Changelogs Aren't Just for Software?

No.

If your product evolves, it needs a changelog.

Let me show you what this looks like across different products:

1. Software & SaaS (The Obvious One)

Examples: Linear, Stripe, Figma, Notion, Superhuman

What they announce:

• New features (dark mode, bulk edit, API endpoints)
• Improvements (3x faster loading, better search)
• Breaking changes (API v1 sunset, migrate by Dec 1)

Bug fixes (Safari upload issue resolved)

Why it matters:

• Users discover features they'd otherwise miss
• Support tickets decrease (fewer "how do I..." questions)
• Engagement increases (people use what they know exists)
• Churn decreases (users see continuous improvement)

Real numbers from Linear:

• Average changelog email open rate: 62%
• Average feature adoption from changelog: 34%
• Compared to: 8% adoption for unannounced features

2. E-books & Digital Products

Who needs this: Gumroad creators, self-published authors, info product sellers

What to announce:

• New chapters added (3 new chapters on AI automation)
• Content updates (updated all 2024 examples to 2025)
• Fixes and improvements (fixed 17 typos in Chapter 7)
• Format additions (now available in audiobook)

Why it matters: You spent 40 hours adding 3 new chapters to your e-book.

You updated the file on Gumroad.

You maybe tweeted "Updated the book."

Result: 8% of buyers re-downloaded.

92% of your buyers have the old version. They paid you. You improved it. They don't know.

With a changelog:

The Bootstrap Way - Version 2.3
November 2025

What's New:
- 3 new chapters on AI automation (40 pages)
- Updated all pricing examples (2025 market rates)
- Added 12 new case studies
- Fixed 17 typos in Chapter 7

You already own this. Re-download here: [link]

— George

Email 892 buyers. 67% re-download. 23 new reviews: "Author keeps improving this book!"

That's the difference.

3. Online Courses

Who needs this: Teachable, Thinkific, Podia creators

What to announce:

• New modules/lessons (Module 8: Advanced Prompting - 5 lessons, 47 minutes)
• Updated content (Re-recorded Lesson 3 with better audio)
• New resources (Added: Prompt template workbook)
• Platform changes (Moved to new course platform)

The problem:

Student bought your course 6 months ago. Finished all 47 lessons.

You added 5 new lessons since then.

They don't know. They're not checking. They're not coming back.

You did the work. They don't benefit.

With a changelog:

Course Update - November 2025

New This Month:
- Module 8: Advanced AI Prompting (5 lessons, 47 min)
- New downloadable: Prompt Template Workbook
- Updated: All API pricing (everything changed in October)

You already own this. Go watch: [link to Module 8]

Questions? Hit reply.

Email 1,247 students. 412 watch the new module within 48 hours. 67 tag you on Twitter: "This course keeps getting better!"

4. Consulting & Services

Who needs this: Agencies, consultancies, service businesses

What to announce:

• New service packages (Launched: 5-Day Sprint Intensive)
• Pricing changes (Updated: Monthly retainer options)
• Team changes (Welcome Sarah, new Partner)
• Service improvements (Now offering: Sunday emergency support)

Why it matters:

You changed your pricing. Added new packages. Your clients don't know. They're still buying the old thing.

New client emails: "Do you offer X?"

You: "Yes! Since March!"

Them: "Oh. Wish I knew."

You literally lost revenue because nobody knew you offered it.

With a changelog:

ANC Service Updates - November 2025

We've added:

1. ANC Sprint (5-Day Intensive)
   Fast-track your O-1 visa eligibility
   In-person in Toronto or NYC
   $15K → Book here: [link]

2. Monthly Retainer Option
   Ongoing advisory + network access
   $5K/month → Learn more: [link]

Questions about which is right for you?
Reply to this email. I read everything.

— George

Email 340 past clients and warm leads. 3 book the Sprint in the first week.

= $45K from one email.

That's why service businesses need changelogs too.

5. Other Use Cases (Yes, Really)

Newsletters: "We're changing our format. Here's why and what to expect."

APIs: "v2.0 breaking changes. Action required: Migrate by December 1. Here's the guide: [link]"

Physical products: "We reformulated. Now 30% more effective. Same price. Details: [link]"

Communities: "New Discord channels, updated rules. Here's what changed: [link]"

Podcasts: "New format: 20-minute episodes every Tuesday. Here's why we're changing: [link]"

If it evolves, it needs a changelog.

The Anatomy of a Great Changelog Entry

Good changelogs follow a pattern. Let me break it down:

The Formula: Before/After/Impact

• Before: What was the pain point?
• After: What's different now?
• Impact: What can users do now that they couldn't before?

Let's see this in action:

Example 1: Feature Launch (Linear)

Triage Mode Is Here

Before: Reviewing issues meant opening each one individually.
Took 20 minutes to triage 50 issues.

After: Triage mode lets you review in bulk.
Keyboard shortcuts, instant actions, auto-advance.

Impact: Review 50 issues in 5 minutes.

How to use: Press 'T' or click Triage in the sidebar

[Screenshot showing triage mode]

Try it: [link]

Why this works:

• Clear headline (what's new)
• Quantified benefit (5 min vs 20 min)
• Visual proof (screenshot)
• Easy to try (keyboard shortcut + link)

Example 2: Performance Improvement (Vercel)

3x Faster Build Times

Before: Average build time: 4.2 minutes

After: Average build time: 1.4 minutes

Impact: Ship faster. Deploy 3x more often.

What we did:
- Rebuilt caching layer
- Parallelized dependency installation  
- Optimized image processing

[Chart showing before/after build times]

Nothing to configure. It just works.

Why this works:

• Led with the number (3x)
• Showed the data (chart)
• Explained the change (transparency)
• No action required (automatic improvement)

Example 3: Bug Fix (Dropbox)

Fixed: Safari Upload Issue

Before: File uploads failed on Safari 17+ with "Upload failed" error.

After: Uploads work perfectly on all browsers.

Impact: If you're on Safari (30% of you), you can upload without switching browsers.

What happened: Safari's new security policy broke our upload handler. We rebuilt it to comply.

Affected users: ~450 of you reported this in the past week. Thanks for the reports.

Try uploading again: [link]

Why this works:

• Acknowledged the problem (didn't hide it)
• Explained what happened (transparency)
• Thanked users who reported (community)
• Clear that it's fixed (try again)

What Makes a Good Changelog? (Checklist)

Use this checklist for every changelog entry:

Writing:

• Clear headline (not jargon, not vague)
• Explains why it matters (not just "what")
• Quantified when possible (3x faster, saves 45 min, 30% more effective)
• Casual, human tone (not corporate speak)
• Short paragraphs (3-4 lines max)

Visual:

• Screenshot for UI changes (show, don't just tell)
• GIF for workflow changes (show the before/after in motion)
• Chart for performance improvements (visualize the data)
• Code example for API changes (show old way vs new way)

Distribution:

• Published on changelog page (permanent record)
• Email to subscribers (reaches people who care)
• In-product notification (modal or notification bell)
• Social media post (Twitter/LinkedIn for discovery)

Usability:

• Easy to try (clear link or instructions)
• Answers "what do I do?" (next steps)
• Acknowledges impact (who this affects, who it doesn't)

If your changelog hits 10+ of these, you're in the top 20%.

Common Changelog Mistakes (And How to Avoid Them)

Mistake 1: "Bug Fixes and Improvements"

Why it's bad: Generic. Vague. Nobody cares.

Fix it:

DON'T: "Bug fixes and improvements"

DO: "Fixed: Images not uploading on Safari. If you saw 'Upload failed' errors this week, try again - it's working now."

The rule: Be specific. Name the bug. Say it's fixed.

Mistake 2: Feature Dumps

Why it's bad: 47 bullet points. Nobody reads it. Nothing stands out.

Fix it:

DON'T

Version 2.3:
- Added dark mode
- Improved search
- Fixed bugs
- Updated icons
- Enhanced performance
- Added filters
- Updated docs
- [40 more bullets]

DO:

Version 2.3: Dark Mode + Faster Search

This month's highlights:

1. Dark Mode (Finally!)
   Toggle in Settings. Your eyes will thank you.
   [Screenshot]

2. Search Is 3x Faster
   Average search time: 0.8s (was 2.4s)
   [Chart]

See all 47 changes: [link to full changelog]

The rule: Highlight 2-3 big things. Link to full list for those who want details.

Mistake 3: No Visuals

Why it's bad: Text alone doesn't show the change. Users can't imagine it.

Fix it:

DON'T: "We redesigned the dashboard to be cleaner and more intuitive."

DO: "We redesigned the dashboard. Here's the before and after: [side-by-side screenshots with arrows showing key changes]"

The rule: If it's visual, show it. Screenshots > descriptions.

Mistake 4: No Distribution

Why it's bad: You published the changelog. Nobody saw it. Features die in silence.

Fix it:

Don't just publish. Distribute:

• Email subscribers (50-70% open rates)
• Tweet/LinkedIn post (discovery)
• In-product modal (high visibility)
• Docs/help center (searchable)

The rule: 1 hour writing, 1 hour distributing. Both matter equally.

Mistake 5: Corporate Speak

Why it's bad: Sounds robotic. Not human. Users tune out.

Fix it:

DON'T: "We are pleased to announce the availability of our enhanced dashboard experience, featuring optimized workflows and improved user interface elements."

DO: "The dashboard is faster and cleaner. You'll notice. [Screenshot]"

The rule: Write like you're texting a friend. Remove corporate jargon.

Real Examples: Learn from the Best

Let's look at how successful companies write changelogs.

Linear: Software Changelog Done Right

What they do well:

• Clear headlines ("Triage mode is here")
• GIFs showing workflows (not static screenshots)
• Quantified benefits ("Review 50 issues in 5 minutes")
• Keyboard shortcuts highlighted (power users love this)
• Consistent format (users know what to expect)

Example entry:

Triage Mode

Keyboard-first issue review. Press T to start.

Actions:
- A - Archive
- S - Snooze  
- D - Done
- I - Assign to me

[GIF showing 10 issues triaged in 15 seconds]

Linear users who use triage mode review 4x more issues per day.

Try it: Press T

Why it works: Shows the workflow. Quantifies the benefit. Makes it easy to try.

Steal this: Use keyboard shortcuts, show the workflow in motion, quantify the improvement.

Stripe: API Changelog Excellence

What they do well:

• Serious about breaking changes (6-month warning)
• Code examples (old way vs new way)
• Migration guides (step-by-step)
• Impact assessment (which integrations affected)
• Timeline clarity (action required by date)

Example entry:

API v2.0 Migration Guide

Action required by June 1, 2026

What's changing:
- Authentication moved to OAuth 2.0
- Webhook payload structure updated
- Rate limits increased to 10,000/hour

Why it works:

• 6-month warning (respectful)
• Shows exact code change (actionable)
• Impact assessment (who's affected)
• Support email (help available)

Steal this: Give long warnings for breaking changes. Show code. Offer support.

Figma: Visual Product, Visual Changelog

What they do well:

• Screenshot-heavy (it's a visual product)
• Before/after comparisons (side-by-side)
• Use cases explained (when to use this)
• Community feedback acknowledged ("You asked for it")

Example entry:

Auto Layout: Absolute Positioning

You asked for it. We built it.

Before: Elements in auto layout had to follow the flow.
After: Pin elements to specific positions (like CSS absolute).

[Side-by-side comparison GIF]

Use cases:
- Floating action buttons
- Overlay badges on images
- Sticky headers in scrolling frames

How to use:
Select element → Right panel → Position → Absolute

Tutorial: [link]

Why it works:

• Acknowledges user requests
• Shows before/after visually
• Lists specific use cases
• Links to tutorial

Steal this: Show before/after. List use cases. Link to tutorials.

How to Start Your Changelog (Step-by-Step)

Step 1: Choose Where to Publish

Options:

A. Dedicated changelog page

• URL: yourproduct.com/changelog
• Tools: SimpleDirect, Headway, Beamer, or custom-built
• Best for: Software, SaaS, APIs

B. Blog/newsletter

• Medium, Substack, Ghost, or email
• Best for: E-books, courses, content products

C. Community channels

• Discord, Slack, email list
• Best for: Small products, beta, early-stage

My recommendation: Start simple. Use what you already have (blog, email list). Add dedicated tools later when you have volume.

Step 2: Set Up Distribution

How will people know you published?

Email subscribers (highest engagement)

• ConvertKit, Mailchimp, Substack
• Send weekly digest or per-update emails
• Open rates: 50-70% for product updates

In-product notifications (best for software)

• Modal on login (major features only)
• Notification bell (all updates)
• Banner (urgent changes)

Social media (discovery)

• Twitter thread (5-7 tweets with key changes)
• LinkedIn post (more professional framing)
• Product Hunt (major launches only)

RSS feed (for power users)

• Some users genuinely love RSS
• Easy to set up, low maintenance

Start with: Email + social. Add others as you grow.

Step 3: Create Your First Entry

Use this template:

[HEADLINE - Clear, specific, benefit-driven]

[BEFORE/AFTER/IMPACT - 2-3 sentences]

[VISUAL - Screenshot, GIF, or chart]

[HOW TO USE - Clear instructions or link]

[QUESTIONS? - Reply email or support link]

Example (Software):

Bulk Edit Is Here

Before: Changing 50 tasks meant clicking each one individually.
After: Select all, edit once. 50 tasks in 3 clicks.
Impact: Saves 45 minutes per sprint.

[GIF showing bulk edit in action]

How to use:
1. Select multiple tasks (Shift+Click or Cmd+A)
2. Right-click → Edit Selected
3. Make your changes

Step 4: Measure What Matters

Track these 5 metrics:

1. Email open rate

• Target: 50%+ for product updates
• If lower: Test subject lines, send time

2. Click-through rate

• Target: 15-25% click "Try it" or docs link
• If lower: Stronger CTAs, clearer value prop

3. Feature adoption

• Target: 30%+ try the new feature within 7 days
• If lower: Make it easier to find/use

4. Time on changelog page

• Target: 90+ seconds (they're reading, not bouncing)
• If lower: Better formatting, more visuals

5. Support ticket reduction

• Target: 10-20% fewer "how do I..." tickets after good communication
• If lower: Address common questions in changelog

Don't track:

• Social media likes (vanity metric)
• Total subscribers (not tied to outcomes)
• Number of updates (quality > quantity)

FAQ: Changelog Questions Answered

How often should I publish changelog updates?

It depends on your product type:

Software/SaaS:

• Small updates: Weekly digest email (Friday 9am)
• Major features: Immediately
• Bug fixes: Bundle into weekly (unless critical)

E-books/Digital products:

• When you make meaningful updates (new chapter, major revision)
• Don't announce typo fixes (bundle 10+ minor fixes)

Courses:

• New modules: Immediately
• New lessons: Weekly digest
• Minor updates: Monthly recap

Services:

• New offerings: Immediately
• Pricing changes: 30-day advance notice
• Process improvements: Quarterly recap

The rule: Meaningful updates get announcements. Tiny fixes get bundled.

Should I announce bug fixes?

Yes, IF:

• The bug affected many users (10%+)
• Users reported it (they want to know it's fixed)
• It was causing pain (crashes, data loss, slow performance)

No, IF:

• It was invisible to users
• It affected <1% of users
• It was a minor visual glitch

Example of good bug fix announcement:

Fixed: Safari Upload Issue

If you saw "Upload failed" errors on Safari this week, that's fixed now.

What happened: Safari 17's new security policy broke our upload handler. We rebuilt it.

Affected: ~450 of you reported this. Thanks for the reports.

Try uploading again: [link]

What if I don't have anything to announce?

Don't force it.

No updates = no changelog entry.

But here's a pro move: "Behind the scenes" updates

November 2025: What We're Working On

No new features this month, but here's what's in progress:

- Rebuilding search (3x faster, launching December)
- Dark mode design (in review)
- API v2 documentation (draft complete)

See you in December with some launches.

This keeps people engaged even when you're not shipping.

Do I need a changelog if I'm pre-launch?

Yes.

Especially if you're building in public.

"Development updates" = changelog for products in development.

Example:

SimpleDirect Changelog: Week 23

What shipped:
- Email notification system (finally working)
- Screenshot annotation tool (weirdly addictive)
- RSS feed (debugged the random failures)

What broke:
- Template system (scrapped, rebuilding)

What's next:
- Public beta opens in 7 days

Follow the journey: [link]

This builds anticipation and shows progress.

What's the difference between a changelog and release notes?

Same thing, different names.

• Tech companies say "changelog"
• Enterprise software says "release notes"
• Content creators say "updates" or "version history"

Pick whichever fits your brand. The format is the same.

The Bottom Line

You don't have a feature problem.

You have a communication problem.

You're shipping updates. Your users don't know they exist.

That's what changelogs fix.

Good changelogs:

• Make features visible
• Drive adoption
• Reduce support tickets
• Show continuous improvement
• Build trust

Bad changelogs:

• "Bug fixes and improvements"
• Generic bullet lists
• No visuals
• No distribution
• Corporate speak

No changelogs:

• Features die in silence
• Users don't know you're improving
• They wonder if the product is dead
• They churn

Your choice:

Ship in silence, or ship with a changelog.

The work is the same. The results are 70x different.
