Changelog Newsletter Creator

Overview

Convert technical changelog entries into engaging, user-friendly newsletter content suitable for email campaigns, blog posts, and release notes pages. This skill helps translate developer-focused change descriptions into benefits-oriented content for end users.

Quick Start

Provide a changelog file or list of changes, and specify the desired output format (email, blog post, or release notes page). The skill will:

1. Identify change types (features, fixes, improvements, breaking changes)
2. Rewrite technical descriptions in user-friendly language
3. Organize content by impact and importance
4. Format for the target medium

Detailed Instructions

Step 1: Parse Changelog Input

Accept changelog entries in various formats:

• Markdown CHANGELOG.md files (Keep a Changelog format)
• Git commit logs (structured or conventional commits)
• Raw change lists (bullet points or paragraphs)
• Release notes (existing technical documentation)

Identify and categorize:

• New features
• Bug fixes
• Improvements/enhancements
• Breaking changes
• Deprecations
• Security updates

Step 2: Transform to User-Friendly Language

Apply these transformation principles:

Technical → User-Friendly:

• "Fixed null pointer exception in payment processor" → "Resolved an issue that could cause checkout to fail"
• "Implemented OAuth2 authentication flow" → "Added secure single sign-on with your favorite services"
• "Optimized database query performance" → "Made the app faster and more responsive"
• "Deprecated legacy API endpoints" → "Upgrading our system for better reliability (action required)"

Focus on benefits, not implementation:

• What problem does this solve for users?
• What can users now do that they couldn't before?
• How does this improve their experience?

Step 3: Organize by Priority and Impact

Structure content by user impact:

1. Headline Features - Major new capabilities
2. Improvements - Enhanced existing features
3. Fixes - Resolved issues (group similar fixes)
4. Coming Changes - Deprecations or upcoming breaking changes

Prioritize what users care about most:

• Visible changes over internal improvements
• Fixes for common pain points
• Features that enable new workflows

Step 4: Format for Target Medium

Best Practices

Writing User-Friendly Content

1. Lead with benefits - Answer "What's in it for me?"
2. Use active voice - "You can now..." not "Users are able to..."
3. Be specific - "3x faster" not "improved performance"
4. Group related items - Don't list 20 individual bug fixes
5. Avoid jargon - No database names, framework versions, or architecture details unless necessary

Handling Different Change Types

Features:

• Emphasize new capabilities and use cases
• Include examples or screenshots when possible
• Link to tutorials or documentation

Bug Fixes:

• Focus on the user impact, not the technical cause
• Group similar fixes together
• Only highlight fixes for issues users likely experienced

Breaking Changes:

• Make them prominent (use warning emoji or styling)
• Explain what users need to do
• Provide migration guide links
• Give timeline if applicable

Internal/Infrastructure:

• Translate to user benefits (speed, reliability, security)
• Group under "Improvements" or "Performance"
• Don't list every dependency update

Tone and Style

• Conversational but professional - friendly without being overly casual
• Enthusiastic about improvements - celebrate wins
• Honest about issues - acknowledge and explain fixes
• Respectful of user time - be concise

Common Issues and Solutions

Too many minor changes to list: Group them by category and summarize. For example: "Fixed several issues with form validation" instead of listing 8 individual input field bugs.

Highly technical changes: Focus on the outcome, not the implementation. "Improved security" rather than "Implemented bcrypt password hashing with salt rounds."

Breaking changes requiring action: Always include: what's changing, why it matters, what users need to do, and when they need to do it by.

Nothing user-facing this release: If it's all internal improvements, frame it as: "Behind-the-scenes improvements for better performance, security, and reliability."

Additional Considerations

Segmentation

Consider creating different versions for different audiences:

• End users: Focus on features and user-visible fixes
• Developers/API users: Include API changes, SDK updates
• Admins: Highlight security, compliance, configuration changes

Linking Strategy

Always link to:

• Detailed documentation for complex features
• Migration guides for breaking changes
• Video demos or screenshots for visual features
• Full changelog for technical details

Timing

• Email newsletters: Monthly or quarterly summaries
• Blog posts: Major releases or significant feature launches
• Release notes: Every release, even minor ones
