What's New

New Currency Support

• Added Colombian Peso (COP) as a supported currency (#78)

Bug Fixes

• Fixed currency conversion display in subscription list to match dashboard behavior (#79)

Upgrade Notes

Important: Back up your data before upgrading.

Download a backup from Settings → Data Management → Download Backup before updating.

SubTrackr v0.5.0 introduces optional authentication to protect your subscription data, while maintaining our commitment to simplicity and privacy-first design.

⚠️ Important: Backup Your Data

Before upgrading, we strongly recommend backing up your data:

1. Navigate to Settings → Data Management
2. Click "Download Backup" to save your database
3. Store the backup file in a safe location

This ensures you can restore your data if anything goes wrong during the upgrade.

🎉 New Features

🎄 Holiday Themes (New!)

Spread holiday cheer with our new theming system!

• 5 Beautiful Themes: Default, Dark, Christmas, Midnight, Ocean
• 🎅 Christmas Theme: Festive red & green colors, gold accents, and gentle snowfall animation ❄️
• Easy Switching: Change themes instantly from Settings → Appearance
• Persistent: Your theme choice is saved automatically
• Accessible: Respects prefers-reduced-motion for animations

Perfect for the holiday season! Switch to the Christmas theme and enjoy the festive atmosphere while tracking your subscriptions.

Optional Authentication System

• OFF by default - Zero breaking changes for existing installations
• Single-user authentication with bcrypt password hashing
• Session-based login with secure cookies (HttpOnly, SameSite)
• "Remember me" option (30-day sessions)
• SMTP prerequisite check - ensures password recovery is always available

Password Reset Flow

• Complete forgot password → email reset link → set new password flow
• 1-hour token expiry for security
• Works seamlessly with existing SMTP configuration

CLI Password Reset (Perfect for Docker!)

• Reset admin password without email: ./subtrackr --reset-password
• Non-interactive mode: ./subtrackr --reset-password --new-password "yourpassword"
• Disable authentication: ./subtrackr --disable-auth
• Essential for Docker deployments when SMTP isn't configured

Security Section in Settings

• Easy toggle to enable/disable authentication
• Shows current authentication status
• Warns if SMTP is not configured (required for password recovery)
• Disable authentication option preserves credentials for re-enabling

🔒 Security Improvements

This release includes fixes for several security vulnerabilities identified during security review:

• Fixed: Open redirect vulnerability in authentication handlers
• Fixed: Timing attack in CLI password confirmation (now uses constant-time comparison)
• Fixed: Timing attack in token validation (constant-time string comparison)
• Fixed: Username enumeration via timing (always validates both username and password)
• Fixed: Password validation order in reset handler (prevents information leakage)
• Improved: Redirect URL validation with length limits (max 2048 characters)
• Improved: Error handling prevents authentication bypass

All authentication operations now use constant-time comparisons via crypto/subtle to prevent timing-based attacks.

📝 How to Enable Authentication

1. Configure SMTP first (Settings → Email Configuration)

   • Required for password recovery
   • Cannot enable login without email configured

2. Enable Login (Settings → Security)

   • Toggle "Require Login"
   • Set username and password (min 8 characters)
   • Click "Enable Authentication"

3. You'll be redirected to login on next page load

🐳 Docker Best Practices

Version Pinning (Recommended)

Always pin to specific versions instead of using latest:

# ❌ NOT RECOMMENDED - unpredictable updates
image: bscott/subtrackr:latest

# ✅ RECOMMENDED - controlled, predictable deployments
image: bscott/subtrackr:v0.5.0

Why Pin Versions?

1. Predictability - Know exactly what version is running
2. Stability - Avoid unexpected breaking changes
3. Reproducibility - Same image across all environments
4. Rollback Safety - Easy to revert to previous version
5. Testing - Test specific versions before upgrading production

Version Update Strategy

# docker-compose.yml
services:
  subtrackr:
    image: bscott/subtrackr:v0.5.0  # Pin to specific version
    volumes:
      - ./data:/app/db
    ports:
      - "8080:8080"
    restart: unless-stopped

Upgrade process:

1. Backup your data (via Settings UI)
2. Update version in docker-compose.yml
3. Pull new image: docker-compose pull
4. Recreate container: docker-compose up -d
5. Verify everything works
6. Keep backup until confident in new version

Using latest (Not Recommended)

Only use latest if you:

• Are testing/development (not production)
• Want automatic updates (understand the risks)
• Have good backup/restore procedures
• Monitor for breaking changes in releases

Even then, consider using version tags for better control.

Docker CLI Commands

# Reset Password (when locked out)
docker exec -it subtrackr /app/subtrackr --reset-password

# Disable Authentication
docker exec -it subtrackr /app/subtrackr --disable-auth

🔄 Upgrade Instructions

Standard Installation

# Backup your data first (via Settings UI)
# Then pull the latest version
git pull
go build -o subtrackr ./cmd/server
./subtrackr

Docker (Pinned Version)

# 1. Backup your data first (via Settings UI)

# 2. Update docker-compose.yml to new version
#    image: bscott/subtrackr:v0.5.0

# 3. Pull new image
docker-compose pull

# 4. Recreate container
docker-compose up -d

# 5. Verify logs
docker-compose logs -f subtrackr

⚙️ Technical Details

• Zero Breaking Changes - Authentication is OFF by default
• Backward Compatible - Existing installations work without modification
• Session Secret - Auto-generated 64-byte random key stored in database

SubTrackr v0.4.6 Release Notes

🎉 Overview

This release focuses on Docker improvements and CI/CD pipeline optimization. We've added Docker healthcheck support (Issue #47), simplified Docker image tagging, and optimized the build pipeline to only create images on Git tags.

  • 3-second timeout per health check
  • 5-second start period to allow application initialization
  • 3 retries before marking container as unhealthy
  • Uses curl to check /healthz endpoint with database connectivity verification
  • Verifies both HTTP server and database availability
  • Enables better container orchestration and monitoring

• Health Endpoint

  • New /healthz endpoint (Kubernetes convention)
  • Checks database connectivity in addition to HTTP server availability
  • Returns 200 OK with {"status": "healthy"} when healthy
  • Returns 503 Service Unavailable when database is unavailable

• Runtime Dependencies

  • Added curl to runtime dependencies for healthcheck support
  • Minimal impact on image size (~180MB total)

🔧 CI/CD Pipeline Improvements

• Simplified Docker Image Tagging

  • Only creates exact version tag (e.g., v0.4.6) and latest
  • Removed major and minor version tags (v0, v0.4)
  • Cleaner image registry with fewer redundant tags
  • Easier to identify specific versions

• Optimized Build Triggers

  • Docker images only build on Git tag pushes (v*)
  • Removed automatic builds on main branch pushes
  • Reduces CI/CD resource usage
  • Manual builds still available via workflow_dispatch
  • More efficient and cost-effective pipeline

🔧 Technical Improvements
