What do these upgrades mean for you? 
Keeping up with Umbraco CMS releases is essential for security, performance, and new features. However, you don’t necessarily need to invest in every single upgrade. Here’s a practical approach:
1. Understand Umbraco’s Release Cycle
Umbraco follows a structured release cycle:
- Patch releases (frequent, e.g., 13.1, 13.2): Small updates with bug fixes and security improvements.
- Minor releases (every 6 weeks, e.g., 14.0 to 14.1): New features but backward-compatible.
- Major releases (yearly, e.g., 13.x to 14.x): Can include breaking changes, requiring more effort to upgrade.
At Element 78, as part of our proactive support package, we work closely with client to advise and prioritise security and patch updates and plan for minor and major upgrades strategically in line with the website and business strategy.
2. Upgrade Strategy
- Patch releases → Always update as soon as possible. They don’t break existing functionality.
- Minor releases → Upgrade if you need the new features or bug fixes, but not always necessary immediately.
- Major releases → Evaluate whether the new version’s benefits outweigh the effort to upgrade. You may need development resources for breaking changes.

3. Use Long-Term Support (LTS) Versions
If your website is on an LTS version (e.g., Umbraco 12 LTS, 13 LTS), it will receive bug fixes and security updates for a longer time. This gives you more time to plan major upgrades.
4. Budget for Periodic Upgrades
If you're on an older version (e.g., Umbraco 8 or 9), upgrading may require a rebuild. Instead of waiting for years, schedule an upgrade every 1-2 years to keep up with modern technology without a massive investment all at once.
