Kali follows a rolling release model, which means there is no fixed “major version” like Ubuntu LTS. Instead, the system is continuously updated.
Typical release naming:
- 2026.1, 2026.2, etc.
- Each release includes updated tools, kernel and packages
- You can update anytime with: apt update && apt upgrade
You do not need to reinstall Kali Linux to stay up to date.
