# Upgrade Guide

## Versioning Scheme

zCart versioning scheme maintains the following convention: `paradigm.major.minor`.

Minor Release: Minor releases should never contain breaking changes. This releases may contain bug fixes, UI issue fixes, minor improvements and new features.

Major Release: Major releases of zCart may include breaking changes sometimes. Read the upgrade guide carefully before starting the process. A major release may contain new features, third-party API upgrade, bug fixes and changes in zCart modules, etc.

Paradigm Shifting Releases: Paradigm shifting releases do include breaking changes and may represent fundamental shifts in the zCart’s architecture and conventions.

However, we strive to always ensure you may update to a new major release without having much trouble.
