Angular Versioning

Angular version numbers have three parts: major.minor.patch. For example, version 7.2.11 indicates major version 7, minor version 2, and patch level 11.

Major releases contain significant new features, some but minimal developer assistance is expected during the update.

Minor releases contain new smaller features.

Patch releases are low risk, bug fix releases.
