What is the difference between a build and a release?

Build - is a compiled, assembled, and packaged version of software at a specific point in time. It may be incomplete, contain errors, and is used for internal testing.

Release - is the final, tested, and approved version of software, ready for delivery to end-users or deployment in production. It goes through several testing and quality control stages.

Key differences:

Attribute	Build	Release
Status	Intermediate version	Final version
Purpose	Testing, internal development	User release / production deployment
Quality	May contain errors	Stable, tested version
Availability	Usually for the development team	For a wide audience or deployment
Versioning	May have a temporary build number	Has an official version number
