majorrelease

Majorrelease is a term used in software development to denote a release that introduces substantial changes that may not be backward compatible with earlier versions. In common versioning schemes, a major release corresponds to a major version increment (for example, moving from 1.x.y to 2.x.y). Major releases typically add new features, redesign components, or remove or alter APIs, data formats, or configuration options. Because of these changes, software and dependent integrations may require code updates, data migrations, or configuration changes to operate with the new version. This contrasts with minor releases, which add backward-compatible features, and patch releases, which address bugs without changing behavior.

The process surrounding a major release often involves extensive planning, impact analysis, deprecation notices, and migration guidance. Release notes document breaking changes, migration steps, and compatibility considerations. Many organizations perform staged rollouts, provide adapters or shims to ease transitions, and publish long-term support plans for selected major versions.

Impact: For developers, major releases require assessing API/ABI changes, updating dependencies, and updating integration points. For operators and end users, upgrades can entail rebuilding workflows, updating configuration, and testing in staging environments before production adoption. Versioning conventions such as semantic versioning help signal the nature of changes, but the precise impact depends on the product and ecosystem.

Note: While commonly used in software libraries, the concept of a major release applies to apps, frameworks, platforms, and other products that evolve with backward-incompatible changes.
