Semantic versioning communicates the significance of releases through MAJOR.MINOR.PATCH numbers. Major versions signal breaking changes, minor versions add backward-compatible capabilities, and patch versions fix bugs. section 9.4.2
Used consistently, the convention helps developers judge upgrade risk while APIs evolve. Breaking changes include removing response fields, requiring previously optional fields, changing validation rules, or modifying endpoint URLs. When possible, add new behavior alongside the existing interface and keep deprecated methods available long enough for migration. section 9.4.2
Reading a release number
A release moving from 1.4.2 to 2.0.0 communicates a breaking change. A move from 1.4.2 to 1.5.0 communicates a backward-compatible addition, while 1.4.3 communicates a bug fix. Deprecation warnings and replacement guidance give users a practical migration path before an older interface is removed. section 9.4.2
