Semantic Versioning
A widely adopted software versioning specification that uses the format MAJOR.MINOR.PATCH. The three components correspond to three levels of change: incompatible API modifications, backward-compatible new functionality additions, and backward-compatible bug fixes respectively.
Core Facts
Patch versions typically contain only backward-compatible bug fixes and do not introduce breaking changes or new features.
Semantic versioning (SemVer) uses the format major.minor.patch, where an increment in the patch version indicates a backwards-compatible bug fix.
Patch-level updates generally do not introduce breaking changes and can typically be applied directly without modifying existing code.
Timeline (last 90 days)
SemVer is only a convention rather than a mandatory standard, and in actual projects there can still be cases where the PATCH position introduces behavior changes.
Backward compatibility only guarantees that old interfaces will not be removed or have their semantics changed; new features themselves may require actively calling newly added API methods to take effect.
The SemVer convention is the foundational rule by which package managers such as npm and yarn automatically resolve dependency ranges (e.g., ^1.0.0).
In SemVer, a MAJOR change indicates the introduction of incompatible breaking changes, while a MINOR change indicates backward-compatible feature additions.
It should not be assumed that changes during the 0.0.x stage are safe simply because the patch number has incremented.
Semantic Versioning (SemVer) divides version numbers into three segments — MAJOR.MINOR.PATCH — where a patch version increments only the last digit.
During the 0.0.x stage, even a patch number increment may introduce breaking changes.
For package.json files that depend on 0.0.x versions, it is not recommended to use loose version ranges such as ^ or ~; instead, exact version numbers should be used to avoid pulling in incompatible updates.
According to SemVer convention, a patch version contains only backward-compatible bug fixes or internal dependency adjustments and introduces no breaking changes, so existing users can upgrade directly with relative confidence.
Using semantic version range locking in package.json (e.g., ^3.0.0 rather than an exact version) can maintain flexibility while reducing the risk of accidentally introducing breaking changes.

90%VerifiedSemantic versioning (SemVer) defines version numbers as a three-part MAJOR.MINOR.PATCH structure, where PATCH changes include only backward-compatible bug fixes or dependency updates.
90%VerifiedPatch version updates theoretically contain no breaking changes, making the upgrade risk low.
90%VerifiedPatch releases typically contain backward-compatible bug fixes and do not change the behavior of existing APIs.
90%VerifiedPatch versions typically do not introduce breaking changes and are primarily used for bug fixes, performance optimizations, or syncing underlying dependencies, in compliance with Semantic Versioning (SemVer) specifications.
90%VerifiedThe Semantic Versioning (SemVer) format is MAJOR.MINOR.PATCH: a change in the major version number indicates backward-incompatible API changes, a change in the minor version number indicates new features that maintain backward compatibility, and a change in the patch number includes only bug fixes.
90%VerifiedThe Semantic Versioning format is MAJOR.MINOR.PATCH: MAJOR is incremented for incompatible API changes, MINOR is incremented when backward-compatible new features are added, and PATCH is incremented for backward-compatible bug fixes.
90%VerifiedThe version number format of the Semantic Versioning specification (SemVer) is MAJOR.MINOR.PATCH, where the PATCH version is specifically used for backward-compatible bug fixes.
90%VerifiedAccording to the Semantic Versioning (SemVer) specification, a Patch-level update signifies backward-compatible bug fixes.
90%VerifiedPatch-level updates typically contain bug fixes, dependency synchronization, or minor optimizations rather than breaking changes, and production environment teams can generally upgrade safely.
85%VerifiedAccording to the Semantic Versioning specification, 1.0.3 as a patch version means the update will not introduce breaking changes, and existing projects can safely upgrade.
85%VerifiedThe SemVer format is MAJOR.MINOR.PATCH, where MAJOR indicates breaking changes that are not backward compatible, MINOR indicates new features that are backward compatible, and PATCH indicates backward-compatible bug fixes
80%VerifiedThe Semantic Versioning specification (SemVer) defines version numbers as a three-part MAJOR.MINOR.PATCH structure, where a PATCH increment indicates a backward-compatible bug fix, MINOR indicates backward-compatible new features, and MAJOR indicates breaking changes.
80%VerifiedThis patch-level update maintains backward compatibility, allowing existing projects to upgrade without modifying their code.
80%VerifiedUnder the SemVer specification, when the major version number is 0, it means the project has not yet entered a stable public API phase and provides no backward compatibility guarantees
75%VerifiedIn semantic versioning, a major version number of 0 (e.g., 0.1.7) conventionally indicates that the public API is not yet stable and may change in a non-backward-compatible manner at any time.
75%VerifiedIn Semantic Versioning (SemVer), a patch version increment is strictly limited to backward-compatible bug fixes, introducing no new features and making no changes to the public API.
75%VerifiedIt is recommended that developers lock to explicit version numbers or use compatibility ranges in production environments to avoid unexpected behavior introduced by frequent updates.
