versieconstraints

Versieconstraints are rules that specify which versions of a software library or component are considered acceptable for use by a project. They are a core part of dependency management, ensuring compatibility and stability while allowing for controlled updates. A constraint can express an exact version, a minimum or maximum version, or a range of acceptable versions. In many ecosystems constraints are written in configuration files and interpreted by a package manager during install or build.

Examples of constraints include an exact version such as 2.3.1; a minimum version such as >=2.0.0; an upper bound such as <3.0.0; or a range such as >=1.2.0 and <2.0.0. In semantic versioning based ecosystems there are additional forms such as caret and tilde ranges, for example ^1.2.3 or ~1.2.3, which define broader but still controlled sets of versions.

Versieconstraints interact with transitive dependencies, which are dependencies of dependencies. The package manager must resolve a set of versions that satisfies all constraints; conflicts can occur if two dependencies require incompatible versions. This can be mitigated by using lockfiles to pin exact versions for reproducible builds and by periodically updating constraints with testing.

Practices include favoring permissive but safe ranges, avoiding overly strict constraints that block minor improvements, and reviewing major version changes carefully before upgrading. Common related concepts include semantic versioning, dependency resolution, and lockfiles.
