V15

V15 is a release tag used in versioning systems to label a particular state of a product, most commonly software, firmware, or hardware. The prefix v, short for version, combined with a number signals an iteration in a project's development timeline. In many projects, v15 denotes the fifteenth major release or generation, though the exact meaning is project-specific and may reflect sequence rather than a fixed milestone.

Versions labeled v15 can appear in several formats, such as v15, v15.0, or v15.0.1, depending on the project’s numbering scheme. Some projects follow semantic versioning and include major, minor, and patch components, while others use a simpler or different scheme. Pre-release or build metadata may accompany the tag, using suffixes like -alpha, -beta, -rc, or +build, but not all projects apply these distinctions. It is also common for some projects to omit the v prefix or to use solely a numeric label without leading characters.

Releases tagged v15 typically come with release notes outlining new features, improvements, bug fixes, performance changes, and potential API or compatibility considerations. Upgrade paths and migration guidance are often provided, as breaking changes or deprecated features may affect users and downstream projects.

V15 is widely used across domains, including open-source libraries and frameworks, mobile and desktop applications, operating systems and kernels, firmware for devices, drivers, and APIs. Its specific implications—such as feature sets or compatibility—depend on the individual project and its versioning policy.
