Changes are classified by significance level, and the decision of which sequence to change between releases is based on the significance of the changes from the previous release, whereby the first sequence is changed for the most significant changes, and changes to sequences after the first represent changes of decreasing significance.ĭepending on the scheme, significance may be assessed by lines of code changed, function points added or removed, the potential impact on customers in terms of work required to adopt a new version, risk of bugs or undeclared breaking changes, degree of changes in visual layout, the number of new features, or almost anything the product developers or marketers deem to be significant, including marketing desire to stress the "relative goodness" of the new version. In some schemes, sequence-based identifiers are used to convey the significance of changes between releases. This is the extent of the commonality schemes vary widely in areas such as the number of sequences, the attribution of meaning to individual sequences, and the means of incrementing the sequences.

In sequence-based software versioning schemes, each software release is assigned a unique identifier that consists of one or more sequences of numbers or letters. Sequence-based identifiers An example version number sequence The ubiquity of computers has also led to these schemes being used in contexts outside computing. Schemes Ī variety of version numbering schemes have been created to keep track of different versions of a piece of software. Thus the numbering scheme needed to tell which version was newer than the required one. To facilitate upgrades, minimum package versions were introduced.

When installing a package, dependency resolution was used to automatically calculate the packages needed as well, and install them with the desired package. From 1994 on this idea was reverted, so a package that knew the packages it needed. Debian's first try was that a package knew other packages which depended on it. Linux distributions like Debian, with its dpkg, early on created package management software which could resolve dependencies between their packages. Later lists of files including their versions were added, and dependencies amongst them. For computer files this practice was introduced for the first time with MIT's ITS file system, later the TENEX filesystem for the PDP-10 in 1972. Modern computer software is often tracked using two different software versioning schemes: an internal version number that may be incremented many times in a single day, such as a revision control number, and a release version that typically changes far less often, such as semantic versioning or a project code name.įile numbers were used especially in public administration, as well as companies, to uniquely identify files or cases. At a fine-grained level, revision control is used for keeping track of incrementally-different versions of information, whether or not this information is computer software, in order to be able to roll any changes back.
Within a given version number category (e.g., major or minor), these numbers are generally assigned in increasing order and correspond to new developments in the software. Software versioning is the process of assigning either unique version names or unique version numbers to unique states of computer software.
