Often, the development branch is the trunk. Some revision control systems have specific jargon for the main development branch. For example, in CVS, it is called the "MAIN" branch. Git uses "master" by default, although GitHub [4] [5] and GitLab switched to "main" after the murder of George Floyd.
[1] [2] [3] Git, the world's most popular version control system, [4] is a distributed version control system. In 2010, software development author Joel Spolsky described distributed version control systems as "possibly the biggest advance in software development technology in the [past] ten years".

Git is a free and open-source software shared under the GPL-2.0-only license. Git was originally created by Linus Torvalds for version control during the development of the Linux kernel. [14] The trademark "Git" is registered by the Software Freedom Conservancy, marking its official recognition and continued evolution in the open-source community.
Version control (also known as revision control, source control, and source code management) is the software engineering practice of controlling, organizing, and tracking different versions in history of computer files; primarily source code text files, but generally any type of file.
In version control systems, a repository is a data structure that stores metadata for a set of files or directory structure. [1] Depending on whether the version control system in use is distributed, like Git or Mercurial, or centralized, like Subversion, CVS, or Perforce, the whole set of information in the repository may be duplicated on every user's system or may be maintained on a single ...
ClearCase can accommodate large binary files, a large number of files, and large repository sizes. It supports branching and labeling. It enables the correct merging of refactored files by versioning directories. It also supports extensive process automation and enforcement using triggers, attributes, hyperlinks, and other metadata.
Example history graph of a version-controlled project, with merges as red arrows. In version control, merging (also called integration) is a fundamental operation that reconciles multiple changes made to a version-controlled collection of files. Most often, it is necessary when a file is modified on two independent branches and subsequently ...
