Git is a version control software that allows developers to track changes in the source code of their applications. It is the most popular version control system and is used by many open-source and commercial software projects. Git helps developers to coordinate their work and keep track of different versions of their code. It also enables developers to create branches and easily merge them into the main project. Additionally, Git enables developers to keep a log of changes and easily switch between different versions of the code. This makes it easier to debug and troubleshoot problems, as well as quickly revert to a previous version if needed.

The features don't seem to be upgraded, but instead, they all fit together well.
Easier to use, especially on Windows.
