VERSION "[major].[minor].[patch][-<pre>.<id>]"This is quite often left blank, but it is highly recommended to follow semantic versioning (semver) to keep track of your changes and progression between versions and releases.
Furthermore, I personally recommend that everyone make use of a version control system like Git to help you precisely track file changes, manage issues and bugs, among many other useful features. Companies such as GitHub and GitLab offer very generous free-tier memberships... you may find that most projects can subsist just fine using only a free membership. 😉
