A changelog is a file that lists all the notable changes made to a project in a chronological order. It is often organized by version, with each version containing a list of added, improved, and removed features. Changelogs are essential for both users and developers to understand the evolution of a project
1.Simple Method to Generate a Changelog

To generate a basic changelog, you can use the git log command. This command displays a list of all your commits. Here are some useful variations of the git log command to format the output for a changelog:

Basic Log Command:

git log

One Commit Per Line:

git log --oneline --decorate

Custom Format:

git log --pretty="%s"

List Format:

git log --pretty="- %s"

You can redirect the output to a file to create a changelog:

git log --pretty="- %s" > CHANGELOG.md

Sophisticated Method to Generate a Changelog

For a more advanced and stylized changelog, you can use tools like generate-changelog available on NPM. This tool requires you to follow a specific commit message format, such as "type(category): description [flags]". Here’s how to use it:
