Beautiful

I think we called this a minor when we did it for .md #9755

and I guess https://semver.org/ specifies that when you add functionality it becomes a minor, but this could be seen as simply fixing a bug where ./ was incorrectly required as the syntax without ./ should have always been valid

1. MAJOR version when you make incompatible API changes
2. MINOR version when you add functionality in a backward compatible manner
3. PATCH version when you make backward compatible bug fixes

What do you think @rishi-raj-jain?

@OliverSpeir

Appreciate the thorough review. Does make sense.

add functionality it becomes a minor

I think I still need to learn where to mark it as a minor / patch as sometimes I just end up confusing between them. The PR can be seen as fixing a bug because it's "expected" to be able to use the paths without slashes, or be seen as an added functionality from the creators perspective.

The PR can be seen as fixing a bug because it's "expected"

A good way to understand that is if the docs mention this feature. If not, than it's not a bug. In fact, why don't we update the docs to show the new feature?

@rishi-raj-jain I ask you the following tasks, if you don't mind:

• update the test section of the template, and tell us how you tested the feature. Ideally, we want to add a new test
• update the docs section of the template, and link the docs PR where we add a new example
