Arduino Nano question

Hi there,

I am looking for the Arduino board for my school project and I have found that Nano version fits my needs perfectly, but I have found that this board is retired.

What does it mean? There is no support for that board or components won't be produced for it?

Can you please explain me this?

Here is the link where I have found the information:

Retired just means that Arduino is no longer making the Nano, however Nano clones are readily available for a low price. Since the Nano is very similar to the Uno, which is still in production and will be for a long time to come, the Nano is well supported and is an excellent choice due to its small size and breadboard friendly form.

Thank you!
