New Personal Access Token Format

Greetings - I have an app that uses a few employee personal access token, most of them were created roughly a year ago.

They use this format (note: the PAT below is taken from the documentation page)

PAT from docs:

0/68a9e79b868c6789e79a124c30b0

However, when I create a PAT, it uses a different format:

1/xxxxxxxxxxxxxx:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

1/14digits:32characters

Is this a new format?
