Does Point-in-time (PIT) API available in OpenSearch 1.3.x?

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
OpenSearch 1.3.x

Describe the issue:

The guide Point in Time API - OpenSearch documentation says that OpenSearch 1.3.x has API for PIT, but release notes says - no, it available start from 2.4.0.

Is it documentation bug? Or 1.3 really has PIT feature.


Relevant Logs or Screenshots:

It’s a documentation bug, PIT is not available in 1.3.
