Yes you are right, I was focused on releasing the `cti-python-stix2` dependencies, including `cti-pattern-validator` which was released at the same time, but forgot the pending changes on the validator.
We just released it today both on github and PyPi: https://pypi.org/project/stix2-validator/3.3.1/

Thanks, it's great to hear updates have resumed. Will stix2-validator also be updated in PyPi? It still lists the latest version as April 5, 2024 but on GitHub I see changes have been made this year.

Hi Jeffrey,
I think I mentioned it during the last CTI TC Meeting, but just to have the situation clarified here in the discussion, the latest update of the library has been published on PyPi earlier this year.
Thank you for bringing this topic onto the table, PyPi was indeed missing a lot of the recent updates to the library.
