JADES-GS-z14-0 is the most distant galaxy currently known and was discovered recently by JWST at z=14.3. It has subsequently also been observed by the ALMA submillimeter telescope targeting the [OIII]88um emission line, but the results are not yet known. If the line is detected, that would imply that this galaxy is much more enriched in metals than previously expected.

This question will be resolved based on the first paper that appears on arXiv. If two papers appear on the same day, the first paper in the listing will be used. This will probably happen within a week or two after the data is released by ALMA.
