New JWST spectra identify C3 as the carrier of the 5.2 um band, detect CS and HCN, link most changes to pulsation, and suggest some prior weak SiC dust reports may be spurious.

Second-epoch JWST/MIRI-MRS mid-IR spectra of SN 1987A show little overall dust evolution but inner equatorial ring fading, rapid ejecta line changes, some ER line fading, first mid-IR H2 from ejecta, and evidence that dense Fe-rich ejecta has reached the reverse shock.
