We release the next installment of the Stripe 82 X-ray survey point-sourcecatalog, which currently covers 31.3 deg$^2$ of the Sloan Digital Sky Survey(SDSS) Stripe 82 Legacy field. In total, 6181 unique X-ray sources aresignificantly detected with {\it XMM-Newton} ($>5\sigma$) and {\it Chandra}($>4.5\sigma$). This catalog release includes data from {\it XMM-Newton} cycleAO 13, which approximately doubled the Stripe 82X survey area. The flux limitsof the Stripe 82X survey are $8.7\times10^{-16}$ erg s$^{-1}$ cm$^{-2}$,$4.7\times10^{-15}$ erg s$^{-1}$ cm$^{-2}$, and $2.1\times10^{-15}$ ergs$^{-1}$ cm$^{-2}$ in the soft (0.5-2 keV), hard (2-10 keV), and full bands(0.5-10 keV), respectively, with approximate half-area survey flux limits of$5.4\times10^{-15}$ erg s$^{-1}$ cm$^{-2}$, $2.9\times10^{-14}$ erg s$^{-1}$cm$^{-2}$, and $1.7\times10^{-14}$ erg s$^{-1}$ cm$^{-2}$. We matched the X-raysource lists to available multi-wavelength catalogs, including updated matchesto the previous release of the Stripe 82X survey; 88\% of the sample is matchedto a multi-wavelength counterpart. Due to the wide area of Stripe 82X and richancillary multi-wavelength data, including coadded SDSS photometry,mid-infrared {\it WISE} coverage, near-infrared coverage from UKIDSS and VHS,ultraviolet coverage from {\it GALEX}, radio coverage from FIRST, andfar-infrared coverage from {\it Herschel}, as well as existing $\sim$30\%optical spectroscopic completeness, we are beginning to uncover rare objects,such as obscured high-luminosity AGN at high-redshift. The Stripe 82X pointsource catalog is a valuable dataset for constraining how this population growsand evolves, as well as for studying how they interact with the galaxies inwhich they live.
