We present an updated collection of eclipsing and ellipsoidal binary systems in the Large and Small Magellanic Clouds (LMC and SMC), as observed by the Optical Gravitational Lensing Experiment (OGLE) survey. The catalog comprises a total of 75\,400 binary systems, including 63 252 in the LMC and 12 148 in the SMC. The sample is categorized into 67 971 eclipsing and 7429 ellipsoidal variables. For all stars, we provide I-band and V-band photometric time series collected between 2010 and 2024 during the fourth phase of the OGLE project (OGLE-IV). We discuss methods used to identify binary systems in the OGLE data and present objects of particular interest, including double periodic variables, transient eclipsing binaries, double eclipsing binaries, and binary systems with pulsating stars. We present a comparative analysis based on the most comprehensive catalogs of variable stars in the Magellanic System, compiled from surveys like Gaia, ASAS-SN, and EROS-2, and included in the International Variable Star Index.
