  The Large and Small Magellanic Clouds (LMC and SMC) are the largest satellite
galaxies of the Milky Way and close enough to allow for a detailed exploration
of their structure and formation history. The Survey of the MAgellanic Stellar
History (SMASH) is a community Dark Energy Camera (DECam) survey of the
Magellanic Clouds using $\sim$50 nights to sample over $\sim$2400 deg$^2$
centered on the Clouds at $\sim$20% filling factor (but with contiguous
coverage in the central regions) and to depths of $\sim$24th mag in $ugriz$.
The primary goals of SMASH are to map out the extended stellar peripheries of
the Clouds and uncover their complicated interaction and accretion history as
well as to derive spatially-resolved star formation histories of the central
regions and create a "movie" of their past star formation. Here we announce the
second SMASH public data release (DR2), which contains all 197 fully-calibrated
DECam fields including the main body fields in the central regions. The DR2
data are available through the Astro Data Lab hosted by the NSF's National
Optical-Infrared Astronomy Research Laboratory. We highlight three science
cases that make use of the SMASH DR2 data and will be published in the future:
(1) preliminary star formation histories of the LMC; (2) the search for
Magellanic star clusters using citizen scientists; and, (3) photometric
metallicities of Magellanic Cloud stars using the DECam $u$-band.
