The Panoramic Survey Telescope And Rapid Response System-1 (Pan-STARRS-1, PS1) has been in full science operation since Spring 2010 and concluded the observing program for the PS1 Science Consortium (PS1SC) in early 2014. The Medium Deep Survey (MDS) component of the program regularly visited 10 fields (~7 sq. deg. each) with significant multi-wavelength overlap from previous and concurrent surveys (e.g. SDSS, DEEP2, CDFS, COSMOS, GALEX) for 25% of the total time allocation. The cadence generally includes the g,r,i,z filters for a MDS field every 3 days over the 6-8 month season the field is visible, with the y filter done primarily during bright time. The nightly stacks of eight exposures typically reach depths of r,i~23.5 mag. Development work continued to improve the single exposure processing though to deep stacks during the transient event discovery and other science consortium programs over the course of the survey, the culmination of those improvements being applied in a more uniformly reprocessed dataset used for the public data release. A summary of the MDS public data release products will be presented.
