The Australian SKA Pathfinder (ASKAP) is being used to undertake a campaignto rapidly survey the sky in three frequency bands across its operationalspectral range. The first pass of the Rapid ASKAP Continuum Survey (RACS) at887.5 MHz in the low band has already been completed, with images, visibilitydatasets, and catalogues made available to the wider astronomical communitythrough the CSIRO ASKAP Science Data Archive (CASDA). This work presentsdetails of the second observing pass in the mid band at 1367.5 MHz, RACS-mid,and associated data release comprising images and visibility datasets coveringthe whole sky south of declination $+$49$^\circ$. This data releaseincorporates selective peeling to reduce artefacts around bright sources, aswell as accurately modelled primary beam responses. The Stokes I images reach amedian noise of 198 $\mu$Jy PSF$^{-1}$ with a declination-dependent angularresolution of 8.1 to 47.5 arcsec that fills a niche in the existing ecosystemof large-area astronomical surveys. We also supply Stokes V images afterapplication of a widefield leakage correction, with a median noise of 165$\mu$Jy PSF$^{-1}$. We find the residual leakage of Stokes I into V to be$\lesssim$ 0.9 to 2.4 % over the survey. This initial RACS-mid data releasewill be complemented by a future release comprising catalogues of the surveyregion. As with other RACS data releases, data products from this release willbe made available through CASDA.
