Version 15 of MapInfo Pro 32 bit was released in June 2015 and 64 bit (15.2) was released in October 2015. Highlights include geopackage support as well as changes to the TAB file format to allow larger files and Unicode. The 64 bit version of 15.2 saw the introduction of MapInfo Pro Advanced as a new licensing level for the product which incorporates all new raster capabilities into the product including a .NET SDK. MapInfo Pro Advanced allows users to visualize very large raster files at high resolution such as 1m for a whole country and incorporating multiple satellite bands. This is achieved using a new multi resolution raster file format (.mrr).
