CARTA, Cube Analysis and Rendering Tool for Astronomy, is a new generation of image viewer for visualizing large images from telescopes such as ALMA, VLA, MeerKAT, and ASKAP. The core design philosophy is to ensure scalability for the future telescopes and to provide best user experience. In this poster presentation, we update the community with the development progress since ADASS XXIX. The latest release is v1.4 (September 2020) which includes a number of practical functions and tools for common use cases.
