The document summarizes new software improvements in versions 6.5 and 6.5.1 of TCIA including making downloader installation files paths and names configurable, creating Linux installers for the TCIA downloader, and improving the downloader by providing a default download directory. It also discusses major upgrades for TCIA including installable downloader apps for Windows, Mac, and Linux that start automatically when a manifest file is opened in the browser and return manifest files that can be reused and shared for public collections. Future improvements will allow manifest files to also be shared for private collections according to individual user access rights.
