In the past year, the development of ROOT I/O has focused on improving the existing code and increasing the collaboration with the experiments' experts. Regular I/O workshops have been held to share and build upon the varied experiences and points of view. The resulting improvements in ROOT I/O span many dimensions including reduction and more control over the memory usage, drastic reduction in CPU usage as well as optimization of the file size and the hardware I/O utilization.
