Two main IUCLID releases are made per year: a major release, usually in April, and a service release in October. Two intermediate releases can also be published on the IUCLID website in addition to the two main releases. The IUCLID format is modified only in the major releases. The IUCLID instances hosted by ECHA in the ECHA Cloud Services are updated whenever new functionality becomes available, but the IUCLID format it uses changes only once a year.

The information below aims at highlighting the work planned for the web interface, particularly the remaining development to complete the transition from the IUCLID Classic interface to the web user interface. As such, this is not an exhaustive list, and is subject to change.
