The Ed-Fi ODS/API version 3.3 has reached the end of support.
What Should I Do Now?
Please consider moving to a new version of the ODS/API for the next school year; see the Ed-Fi Technical Suite Version Matrix for a list of the supported options.
ODS/API version 3.3 implemented a "pre-release" version of the Ed-Fi Data Standard, specifically, version 3.2.0-a. ODS/API version 5.1 is the last release that supported Data Standard 3.2 (v3.2.0-c), and it is completely backward-compatible with respect to the Data Standard. Starting a new school year with ODS/API version 5.1 is a good option for those on older versions.
Alternately, you may wish to explore the changes in Data Standard 3.3 or Data Standard 4.0 to see if an even newer version of the ODS/API might be appropriate for your next school year.
