Changes in EAD3 v1.1.0 reflect feedback from the community since the initial EAD3 1.0.0 release in 2015. The EAD3 v1.1.0 release also represents a move towards a more agile schema maintenance plan in which smaller updates and fixes can be released on a more regular basis. In the next few months, TS-EAS will be working on documentation outlining this new incremental release process.
