The following is a cumulative list of enhancements and major bug fixes in each Optimizely Web Experimentation release. Because Optimizely Web Experimentation releases new features and fixes as soon as they are ready, this list will update regularly.

## October

Removed the ability to target audiences by platform/OS version because of user-agent reduction. See [Set up audiences in Optimizely: Audience Builder](docId\:tSoFLwt3tc93lZ30vPaLd).

## August

Added Concurrent Editing, which notifies you when other collaborators are working on the same experiment. See [Collaborate efficiently with Concurrent Editing](docId\:Uv1qXtrvUVdoI3gBTKRu-).
