Can we get the release notes for the 2.1 version?
Also is there any way to modify the description of the artifact once it is deployed into the repository?
Please see: http://www.nabble.com/-ANN-Artifactory-2.1-p25796658.html
To your question - currently to change the content of an already-deployed pom, you have to redeploy it through the UI and use the inline editor, or edit it externally and redeploy via the UI or via HTTP.
You can also file a JIRA request for this to http://issues.jfrog.org.
Hope that helps,
