JIRA mentions that 5.1.0.Beta1 should be available on March 16. However, JIRA also shows that 84 out of 122 issues are resolved. Do you think that March 16 is still realistic? I need an approx. date for scheduling whether to go for 5.1 or stay with 5.0.1. Thank you in advance.
Gee, you are living on the bleeding edge :) When looking at JIRA issues take note to consider only the critical/blocker ones. We often push non critical issues to a next release if they don't make the cutoff date (code freeze).
