Retag x509-cert

I am trying to use x509-cert-0.3.0-rc.0 and it is unable to be built due to errors. These errors have been resolved in commit #1889 but they are not included in this release. 
Can you retag or put out another release that includes these changes?
This also will require a retag/new tag for all the crates changed in commit #1889 
Thanks
