From: Henry Saputra To: "dev@flink.incubator.apache.org" Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable X-Virus-Checked: Checked by ClamAV on apache.org Hi M=C3=A1rton, Yes, we could and should move to non-incubating repo. I think Robert and Stephan are working with Infra to make it happen. My question is more should we wait till migration happen or should we publish non-incubating release artifact to ASF diet and mvn central from our incubating source repository instead. - Henry On Mon, Jan 5, 2015 at 2:37 PM, M=C3=A1rton Balassi wrote: > I assume that infra graduation means that we can move to the non-incubati= ng > repo as well. > > Also to the best of my knowledge the release is not connected to the > incubating repo itself.
