			== Releases and pipelining ==
			Check the pipeline artifacts for the most recent generation outputs from out GitLab CI/CD pipeline and see whether the foundry you wanna target already had a Danube River generated and one in tapeout.

			As soon as we get more than just GF180, for which we don't even have all the data, we will start providing pages with tables of all the measurements.
