This project provides this functionality by letting you see what\nversions were available in the past, when they were available, what revision to install them from, and what command to use.\n\nThe list of versions available here is not exhaustive. To check what versions of packages were ever available data\nwas collected from past revisions in 5 weeks intervals. This means that if a package changed versions more often\nthan every 5 weeks there may be versions missing.\n\nDuring the retrieval of version information, revisions for some periods could not be successfully built for\nsome channels and this could also cause versions to be missing from the list.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flazamar%2Fnix-package-versions","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flazamar%2Fnix-package-versions","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flazamar%2Fnix-package-versions/lists"}
