The next day I would have to go and update that date, not very nice. I think it would be useful if I could simply put `resolver: nightly` and that would symbolically link to the latest nightly release.\r\n\r\nAnother disadvantage of always using the latest nightly release is that I would have to rebuild snapshot dependencies every day. This can be avoided by switching to a latest nightly snapshot once a week instead of once a day. It would be interesting to have something like `resolver: weekly` which would resolve to the latest Monday/Sunday snapshot.\r\n\r\nThat feature is quite arguable because at the moment there is no way that I know of to get an unreproducible build with stack (snapshot version has to be explicitly specified, package versions has to be explicitly specified) and that feature would introduce such a way.\r\n\r\nWhat do you think?"},"comment":{"url":"https://api.github.com/repos/commercialhaskell/stack/issues/comments/118116821","html_url":"https://github.com/commercialhaskell/stack/issues/390#issuecomment-118116821","issue_url":"https://api.github.com/repos/commercialhaskell/stack/issues/390","id":118116821,"user":{"login":"snoyberg","id":49415,"avatar_url":"https://avatars.githubusercontent.com/u/49415?v=3","gravatar_id":"","url":"https://api.github.com/users/snoyberg","html_url":"https://github.com/snoyberg","followers_url":"https://api.github.com/users/snoyberg/followers","following_url":"https://api.github.com/users/snoyberg/following{/other_user}","gists_url":"https://api.github.com/users/snoyberg/gists{/gist_id}","starred_url":"https://api.github.com/users/snoyberg/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/snoyberg/subscriptions","organizations_url":"https://api.github.com/users/snoyberg/orgs","repos_url":"https://api.github.com/users/snoyberg/repos","events_url":"https://api.github.com/users/snoyberg/events{/privacy}","received_events_url":"https://api.github.com/users/snoyberg/received_events","type":"User","site_admin":false},"created_at":"2015-07-02T18:27:53Z","updated_at":"2015-07-02T18:27:53Z","body":"I've added a comment to #115 about this issue, will continue tracking this there."}}
