This has been an Elastic Search killer for me. I´m delighted about the performance and reliability. I will release soon a Python and PHP lib we developed internally for communicating with Vespa.\r\n\r\nBut one thing is missing for me is a changelog, and a upgrade guide so I can plan my deployment. What is the best practice ? Should keep continually upgrade Vespa? What If I upgrade my nodes a year from now, it will be a supported path ?\r\n\r\nThank you again for this awesome project!\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/vespa-engine/vespa/issues/comments/374112343","html_url":"https://github.com/vespa-engine/vespa/issues/5371#issuecomment-374112343","issue_url":"https://api.github.com/repos/vespa-engine/vespa/issues/5371","id":374112343,"user":{"login":"kkraune","id":8989061,"avatar_url":"https://avatars2.githubusercontent.com/u/8989061?v=4","gravatar_id":"","url":"https://api.github.com/users/kkraune","html_url":"https://github.com/kkraune","followers_url":"https://api.github.com/users/kkraune/followers","following_url":"https://api.github.com/users/kkraune/following{/other_user}","gists_url":"https://api.github.com/users/kkraune/gists{/gist_id}","starred_url":"https://api.github.com/users/kkraune/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/kkraune/subscriptions","organizations_url":"https://api.github.com/users/kkraune/orgs","repos_url":"https://api.github.com/users/kkraune/repos","events_url":"https://api.github.com/users/kkraune/events{/privacy}","received_events_url":"https://api.github.com/users/kkraune/received_events","type":"User","site_admin":false},"created_at":"2018-03-19T06:22:01Z","updated_at":"2018-03-19T06:22:01Z","author_association":"CONTRIBUTOR","body":"Hi, thanks for the nice words and thanks for contributing!\r\n\r\nFind details on Vespa versioning at http://docs.vespa.ai/documentation/vespa-versions.html. In short, take care when upgrading across major versions. Some more on the process itself: http://docs.vespa.ai/documentation/operations/live-content-cluster-upgrade.html (note to self: this doc needs to be freshened up)\r\n\r\nGenerally it is better to to smaller updates, often. This reduces risk of errors as changes are smaller - and you get access to new features. The APIs should let you build automation for this without too much work.\r\n\r\nWe do not keep a changelog, we try to use issues for the relevant changes, but I know this can be a bit hard to track.\r\n\r\nI will think a bit more about documentation for upgrades, thanks for the reminder"}}
