Very interesting article, thanks ! I think that CalVer is indeed super clear and brings directly information without even opening the product website to know if you’re up-to-date. Jetbrains is also using it for a while and it’s very convenient.
Just a small misleading typo here: “As of February 2019, CockroachDB has switched from Symantec Versioning to Calendar Versioning.” Semantic, right ?
