the lastest version numbers have gone back in time

technically, the latest version (v2.0.0-alpha.7) is a lower version than v2.0.0 from March… in npm v3.10, this command installs v2.0.0:

$ npm i koa@^2.0.0-alpha

Only a mild annoyance, but "koa": "^2.0.0-alpha" in my package.json doesn’t install the latest release as desired.

The issue is valid, and actually has nothing to do with npm, it’s down to this project’s release management; the release/tag management of the project in github.

The project has a release 2.0.0 which is older than the latest 2.0.0-alpha.X releases.

This availability of release 2.0.0 supersedes 2.0.0-alpha.X releases, this is basic semver. Therefore anyone trying to install using semver 2.0.0-alpha.X will get the outdated 2.0.0 release and not the latest 2.0.0-alpha.X release.

The project should remove release 2.0.0 as it is not 2.0.0 due to 2.0.0-alpha.X tags still being released… see the release history.

(replace release w/ tag etc)

Sidenotes;

@75lb using ^2.0.0-alpha will install anything up to 3.0.0 – basic semver… your app could break at any time 😉

@jonathanong using next is a bit like using master, just slightly more controlled 😉

@jonathanong remove the “2.0.0” release tag… 😉
