@ashnur: proton should automatically keep them up to date

Alternatively open the package manager and check which ones are outdated

@dvcrn: it's interesting because when I put linter-eslint into additional-packages I will get the package with version 7.1.3 which should install eslint 2.4.0 as dependency, but it installs 2.2.0 instead

@ashnur: you don't need to put it in additional packages. If you activate the linter layer and javascript layer, it should install it automatically - https://github.com/dvcrn/proton/tree/master/src/cljs/proton/layers/lang/javascript

as for the version problem - hrm. You can try manually going into the eslint folder (in ~/.atom/) and force upgrade it
