Deprecate all versions prior to 4.x

Users should be warned that their setups will we soon broken with new Node.js releases.

This means to push a patch release to 1.x, 2.x, and 3.x branches.
Something similar to what lodash does:

npm WARN deprecated [email protected]: lodash@<3.0.0 is no longer maintained. Upgrade to lodash@^4.0.0.
npm WARN deprecated [email protected]: lodash@<3.0.0 is no longer maintained. Upgrade to lodash@^4.0.0.

Tracking issue: nodejs/node#5213

Proposed solution:
add

  "deprecated": "graceful-fs@<4.0.0 is deprecated and will be broken on newer Node.js versions. Upgrade to graceful-fs@^4.0.0 or later.",

to package.json of v2.1.0 and v3.0.8 and publish those as v2.1.1 and v3.0.9.

Thanks for the suggestion. I'll do this when I get to a computer.

Just so you know, and for posterity, editing package.json and publishing a new version is not the best way to deprecate a package. Deprecation should be done using the npm deprecate command.

@isaacs Ah, I wasn't aware that it is possible to that way, thanks!

[isaacs]

Done.

npm deprecate "graceful-fs@<4.0.0" "graceful-fs version 3 and before will fail on newer node releases. Please update to graceful-fs@^4.0.0 as soon as possible."
