    4.3.7

  • Replace deprecated String.prototype.substr()

    4.3.4

  • The old organization was defunct and abandoned.

    4.3.3

  • I was not an owner of the old organization and thus could not ban the non-trivial amount of spam users or the few truly abusive users from the org. This hindered my ability to properly maintain this package.

    4.3.3

  • The debug ecosystem intends to grow beyond a single package, and since new packages could not be created in the old org (nor did it make sense for them to live there), a new org made the most sense - especially from a security point of view.

    4.3.3

  • The old org has way, way too many approved members with push access, for which there was nothing I could do. This presented a pretty sizable security risk given that many packages in recent years have fallen victim to backdoors and the like due to lax security access.

    4.3.3

  • Deprecated debugInstance.destroy(). Future major versions will not have this method; please remove it from your codebases as it currently does nothing.

    4.3.0

  • Replaced phantomJS with chrome backend for browser tests

    4.2.0

  • Deprecated and later removed Changelog.md in lieu of releases page

    4.2.0

  • Removed bower.json

    4.2.0

6 internal lines (docs, tests, tooling) left out.
