4.4.0

2024-12-06T12:37:31Z

Fixes (hopefully) the inefficient regex warnings in .enable().

Minor version as this is invariably going to break certain users who misuse the .enable() API and expected it to work with regexes, which was never supported nor documented. That's on you, sorry - that functionality won't be added back.

Repository Migration Information

I've formatted this as a FAQ, please feel free to open an issue for any additional question and I'll add the response here.

Q: What impact will this have on me?

In most cases, you shouldn't notice any change.

The only exception I can think of is if you pull code directly from https://github.com/visionmedia/debug, e.g. via a "debug": "visionmedia/debug"-type version entry in your package.json - in which case, you should still be fine due to the automatic redirection Github sets up, but you should also update any references as soon as possible.

Q: What are the security implications of this change?

If you pull code directly from the old URL, you should update the URL to https://github.com/debug-js/debug as soon as possible. The old organization has many approved owners and thus a new repository could (in theory) be created at the old URL, circumventing Github's automatic redirect that is in place now and serving malicious code. I (@Qix-) also wouldn't have access to that repository, so while I don't think it would happen, it's still something to consider.

Even in such a case, however, the officially released package on npm (debug) would not be affected. That package is still very much under control (even more than it used to be).

Q: What should I do if I encounter an issue related to the migration?

Search the issues first to see if someone has already reported it, and then open a new issue if someone has not.

Q: Why was this done as a 'patch' release? Isn't this breaking?

No, it shouldn't be breaking. The package on npm shouldn't be affected (aside from this patch release) and any references to the old repository should automatically redirect.

Thus, according to all of the "APIs" (loosely put) involved, nothing should have broken.

I understand there are a lot of edge cases so please open issues as needed so I can assist in any way necessary.

Q: Why was the repository transferred?

I'll just list them off in no particular order.

The old organization was defunct and abandoned.
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.
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.
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.

Q: Was this approved?

Yes.^[archive]

Q: Do I need to worry about another migration sometime in the future?

No.
