Each line above is one paragraph there: what broke, how it was measured, and what was deliberately left alone. Written out in full on purpose — for anyone debugging the same thing, and so a summary of this release can be made from the reasoning rather than from the headline.

If you have attached a diagnostics file to a public issue

The fix above stops three credential keys reaching that download. It does not reach a file you have already posted, so if your entry signs in through volkswagen.de, sign out there and sign in again — that invalidates the cookie jar that was in the file. If you have Tibber connected, rotate that token. And delete the comment carrying the attachment: editing it leaves the earlier revision readable.

There is no sign that anyone has used any of this. The problem is that the file was readable by anyone, and that the integration asked you to post it. Details and the per-key specifics are in #923.
