Why was ISO10126 Padding Withdrawn? Wikipedia mentions ISO10126 Padding has been withdrawn, but doesn't say why. Also there were no news reports about this, as far as I can see.

Why was it withdrawn? Are there security flaws? Is there maybe a new version?
Indeed, ISO 10126-1:1991 and ISO 10126-2:1991 titled Banking -- Procedures for message encipherment (wholesale) have been withdrawn circa 2007.

The padding specified by ISO 10126 was adding random until the message has length 7 (mod 8) bytes, then adding a byte coding the number of bytes added (including that byte), making the length 0 (mod 8) and suitable for DEA/DES block encryption. The rationale for adding a little randomness is dubious at best; it creates a subliminal channel, for no clear advantage.

I conjecture that the rationale of the withdrawal is not the padding algorithm, but rather the use of single-DEA/DES (56 bit key), which is clearly obsolete and insecure; and availability of other standards for the same purpose.
