Answer

What changed in ISO/IEC 18033-7 Amendment 1?

Not public yet. ISO records the amendment at stage 40.60 with no abstract, so no clause change can be stated. This page will state the changes from the published text, not from a draft or a rumour.

Why the answer is short

The amendment body is not public. The ISO record gives a designation, a stage, a page count and a price, and no abstract. There is no published list of changes and no clause text to compare with the base standard.

What we do instead of guessing

The record maps the base standard clause by clause, states the amendment s status, and marks every field where the amendment is silent. The paid register is built to be reissued when the text publishes, and kit buyers receive the reissue at no extra charge. If a security target or a datasheet cites the standard, the version in that claim is the item to review first.

How the comparison will work

On publication we will compare the amendment with the public base text, clause by clause, and list added, changed and removed requirements with the citation. Until then the honest answer is that the changes are not stated in the public preview.

Check it yourself

The record is on the publication page. The base text is mapped on the contents page. The free check turns the answer into a dated decision record.
