Previously scoped only to the announcement, but apparently they cut off 'extra' version numbers, in this case the ".0" of "1.7.0". However, the download button includes the full, real version number.

For clarity and ease of use, at least for me, I've also switched to xmllint to get the version number now.

Output:
