Doc: call out UPDATE syntax change as a v10 compatibility issue. The change made by commit 906bfcad7 means that if you're writing a parenthesized column list in UPDATE ... SET, but that column list is only one column, you now need to write ROW(expression) on the righthand side, not just a parenthesized expression. This was an intentional change for spec compatibility and potential future expansion of the possibilities for the RHS, but I'd neglected to document it as a compatibility issue, figuring that hardly anyone would bother with parenthesized syntax for a single target column. I was wrong, as shown by questions from Justin Pryzby, Adam Brusselback, and others. Move the release note item into the compatibility section and point out the behavior change for a single target column.
