One idea would be to do something like It does collate the notes and put it in the cover letter, or at least it should. > > Series-changes 12: > * Summary of the below changes > - Small change > - Move foo to bar.c > - Reformat code to do baz > * Fix bug where device caught fire > > Where only lines beginning with '*' would be included in the combined > changelog.

Perhaps the clearest thing is to have: Series-changes: (behaviour as now) Commit-changes: (change log just in the commit/patch, not repeated in the cover letter) Cover-changes: (change log just in the cover letter) This should minimise duplication and makes the scheme optional. > > One last option could be to do something like > > Summary-changes 12: > - Summary of below changes > - Fix bug where device caught fire > > Where those changes would be included in the cover letter, but not > Series-changes.

Can we hold off until we figure out what we definitely want? Regards, Simon
