After a long hiatus, we’re linking to merge commits again. We truncated merge commits months ago, because they didn’t provide any information beyond the shas of the parents, but now we’re exposing the diff between them as an overview of what changed in the branch.
Essentially, what we’re doing behind the scenes is: git diff parent1…parent2
This page will become the basis for a more extensive code review system that, coupled with our current code commenting, will really provide a lot of value for large projects.
(If older merge commits aren’t showing diffs, it’s most likely that it got cached without the additional data)
