Blame

“Blame” (in git, or “annotate” in mercurial) is a feature to show the last revision that modified the line, for each line in a file. The blame information is embedded into the source listing.

Blame strip

The blame information is available from the blame strip, which is shown at the left side of the line numbers, as a gray line. Hovering a pointer over the blame strip shows a “blame popup”, which shows the blame information for the given chunk of the code.

The first two lines show the commit mssage, usually starts from the bug number, and then the author, and the author date (not the committer/push date).
