Commit comments written by developers when they submit their changes to a
versioning system are useful for a number of tasks: Developers write commit
comments to document changes and as a means to communicate with the rest of the
development team; Researchers mine commit-related data contained in software
repositories to support software evolution and reverse engineering activities.
However, the support provided by IDEs is restricted in this respect, as they
limit the users to use only text to document their changes. We present Commit
2.0, an IDE enhancement to enrich commit comments using software visualization.
Commit 2.0 generates visualizations of the performed changes at different
granularity levels, and lets the user annotate them.
