A tool for providing a version controller bulletin. The tool retrieves metadata from a plurality of version controller repositories in a development environment. The tool creates one or more snapshots for the metadata over a pre-determined period of time, wherein the pre-determined period of time includes a start time and an end time. The tool determines a metadata difference between non-code related issue clusters of the one or more snapshots. The tool determines a confidence to conflict value and a line of code range for code related issue clusters of the one or more snapshots, wherein the confidence to conflict value represents a probability of a merge conflict. The tool provides respective heat maps for code related issue clusters and non-code related issue clusters. The tool outputs to a version controller bulletin, the metadata difference, the confidence to conflict value, respective heat maps, and the line of code range.

Version controller bulletin
