This is a replication package for the paper "The Impact of Code Review on Architectural Changes", to be published at the IEEE Transactions on Software Engineering (TSE). The TSE paper mentioned above is a journal extension of a previous conference paper published at the IEEE/ACM International Conference on Automated Software Engineering (ASE'17). Hence, this is also the replication package for our conference paper "Are Developers Aware of the Architectural Impact of Their Changes?" The replication package is composed of: 1 - 103,778 structural architectures extracted from the source code of 7 open source software systems. 2 - Churn and size metrics for each of the extracted structural architectures. 3 - Values of structural cohesion and coupling computed for the significant architectural changes 4 - A manual classification of the changes' intent The presented dataset can be used not only to replicate the TSE paper but also to perform new empirical studies involving software architecture, architectural changes, software changes, code review and software module clustering, to mention a few.
