Appendix: Notes on changes in the infrastructure
The preceding article details only a selection of the most significant changes, the proverbial tip of the iceberg, that have been made with the release of 2.6.28. In the main branch of the source code management system, there are thousands of commits, representing many other changes. In this appendix, we categorise and list some of the less significant, but still important changes. Each entry has a link to the source code management system, where more detailed information and background to each committed patch can be found.
