After more than 40 years of life, software evolution should be considered as a mature field.
However, despite such a long history, many research questions still remain open, and …

Source control repositories, bug repositories, archived communications, deployment logs,
and code repositories are examples of software repositories that are commonly available for …

The ability to evolve software rapidly and reliably is a major challenge for software
engineering. In this introductory chapter we start with a historic overview of the research …

This chapter surveys a sample of empirical studies of Open Source Software (OSS)
evolution. According to these, the classical findings in proprietary software evolution, such …

The build system of a software project is responsible for transforming source code and other
development artifacts into executable programs and deliverables. Similar to source code …

Software development is undergoing a major change away from a fully closed software

We use 810 versions of the Linux kernel, released over a period of 14years, to characterize
the system's evolution, using Lehman's laws of software evolution as a basis. We investigate …

Change is an essential characteristic of software development, as software systems must
respond to evolving requirements, platforms, and other environmental pressures. In this …

Many open source projects have long become commercial. This paper shows just how much
of open source software development is paid work and how much has remained volunteer …

To evaluate the code generation capabilities of Large Language Models (LLMs) in complex
real-world software development scenarios, many evaluation approaches have been …
