ReleaseEval: A Benchmark for Evaluating Language Models in Automated Release Note Generation

Qianru Meng, Zhaochun Ren, Joost Visser


Abstract
Automated release note generation aims to reduce the cost of documenting frequent software updates. Existing benchmarks mainly rely on commit messages, limiting evaluation of how models use broader software-change evidence. We introduce ReleaseEval, a reproducible and openly licensed multi-granularity benchmark with 94,987 release notes from 3,369 repositories across six programming languages. Each release is aligned with commit messages, commit tree structures, and raw code diffs, supporting three task settings: commit2sum, tree2sum, and diff2sum. Automatic and human evaluations show that models benefit from lightweight commit-tree structure, while raw diffs remain challenging due to length and noise. These findings position ReleaseEval as a multi-granularity benchmark for studying release note generation. We release the dataset and code at https://github.com/Changanyuexia/rn_benchmark/
