Programming Language Releases Dataset

Timeline of releases for five ecosystems: Go, Python/CPython, JavaScript (ECMAScript + Node.js), Kotlin and Rust. Each ecosystem is a separate config with its own Parquet file.

Loading

python
import datasets

for cfg in ("go", "python", "js", "kotlin", "rust"):
    ds = datasets.load_dataset("devoffeed/language-releases", cfg)
    print(cfg, ds["train"].num_rows, ds["train"].to_pandas().head(2))

Filter across everything:

python
import pandas as pd

          for c in ("go", "python", "js", "kotlin", "rust")]
all_df = pd.concat(frames, ignore_index=True)
print(all_df[all_df.release_type.isin(["major", "major"])].groupby("language").size())

Source data files (source/)

All curated content lives as standalone data files (no data inside code). The Parquet files under data/ are generated from them by a small assembler script.

Notes

  • —Go patch release_type is inferred from the official notes text (security when a security fix is mentioned), changes carries the official text.
  • —Per-version dates come from official/dist sources; status (support phases + EOL) from endoflife.date (python.org schedule).
  • —Compiled 2026-09-17.
