pretty_name: Programming Language Releases Dataset

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.

config	rows	coverage	source
go	290	Go 1.0 (2012-03-28) → Go 1.27.1 (2026-09-01), all majors + all patches	go.dev release history
python	66	Python 3.0.0 (2008-12-03) → 3.14.7 (2026-08-05) + 3.15 (planned 2026-10-01), majors + active patches + series finals	python.org downloads, endoflife.date
js	80	ECMAScript ES5 (2009) → ES2026 / ES2027 draft; Node.js 0.10 → 26.9.0 (full 24.x + 26.x history)	ECMA-262 (TC39), nodejs.org dist index
kotlin	30	Kotlin 1.0.0 (2016-02-15) → 2.4.20 (2026), all majors 1.0 → 2.4 + latest patches	endoflife.date, kotlinlang.org
rust	103	Rust 1.0.0 (2015-05-15) → 1.98 (2026-08-20): editions 2015/2018/2021/2024 + every 1.x release + patches	endoflife.date, blog.rust-lang.org

Loading

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:

import pandas as pd
frames = [pd.read_parquet("hf://datasets/devoffeed/language-releases/data/%s/train-00000-of-00001.parquet" % c)
          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.

file	content
go_majors.json	Per-series majors: release date + key features (Go 1.0 → 1.27)
go_release.html	Official GOOS release-history page (patch dates/notes), as downloaded
python_majors.json	Per-series majors: date + key features (Python 3.0 → 3.15)
python_patches.json	Active patch releases (version → date) per series
python_finals.json	Final release of EOL series (3.0 → 3.8)
js_es.json	ECMAScript editions ES5 → ES2027 (date, status, features)
js_node_features.json	Feature highlights per Node.js major line (4 → 26)
js_node_legacy.json	Legacy Node.js 0.10.0 / 0.12.0 rows
node_index.json	Official nodejs.org dist index (all versions: date, V8, npm)
kotlin_majors.json	Per-series majors 1.0 → 2.4: date + key features
kotlin_legacy.json	Final patches of 1.0 / 1.1 / 1.2 (not in endoflife.date)
rust_majors.json	Rust 1.0.0 landmark row (date + key features)
rust_editions.json	Rust editions 2015 / 2018 / 2021 / 2024 (date + features)
licenses.json	Software license + license_url per project
statuses_go.json / statuses_python.json / statuses_node.json / statuses_kotlin.json / statuses_rust.json	Support/EOL phases per series (endoflife.date + python.org)

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.
