auroraxo opened a new issue, #73769:
URL: https://github.com/apache/airflow/issues/73769
## Finding
The README quickstart on `main` pins the quickstart install to
`apache-airflow==3.3.0`, but the newest published release is **3.3.2**
(2026-09-17) and `main`'s `pyproject.toml` declares **3.4.0**. The quickstart
therefore installs a two-releases-old version while presenting itself as the
default path.
**Location:** `README.md` line 177 (and the repeated pin in the extras
example below it):
```bash
pip install 'apache-airflow==3.3.0' \
--constraint
"https://raw.githubusercontent.com/apache/airflow/constraints-3.3.0/constraints-3.10.txt";
```
## Suggested fix
Update the quickstart pin and the matching constraint URL to the current
release (3.3.2), or reference a generic installation path (e.g. `pip install
apache-airflow` with a link to the constraints docs), so the quickstart cannot
drift from the release train again.
## Reproduction
Verified with [docrot](https://github.com/auroraxo/docrot)'s version-drift
scanner (`version_drift.py`), which reads the declared version from
`pyproject.toml` and flags release pins in READMEs that match neither the
declared version nor the latest published release:
```
apache/airflow declared 3.4.0 (pyproject.toml) latest 3.3.2 -> 1 stale pin
README.md:177 [pip-pin] 3.3.0
```
Full corpus scan (40 popular OSS repositories): `drift-results-v2.json` in
the docrot repository.
