GitHub user raphaelauv created a discussion: Airflow v2 - be carefull with 2026
airflow providers
Little public warning , since the release of pandas v3
multiple apache airflow providers compatible with airflow 2.11 can install
pandas in version 3+
example
```requirements.txt
apache-airflow-providers-apache-spark==6.3.1
```
```shell
export AIRFLOW_VERSION=2.11.2
export PYTHON_VERSION=3.12
uv pip install apache-airflow[otel]==${AIRFLOW_VERSION} --constraint
"https://raw.githubusercontent.com/apache/airflow/constraints-${AIRFLOW_VERSION}/constraints-${PYTHON_VERSION}.txt";
uv pip install apache-airflow[otel]==${AIRFLOW_VERSION} -r
airflow-custom-packages.txt```
```
so better to add fixed version like
```requirements.txt
apache-airflow-providers-apache-spark==6.3.1
pandas==2.3.3
numpy==1.26.4
```
In all case airflow v2 active support ended the 22 Oct 2025, so you must
switch to v3
