Airflow v2 - be carefull with 2026 airflow providers

[raphaelauv]

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

apache-airflow-providers-apache-spark==6.3.1

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

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
