-#
-# This constraints file was automatically generated on 2023-07-07T14:44:02Z
-# via "eager-upgrade" mechanism of PIP. For the "v2-6-test" branch of Airflow.
-# This variant of constraints install uses the HEAD of the branch version for 'apache-airflow' but installs
-# the providers from PIP-released packages at the moment of the constraint generation.
-#
-# Those constraints are actually those that regular users use to install released version of Airflow.
-# We also use those constraints after "apache-airflow" is released and the constraints are tagged with
-# "constraints-X.Y.Z" tag to build the production image for that version.
-#
-#
-# This constraints file is meant to be used only in the "apache-airflow" installation command and not
-# in all subsequent pip commands. By using a constraints.txt file, we ensure that solely the Airflow
-# installation step is reproducible. Subsequent pip commands may install packages that would have
-# been incompatible with the constraints used in Airflow reproducible installation step. Finally, pip
-# commands that might change the installed version of apache-airflow should include "apache-airflow==X.Y.Z"
-# in the list of install targets to prevent Airflow accidental upgrade or downgrade.
-#
-# Typical installation process of airflow for Python 3.8 is (with random selection of extras and custom
-# dependencies added), usually consists of two steps:
-#
-# 1. Reproducible installation of airflow with selected providers (note constraints are used):
-#
-# pip install "apache-airflow[celery,cncf.kubernetes,google,amazon,snowflake]==X.Y.Z" \
-#     --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-X.Y.Z/constraints-3.8.txt"
-#
-# 2. Installing own dependencies that are potentially not matching the constraints (note constraints are not
-#    used, and apache-airflow==X.Y.Z is used to make sure there is no accidental airflow upgrade/downgrade.
-#
-# pip install "apache-airflow==X.Y.Z" "snowflake-connector-python[pandas]==2.9.0"
