Customers in MinIO are allowed LTS on any release they choose to standardize. Production setups seldom change and require maintenance. Hotfix branches are such maintenance branches that allow customers to operate a production cluster without drastic changes to their deployment.

## Backporting a fix

Developer is advised to clone the MinIO source and checkout the MinIO release tag customer is currently on.

**NOTE**: When configuring multiple OpenID based authentication providers on a MinIO cluster, any number of Role Policy based providers may be configured, and at most one JWT Claim based provider may be configured.

<details><summary>Example 1: Two role policy providers</summary>

Sample environment variables:

// ClusterCIDR represents a single configuration for per-Node Pod CIDR
// allocations when the MultiCIDRRangeAllocator is enabled (see the config for
// kube-controller-manager).  A cluster may have any number of ClusterCIDR
// resources, all of which will be considered when allocating a CIDR for a
// Node.  A ClusterCIDR is eligible to be used for a given Node when the node

## Enabling Parquet Format

Parquet is DISABLED by default since hostile crafted input can easily crash the server.

If you are in a controlled environment where it is safe to assume no hostile content can be uploaded to your cluster you can safely enable Parquet.
To enable Parquet set the environment variable `MINIO_API_SELECT_PARQUET=on`.
