### 3.1 Automatic removal of non current objects versions

A non-current object version is a version which is not the latest for a given object. It is possible to set up an automatic removal of non-current versions when a version becomes older than a given number of days.

e.g., To scan objects stored under `user-uploads/` prefix and remove versions older than one year.

## Reporting a Vulnerability

If you think you found a vulnerability, and even if you are not sure about it, please report it right away by sending an email to: ******@****.***. Please try to be as explicit as possible, describing all the steps and example code to reproduce the security issue.

I (the author, [@tiangolo](https://x.com/tiangolo)) will review it thoroughly and get back to you.

## Public Discussions

You could **deploy a server** yourself using a combination of tools, you could use a **cloud service** that does part of the work for you, or other possible options.

For example, we, the team behind FastAPI, built [**FastAPI Cloud**](https://fastapicloud.com), to make deploying FastAPI apps to the cloud as streamlined as possible, with the same developer experience of working with FastAPI.

 * <p>To use this class the concrete subclass must implement the {@link
 * IteratorTester#newTargetIterator()} method. This is because it's impossible to test an Iterator
 * without changing its state, so the tester needs a steady supply of fresh Iterators.

    val repoDir = localRepository // Prevent capturing the Gradle script instance for configuration cache compatibility
    // This should be unified with publish-public-libraries if possible
    doLast {
        repoDir.get().asFileTree.matching { include("**/maven-metadata.xml") }.forEach {

There are some extra features to handle security apart from the ones covered in the [Tutorial - User Guide: Security](../../tutorial/security/index.md).

/// tip

The next sections are **not necessarily "advanced"**.

And it's possible that for your use case, the solution is in one of them.
