# Changelog May 27, 2022

## Public Roadmap

This week we launched a [public roadmap](https://feedback.clerk.com). It contains a rough estimate of when we expect to start and release new projects. Although it's not guaranteed, it's a good glimpse into how we expect the weeks, months, and quarters ahead to unfold.

## Resilience upgrades

Out with the old, in with the new! We were nearing capacity for some of our infrastructure and needed to upgrade.

The upgrades successfully deployed with zero downtime!

## Bot detection upgrades

Over the weekend, we detected an unusual spike in bot activity associated with SMS verifications. We worked with Twilio to determine that this attack was ["toll fraud"](https://www.twilio.com/docs/verify/preventing-toll-fraud) - where attackers are able to steal money by receiving SMS messages.

We've upgraded our systems to detect and put a stop to the suspicious behavior. Though this attack did not manifest in downtime or security issues, the impacted customers were notified and will not be charged for SMS overruns.
