This hasn't been "reverted" in 4.x.x, as some have claimed. ArkoseLabs maintains multiple
<a href="https://git-scm.com/docs/git-branch" target="_blank" rel="noopener noreferrer">branches</a> and active deployments. The 4.x.x branch was created from an older revision that predates the 3.5.0 release. Both versions are being developed in parallel and will eventually be
<a href="https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests" target="_blank" rel="noopener noreferrer">merged</a>. Development has been very slow and could take a while to merge all the different active versions (2.x, 3.x, & 4.x).
</p>
<p>
In addition, ArkoseLabs performs
<a href="https://en.wikipedia.org/wiki/A/B_testing" target="_blank" rel="noopener noreferrer">A/B testing</a> on new versions with a limited user base before broader rollout. Clients will eventually have to migrate to the
<a href="https://developer.arkoselabs.com/docs/pick-a-tile-end-of-life-communication" target="_blank" rel="noopener noreferrer">new versions</a>.
