# Development Update for Week 10 (Mar 4 - Mar 10) Our [v2.2.0-prerelease](https://github.com/lexicongovernance/pluraltools-backend/releases/tag/v2.2.0-prerelease) went live last week in advance of the v2.2 release this week The largest visible change was to the user registration form: user name submission is now split into two fields for faster and cleaner population of the author field in the voting page and to facilitate sorting by surname ![image](https://canada1.discourse-cdn.com/flex029/uploads/arbitrum1/original/2X/6/656366f5ae9ba76e04a51ff349b30edb06174c54.png) ![image](https://canada1.discourse-cdn.com/flex029/uploads/arbitrum1/original/2X/8/8bb010098f191c88a3501b426e45e2d7d58d5587.png) Beyond that, the focus is on backend improvements to ensure a smooth experience, with updates including: - further improved routing to ensure users are directed to the correct subpage faster - added authorization logic to prevent user manipulation of results via the API (unlikely, given the invitee list and the high risk of detection, but still good practice) - preparations for fast import of new group dimensions, with immediate update of plurality scores - updates to email notification service As always, the latest release and ongoing work can be seen in our [github](https://github.com/lexicongovernance/) --- _[View the full topic](https://forum.arbitrum.foundation/t/pl-plural-mev-research-tooling-update/20596)._
