# [2023-05-16] Improvements to Scheduler and changes to message link tracking

Source: https://developer.nylas.com/docs/new/release-notes/2023-05-16-link-tracking-changes/

## Improvements to Scheduler

We've made improvements to the Nylas Scheduler to help you book meetings more efficiently.

- The Scheduler now allows organizers to use a template when creating an event title. Organizers can now use variables such as the duration, invitee name, and email into an event's title. See the [Schedule editor documentation](/docs/v2/scheduler/creating-and-scheduling/schedule-editor/#event-template-title) for more details.
- You can now set the Scheduler's locale using a query parameter.
- Fixed a bug that prevented the locale drop-down menu from appearing correctly on scheduling pages.

## Changes to link tracking

Nylas has removed link-tracking links older than 90 days to mitigate a security vulnerability.

Message tracking links created before 2023-04-18 no longer redirect to the original site, and instead produce a 404 error. This update applies to both the US and EU data centers.
