What's New

On-Call Optimizer is continuously improving. Get the details on the latest changes and updates.

SOC2 Compliance

On-Call Optimizer’s SOC2 Type II report has been issued providing third party validation of our commitment to security & compliance and demonstrating how important it is to use to build, earn and retain our customer’s trust.

If you require a copy of our SCO2 report please request access to our trust center, or read the blog post for more details.

Configurable time/date format

A new user setting has been added to provide choice over how dates and times are presented. The setting can be found on your profile page (accessible by clicking the user icon in the top-right corner of the application, and selecting My Profile).

The available time formats are:

  • Friendly (default): Thu 05 Jun 2025 09:18
  • Concise: 2025-06-05 09:18
  • Concise with day: Thu 2025-06-05 09:18

Regardless of the format chosen, hovering on any time/date displayed in On-Call Optimizer will continue to show a detailed description of the time/date including the timezone.

Swap cancellation

Cancelled swap requests are now retained in On-Call Optimizer and can be viewed in their cancelled state - previously when cancelling a swap request it was immediately deleted leaving no trace in the application.

This means that clicking on a notification link for a swap that has since been cancelled no longer results in a page not found error!

Automatic cancellation

Swap requests where the shift being swapped is no longer assigned to the requesting member are now automatically cancelled. The requesting member will receive a notification when this occurs.

Calendar Improvements

  • Importing events from a calendar provider user account with a different email address from the email address of the On-Call Optimizer account is now supported (e.g. linking your personal user.personal@gmail.com calendar to your work On-Call Optimizer account - user@company.com).

    Events organized or accepted by either your On-Call Optimizer email or the email of the connected calendar account will be imported by On-Call Optimizer.

  • Calendars can now be configured to block or prefer all accepted events. For example, if you have a specific calendar containing only events you are unavailable for, you can configure On-Call Optimizer to create an availability block for each event imported from that calendar without needing to add individual “no-oncall” tags to each event.

    The new behaviour can be configured on a per-calendar basis instead of the existing behavior of importing only those events matching a specific tag, which remains the default choice for existing calendars.

    The calendar configuration screen has a new drop-down replacing the old toggle button to allow configuration of the new behaviour while also preserving the existing behaviour.

Bugfixes and minor changes

  • Fixed display of calendar cells with many events. If more than 5 rows of events need to be displayed in any cell, a link to display a popup window showing the remaining events will appear at the bottom of the cell.
  • Fixed time zone handling in the calendar to always use the configured time zone for the current user when grouping events into days.
  • The red/green color used for block/preference display on the member availability calendar has been improved to a less saturated value more in keeping with the rest of the calendar event colors.
  • The export synchronization process has been improved to prevent a difference being reported when the shifts being exports from On-Call Optimizer are already present in the external destination in a slightly different form (e.g. a 2-day shift on On-Call Optimizer would previously require an identical 2-day override in the external destination, but will now accept 2 1-day overrides if their start/end times and assignees otherwise match what On-Call Optimizer would export).
