We're now hard at work on our next quarterly release, Centaur, which will be rolling out in the December 2025/January 2026 time frame.

Please follow this article and its comments to receive updates throughout the quarter about new features and functionality that we're working on for the Centaur release. We'll also use this document to capture highlights of additions and updates to our mobile platforms and the xMatters REST API.

For a list of changes made in each deployment that aren't covered in the Development Highlights, see the support notes included below each highlight. While most features will be added to production environments as part of our quarterly releases, the support notes typically describe fixes, which can sometimes affect product behavior.

Release schedule

Here are the dates we're expecting the release to be available:

• Non-production environment access: Tuesday, December 9, 2025

xMatters iOS app v5.18 and xMatters Android app 4.17

On Jan 5, we released the latest versions of our mobile apps on the App Store and Google Play Store. Here's what's new:

• To help mobile users understand their on-call schedule better,  the shift escalation screen now displays additional details.
• Bug fixes and performance improvements.

Feature Spotlight on Notifications report

The Notifications report gives you detailed visibility into your notification data, helping you review delivery and response timing and see how notifications are moving through your system. The 'Time to Deliver', 'Time to Respond', 'Time to First Response', and 'Created' columns make it simple to understand notification timelines at a glance. The report also includes 'Notifications by Device Type' and 'Notifications by Source' charts so you can visualize your data and see patterns across notifications.

Upcoming Code Freeze

Over the next couple of weeks we're pausing deployments and updates across xMatters to ensure a stable and reliable experience for customers during peak retail seasons. You can learn more about how we manage releases throughout the year, take a look at our support article, xMatters Deployment & Early Access. We look forward to supporting you in 2026! 

Feature Spotlight on holiday shifts

Holiday shifts in xMatters give on-call groups the ability to adjust their coverage on days defined as site holidays. These shifts are automatically scheduled for holiday dates and can be used to give members the day off, change working hours, or allow more time to respond to notifications. Holiday shifts are most useful for groups that are active only part of the time and are not typically configured for groups that are active around the clock, such as those using a single 24x7 shift for emergency messaging.

You can define holiday coverage in several ways. The simplest approach is to create a separate holiday shift, but you can also specify whether existing shifts should be on call or off call for all or part of a holiday. Before holiday options appear in the interface, your on-call group must select a site to use for holidays and that site must have holidays configured.

Centaur release overview

On Tuesday, December 9, the latest features from our Centaur release trotted into non-production instances! These updates include enhanced subscriptions management, new Gemini AI integrations, restricted public status pages, Google Meet and Zoom Flow Designer steps—and lots more. If you're wondering what else is new, our Centaur Release Overview is your complete guide to everything that's included.

Feature Spotlight on site holidays

Configuring the correct site holidays is an important part of effective on-call shift scheduling. The Holidays page in xMatters provides a single place to add, manage, and configure the holidays your sites use. Instead of working across separate company, site, and custom holiday pages, you easily can manage everything in one place.

Admins can choose holidays from a list of standard options or create custom holidays in the side panel with specific recurrence settings. Once holidays are set up, users can open the 'Edit Site' panel on the Sites page and select which holidays each site observes based on the country it is located in. This helps keep schedules accurate and ensures each site follows the correct holiday calendar.

REST API: Signals endpoint

The new Signals endpoint lets you use the xMatters REST API to pull information about all signals, or a specific signal in your instance. Everything you see in the Signals report is now available via REST API. You can embed incidents related to the signal, filter by response code, or set the request for a specific date range. The returned response includes information on the workflow, trigger, trigger outputs, and authenticated user.

Ask the Incident AI Agent “Who is on call?”

The Incident AI Agent can now answer “Who is on call?” for a group or service by pulling current shift members from xMatters schedules and returning the members on duty. This makes it easier to find the right resolvers without searching through schedules or notifying an entire shift, helping teams move faster—and to avoid contacting the wrong person.

Feature Spotlight on shift coverage gaps

If a notification is sent to an on-call group at a time when it doesn't have an active shift, urgent alerts may be missed. The on-call group calendar clearly highlights coverage gaps in the schedule so that admins can easily identify and cover empty time slots. On the group calendar view, select the 'Highlight Gaps' check box to identify gaps in the calendar with a 'Shift Gap' warning. You can then adjust the surrounding shifts to cover this gap or click the highlighted area to add a new shift that covers the missing time. A side panel on the right side of the screen helpfully lists all the coverage gaps for easier scanning.

Holiday Code Freeze

We’re currently in one of our annual code freezes, where we pause deployments and updates across xMatters to ensure a stable and reliable experience for customers during the busiest times of the year. This helps make sure nothing unexpected changes in peak retail seasons (such as American Thanksgiving and Christmas).

Even though releases are on hold, you can still explore recent updates in the xMatters REST API docs. If you want to learn more about how we manage releases throughout the year, take a look at our support article, xMatters Deployment & Early Access.

Feature Spotlight on collaboration channels 

Clear communication is essential during an incident, and collaboration channels make it easy for teams to connect through the tools they use every day. The Collaboration section of the Incident Console shows all the channels a response team is using to communicate about an incident (such as a conference bridge for stakeholders, a Slack channel where the development team is collaborating on mitigation options, or a Teams channel where customer support is reviewing the latest user input).

Playbooks can also include collaboration channels so they are automatically added when an incident is initiated in xMatters. This allows teams to join the right conversations immediately without setting anything up. If your organization uses a channel that is not listed in xMatters, you can link an existing chat room or call by adding its URL. For Slack and Microsoft Teams, you can choose to have xMatters post updates about the incident, including changes to status, severity, description, properties, impacted services, linked incidents, notes, or tasks, ensuring channels stay aligned with the latest information and helping teams remain informed throughout the incident.

Live call routing sub-group evaluation available in EAP

Live Call Routing has been enhanced to better identify available responders by evaluating sub-groups when connecting a caller. Previously, the system only looked at users and devices assigned to the top-level group. With this update, Live Call Routing now checks any sub-groups within that group and includes their members in the search. This improves the reliability of reaching someone who can help and allows teams to keep their existing schedules, rotations, and group hierarchies without needing to adjust them for call routing.

Restricted public status pages available in EAP

If you need to limit visibility to your public status pages, you can now restrict access so that only specific audiences can view the content. This allows you to control who sees sensitive information while still keeping key groups updated. Whether fully public or restricted to selected viewers, status pages provide a flexible and secure way to communicate with the people who need to stay informed, without requiring additional xMatters licenses.

ServiceNow Everbridge Flow Designer app v1.2.1

Version 1.2.1 of the ServiceNow Everbridge Flow Designer app is now live. This update includes:

• Corrected permissions so anyone with a role assigned to an Action is able to view it.
• Updated default filters for Logs and Events to display entries from the current day.

xMatters iOS app v5.17

The latest version of the xMatters mobile app is now in the App Store. Here's what's new:

• Further customize how your user schedule is displayed by filtering on-call shifts by groups.
• Intuitively navigate your calendar by swiping to go back and forth in the day and month views.
• Additional bug fixes and performance improvements.

Feature Spotlight on user schedule

When you’re on call, having a clear and customizable schedule is essential for managing your time effectively. The user schedule in xMatters has been designed to prioritize both functionality and usability, making it easy to see and manage your shifts at a glance.

You can also add the on-call widget to your dashboard, which shows how long you’re currently on call or when your next scheduled shift begins. This lets you see what you need at a glance without having to open your full schedule.

November 10 - 14, 2025

Feature Spotlight on scheduled messages

Coordinating notifications across teams and time zones can be challenging—especially when messages need to be sent outside of regular working hours. Scheduled messages allow you to schedule a form or scenario to send in the future, either as a one-time notification or on a recurring basis, so messages automatically reach recipients at the right time.

You can choose from several frequency options, including daily, weekly, weekdays, weekends, monthly, and yearly schedules. The 'Custom' option also allows more advanced configurations, such as sending messages every three days, on specific weekdays, or on the first Monday of selected months. Whether you’re sending reminders, status updates, or time-sensitive alerts, scheduled messaging ensures communication stays consistent across teams and schedules.

Feature Spotlight on end of escalation notifications

During a fast-paced incident response process, it’s critical to know when an alert has gone unanswered so the right people can take action. The end of escalation notifications feature allows you to automatically notify specific users or groups when no shift members respond to alerts before an escalation sequence ends.

If an escalation reaches the end of its sequence, an end of escalation notification can be sent to a user or group so they can better understand why it happened. The message includes important details about the alert—such as when it was initiated and the target group’s name and on-call shift—as well as a link to the Alerts report. This information helps supervisors assess any issues with scheduling and make adjustments to prevent similar situations in the future.

October 27 - 31, 2025

Feature Spotlight on incident attachments

When an incident occurs, providing additional information through documents and attachments can give teams the context they need to help them resolve issues more quickly. Incident attachments provide incident commanders the ability to seamlessly share key documents (such as process guides, screenshots, or best practices) directly within an incident. For resolvers or stakeholders who join later in the process, these attachments can offer crucial details to ensure they get up to speed fast.

The Document Library enhances this capability by allowing teams to easily upload and manage files within xMatters. Having key materials readily available makes it even faster to include the right information in messages and updates, keeping everyone aligned and focused during the critical moments of an incident

About the early access delivery process

Customers can choose to opt their non-production environments into an Early Access Program (EAP) to see new functionality before it's released. If you're considering signing up for the early access program, there are a couple of important things to know:

• Enrollment in EAP can be turned on any time through a support request.
• Exiting EAP can only be done on quarterly boundaries (you cannot opt in and out between quarterly releases).

For full details, refer to the official xMatters Deployment Process & Early Access article.
