Starting on September 30th, we began a progressive rollout to update the Split UI, bringing it closer to the look of Harness:
Beyond a change in color scheme, you will also see two changes to terminology:
Workspaces will now be known as Projects in the UI
Organizations will now be known as Accounts in the UI
Note: These terminology changes are being made only to labels in the UI at this time. To avoid introducing a breaking change, the Admin API will continue to use the strings ws, workspace, organizationId, and orgId until further notice.

Monitoring
Traffic Insights and Alerts
The Alerts tab has been renamed Monitoring and expanded to show real-time traffic insights over time and any alerts fired for the flag on a single page.
By default, traffic over the Last 48 hours is shown, but you may also select the Last 7 days, another Time range, or a specific Feature flag version:
Changes made to flags (i.e., new flag versions) are displayed as vertical bars for context:
When requesting a manual recalculation of metrics, you can reduce the computation time by limiting the recalculation to Key metrics. To select this faster path to results, click the Recalculate button and then click Key metrics only. If you prefer to recalculate Key, Supporting, and Guardrail metrics, click All metrics instead.
Reminder: Key, Supporting, and Guardrail metrics are automatically calculated on a schedule, starting five minutes after a feature flag change and going to progressively longer intervals until the last automated calculation at 28 days. You do not need to press the Recalculate button unless you want to kick off a calculation before the next scheduled run or after the 28-day mark.
We’re excited to announce the next step in improving metric categorization for your feature releases and experiments: Supporting metrics. This new metric category gives you greater control over metrics monitored per feature flag, helping you focus on what truly matters.
What’s changing?
On the Metrics impact page, we have replaced “Organizational metrics” with “Supporting metrics.” Now, you can easily select specific additional metrics to track for each release, reducing noise and making it easier to analyze your results.
How do I assign flag-specific metrics?
Key metrics and Supporting metrics are specific to individual feature flags, and can be managed on a flag’s Metrics impact tab. Under each category, click “Add metric” to initiate the process of assigning metrics to the category. Once metrics are added, you can wait until the next scheduled calculation or manually “Recalculate metrics” to see results.
How do I ensure my important metrics are still monitored for every flag?
In June, Split introduced Guardrail metrics to improve your ability to define which metrics should be monitored for every flag. Guardrail metrics include automated alerting, meaning flag owners will be notified as their releases or experiments impact these metrics.
Since Organizational metrics will no longer be available, we recommend adding important metrics to the new Guardrail metrics category ASAP to ensure they continue to be protected and limit any disruption of analyzing metric results. Guardrail metrics can be assigned in the metric definition:
The combination of Key metrics, Guardrail metrics, and Supporting metrics will reduce noise and increase sensitivity while ensuring important metrics are monitored for every feature release or experiment. We welcome your feedback as we continue to improve our metric results!

Monitoring
Guardrail Metric Alerts
Flag owners will now automatically receive alerts on any guardrail metric without manual configuration.
Alerts are sent to flag owners whenever a guardrail metric moves significantly in the desired or undesired direction. This feature is designed to help you make safe and accurate release decisions in a timely manner.
As a reminder, Guardrail Metrics (released 2024-06-14) ensure that an organization’s most crucial metrics are protected and monitored throughout every feature release and experiment by making their calculation automatic and mandatory for all flags that use the same traffic type as the metric.
Metrics are set as guardrail metrics for your workspace on the Metric definition page. View the docs here

Monitoring
Guardrail Metrics
Users can now categorize their organization’s most important metrics as “guardrails”. Guardrail metrics are those your organization wants to protect during a feature release or experiment. Metrics are set as guardrail metrics for your workspace on the Metric definition page.

SDK Enhancements
Semantic Versioning Targeting
Using the latest Split SDKs, users can more easily define targeting rules for new features based on app, OS, and other versions using attribute-based targeting. The SDK then automatically serves the appropriate treatment to users without needing additional code configurations. Split’s native Semantic Versioning Targeting removes the additional complexities and manual work that comes with targeting different application versions, allowing users to seamlessly deliver different experiences.

Usability Enhancements
Left Navigation Enhancements
Left-hand navigation within the application has been optimized. With this change, we’ve narrowed the navigation bar, migrated the search function to a modal dialog, and moved account settings to the bottom of the page. This makes frequently used actions (e.g. workspace switching) more readily accessible within the UI.
Release date:
2024-05-03
SDK Enhancements
Split Suite, iOS SDK
Users can automatically capture event data in Split using their iOS SDK without needing additional agents, integrations, or track calls. This eliminates the manual process of sending events to Split, allowing users to quickly set up metrics and alert policies.
Monitoring
Out-of-the-Box Metrics
Split automatically creates metrics for any events being auto-captured by the Split Suite and RUM Agents (Web, Android, iOS). This reduces the manual effort of creating metrics and allows users to easily calculate their engineering and performance metrics.
Release date:
2024-04-16
Usability Enhancements
Switch Updates
Users can now use Switch, Split’s in-app AI assistant, to easily summarize their experimentation results. Simply click on any metric card and hit the summarize button for a full analysis of your data. Please note, that this is a Generative AI feature that leverages end-user/customer data and will only be available to users who have specifically requested it to be enabled via Split’s Support team.

Usability Enhancements
Change Request Management
To help teams easily coordinate and collaborate on flag updates, we added shareable direct links to change requests. This allows teams to quickly share feature flag updates with key stakeholders and get faster approvals when needed.
Release date:
2024-02-09
Usability Enhancements
Switch Updates
Users can cancel a response from Switch mid-flight. This allows users to move forward quickly in cases where they asked the wrong question or if the response they needed was already on the screen.
Users can now also copy code snippets directly from Switch, enabling faster time to value.

2024-02-08
Usability Enhancements
Filtering Improvements
To help teams quickly find the information they are looking for, Split has improved the filtering experience in these lists: feature flags, segments, and metrics. Users’ most recent search filters will be preserved as users continue to navigate the product.
Feature Experimentation
Sequential Testing Update
Users can now reduce the minimum sample size to 100 at the organizational level via the admin setting. This allows users to get statistically significant results, faster.
Release date:
2024-01-16
Usability Enhancements
Toast Notification Update
Toast notifications will now appear in the lower right corner of Split’s UI. This increases the visibility of the notification and enables users to easily take additional action within Split.
Release date:
2024-01-09
SDK Enhancements
Split Suite, Android SDK
Users can now automatically capture event data in Split for their Android SDK without needing additional agents, integrations, or track calls. This eliminates the manual process of sending events to Split, allowing users to quickly set up metrics and alert policies.
