When the Umetrix Data Mobile Client for iOS app restarts, it will use the testset and project that were used before the restart.

Long project and test set names are displayed fully; Provide a way to close the video in a Mobile Gaming test.

* Support for the Mobile Gaming task * A new and easy-to-use user interface

• One-way latency metrics for UDP Download and UDP Upload tasks are now supported. • Battery temperature is now displayed in the Umetrix Data for iOS app and in the RTTM data. • High throughput benchmark tests were conducted for different task types in the Spirent lab and on the Verizon UW network. Results are available upon request.

This release introduces the One Time Password (OTP) code for the Enhanced Client Security feature. When the Enhanced Client Security feature is enabled, Umetrix Data Server verifies whether the email address you specify when logging in exists in the User Directory and that the account status is “Active.” If you entered a valid email address that is active, Umetrix Data Server will send an OTP code to the email address associated with the login you entered. You must access this email message and enter the OTP code in the One Time Password dialog box provided by the Umetrix Data app. Umetrix Data Server will reject the login if any of the following conditions occur: • You enter an invalid email address. • The account associated with the email address is not active. • You enter an incorrect OTP code. This enhancement is optional. You must contact Spirent Support to activate Enhanced Client Security for your activation code.

This release contains the following enhancements: • The new task type BANDWIDTH SIMULTANEOUS HTTP is supported. BANDWIDTH SIMULTANEOUS HTTP initiates a multi-stream uplink test and a multi-stream downlink test simultaneously. You can add this new task type to test sets using the test set creator. • User configurable timeout values for TCP read timeout and TCP write timeout are supported. • Bug fixes

The following new task types are supported: -BANDWIDTH DOWNLINK HTTPS -BANDWIDTH UPLINK HTTPS -BANDWIDTH SIMULTANEOUS UDP -HTTPS DOWNLOAD -HTTPS UPLOAD iOS Dark mode is now fully supported For the full release notes, please visit https://support.spirent.com/SpirentCSC/SC_KnowledgeView?id=DOC11245

– Adds support for the new Bandwidth UDP task types. – Default support for the static number of streams option for the Bandwidth Uplink HTTP task. – Support for iOS Accessibility text settings.

• Dynamic Application Buffers – TCP and UDP task application buffers are dynamically allocated to take advantage of iOS’ optimized memory allocation code. Additionally, the task application buffer size has been increased to 1MB. • UDP Socket Receive Buffers – UDP task socket receive buffers have been increased to 2MB.

-All tasks now produce ONE_SECOND_BIN log messages which contain once-per-second snapshots of a task’s measured KPI e.g. throughput or round-trip time.

•iOS 11+ Support – Datum iOS now explicitly targets and supports iOS 11+ •Throughput Measurements – The UI now dynamically displays the current throughput measurement for a given task as Kbit/s, Mbit/s, or Gbit/s. The task result value remains Kbit/s in the Datum log file. •Configuration ID/IMEI – The configuration ID/IMEI field now supports non-alphanumeric characters to support strings such as an email address. oThe backslash ( \ ) or single-quote ( ‘ ) characters are still restricted and are not allowed. •Bandwidth Uplink Task Stream Count– The Bandwidth Uplink task now supports dynamically scaling up to 32-concurrent test streams. •History Tab – The number of task results displayed in app have been increased from the last 20 cycles to the last 100 cycles, and the task measured value will always be displayed, regardless of if the task passed, failed, or aborted. •Automatic Re-activation Toggle – Users can now optionally disable or enable automatic re-activation. •Show Password Button– Users can now view their activation code (iOS “password”) by tapping on the Eye icon next to the entry field. •Radio Preference – An alert is presented to a user now if their current radio access technology does not match the selected radio preference. Selectable preferences include: oAny oCellular oWi-Fi

-UI update for iOS 10+ devices -NTP synchronization operations will now timeout after 500 milliseconds -FTP tasks now accept either 227 or 229 as a valid response for requesting FTP passive mode -Resolved a crash when tapping on the text tag entry field in the "Tags" view.

v2.8.0 - Datum iOS now supports the Datum Bandwidth Task for testing the maximum available uplink or downlink network throughput. This task uses a multi-stream approach to measure the bandwidth of a given network connection. v2.8.1 - Squishes some bugs

Datum iOS now supports the Datum Bandwidth Task for testing the maximum available uplink or downlink network throughput. This task uses a multi-stream approach to measure the bandwidth of a given network connection.

-Simultaneous UDP is now a supported task type. -For iOS 8 and up, the Web Task uses the WKWebView control instead of the legacy UIWebView control. -Diagnostics data now reports the Wi-Fi SSID and BSSID, and supports new columns for the data bearer and the telephony bearer. -At the end of a test cycle, a time-synchronization is performed against an NTP server to align the diagnostics data timestamps. -Squished several bugs.

2.7.1 -Addresses a UI issue where Datum would crash if the app was placed in the background for multiple testing cycles and then brought back to the foreground while testing result logs were being uploaded 2.7.0 -Built for iOS 8.0 -Continuous RTTM logging -Squishes Several Bugs

2.7.0 -Built for iOS 8.0 -Continuous RTTM logging -Squishes Several Bugs

-IP Analytics Support -Bug Fixes

-iOS 7 support -bug fixes
