v1.270.0
Features
Remove supportsSendBeacon runtime property
Removes the supportsSendBeacon runtime property from our agent code. We no longer officially support browsers that cannot use the sendBeacon method, so there's no point in checking for it.
Add Firefox to LCP test matcher
Add Firefox versions 122 and above to LCP test matcher since versions 122 and above now support collection of LCP web vital timings.
Remove 'pageHide' from page end-of-lifecycle listener
Remove pageHide from page end-of-lifecycle listener since browser agent support for Safari 14.4 is deprecated
Move deregisterDrain method to feature-base
Moves the deregisterDrain method in order to standardize the implementation pattern to match the drain method.
Relocate aggregator from loader and improve agent internals
Styling and architectural changes that will reduce agent loader size by moving the Aggregator module to async chunk and removing the need for some configuration getters in the features. No behavioral change or significant performance impact from the agent is expected.

v1.269.0
Features
Include logging feature in micro agent loader
Allow the MicroAgent loader on NPM to utilize the logging APIs to manually capture log data.
Add instrumentation metadata to logging
Add instrumentation attribution to logging payloads to fortify categorization and billing calculations in New Relic platforms. These attributes are dropped during processing and before storing the data and as such don't affect customer billing rates.
Bug fixes
Only ever allow session traces to capture page load timings once
An edge case issue was resolved where session traces could include duplicate copies of the page load timings obtained from the browser timing APIs.
Handle Session Replay Security Policy Errors
Handle Security Policy Errors encountered by session replay when browser APIs have been natively disabled. This was also observed to happen in Chromium browsers that completely disabled cookie storage. Supportability metrics about agent internal errors are now captured as a biproduct of this work to help facilitate future improvements.

v1.268.0
Features
Aggregate UserActions
Utilize sequential aggregation techniques when observing UserAction data to reduce ingest cost for customers.
Add UserAction to GenericEvents
Select user interactive events will be captured in this release. This is an extension of the GenericEvents feature meant to drive UI experience.
Bug fixes
Always return a string for custom stringify method
An internal mechanism used to convert JS values to string was returning undefined for certain values, which may lead to errors for downstream callers when they are expecting a string. This is part 2 of a patch to ensure a string is returned.
Force generic events feature to clear buffer when unloading
Fixed an issue where the generic events buffer was not clearing when unloading. This affected a small portion of experiences where the agent was "unloading" due to the page losing focus, but not actually closing. Subsequent harvests when the page was re-focused would have the potential for duplicated data.

v1.267.0
Features
Upgrade to web-vitals v4
Upgrade to web-vitals v4. For more info, please see https://github.com/GoogleChrome/web-vitals/blob/main/docs/upgrading-to-v4.md.
Improve notifications of stylesheet status for session replay
The agent reports internal metadata about the status of stylesheets on the page when collecting session replay information. This process was spotty and the logic has been improved to make the metadata more consistent. The ability to turn off "inlining" the stylesheets has been removed, as that behavior is required for the UI to re-render the replay.
Add soft navigations to Browser-Agent loader
Add the Soft Navigations limited preview feature to the default Browser Agent loader accessible via NPM.
Update TimeKeeper Source of Truth
Update the Agent's TimeKeeper to evaluate a timestamp provided directly by the consumer instead of a generic Date header, which should provide more control stability and granularity to the time synchronization processes.
Bug fixes
Improve reliability of customMasker
The customMasker method of the Session Replay feature has been fixed to be more reliable with DOM elements that do not fit web-standards, as to not throw errors when processing. Initial Replay harvests will now be gated until a valid snapshot is taken.
Stringify now returns an empty string if failed to transform
An internal mechanism used to convert objects to strings would return undefined if an exception was thrown during the process. This could lead downstream users of that method to throw errors if they expected the output to be a string. The utility method now always returns a string.
