v1.253.0
Features
Soft Navigations trial
Introducing a lighter and simplified version of the existing spa feature that tracks soft navigations. This new feature still sends BrowserInteraction events, but the duration and finishing of those interactions have been redefined. As a replacement, it ought to reduce complexity and integration issues around the existing spa and exhibit better and faster performance.
Apply deny list to ajax metrics
The ajax deny list has historically only applied to the collection of ajax events and not ajax metrics. With this feature, the deny list will also be applied to the collection and reporting of ajax timeslice metric data. If an ajax request matches an entry in the deny list, both events and metrics will be blocked from being collected in the agent. This feature will be behind a feature flag to assess impact before final complete rollout. Thanks to community member @Wrhector for contributing this feature.
Preload the session replay recorder when properly configured
Load the session replay recorder module before the page load when configured to do so. This will increase visibility for recordable data for customers who have opted in to the behavior.
Isolate observation context per agent
Initial implementation of an isolated observation context per agent running on the same page. This reduces the modification of instances of globals like events and instead each agent will track its own observation context internally.

v1.252.1
Bug fixes
Fix webpack imports in npm package
Fixing some import overrides in our NPM package build to prevent imports existing that include code reliant on webpack globals. This will resolve the error Uncaught ReferenceError: __webpack_require__ is not defined when using the NPM package in a project that does not use webpack.
Page load after session timeouts don't start new session
When a session expires or becomes inactive while the user does not have the page open and they re-open the page, that is now treated as a new session.

v1.252.0
Features
Add types mappings for esm distribution
Adding typescript types mappings for the ESM distribution in the npm package.
Report config changes away from default state for UX improvement
Detect if the default config values have been altered at runtime. This is useful to evaluate what the reasonable defaults are across a customer base over time to provide a better UX.
Create more granular metrics about stylesheet fix success
Utilize a finer granularity when collecting success metrics on local stylesheet fixes for Session Replay compatibility.
Align browser reported uncaught syntax errors
Aligning the data reported for uncaught syntax errors across modern browsers. Chrome specifically fails to include the file name and line number in instances of SyntaxError. This could also cause issue in the New Relic error inbox where Chrome syntax errors were not being properly grouped.
Capture Internal Metrics for Session Replay Configurations
Capture supportability metrics sounding Session Replay configuration usage to improve user experiences around configuration of the agent's Session Replay feature.
Bug fixes
Add safe logic to snapshots
Safe-guarded a race condition where an asynchronous call to fix a stylesheet could trigger the agent to try to force a snapshot after it has already stopped recording due to a visibility change.
Fix adblock memory leak
Fixed memory leaks caused by request resolve failure (e.G. due to adblocker). Thanks to community member @Joe-Degler for contributing this fix.

v1.249.0
Features

Bug fixes
loader missing sub-resource integrity hashes
Sub-resource integrity hashes were not being properly generated and included in the loader for async chunks related to session replay. This would cause a warning to appear in the browser console, but would not block those chunks from loading. This would have only affected customers taking part in the session replay limited preview.
Fix API warning messages
Fix warning messages given by API calls made before the agent has initialized.
Traceids not random when using webcrypto
Fix non-random hexadecimal generation when using the webcrypto api, which in turn creates non-random traceIds, that always end in 00.
