Improvements​

• Guides & Surveys integrations now load (if enabled), including in child frames and on pages where session capture doesn't start.

Bug fixes​

• Fixed an issue where session restarts didn't re-trigger initial page-load signals (like page size reporting), which could result in incomplete data for restarted sessions.

New features​

• Under the hood changes to get ready for Snippet 2.1 release.

Improvements​

• Some optimizations for build size.

Bug fixes​

• Small code fixes related to Typescript update.

Improvements​

• Updated internal type definitions to ensure compatibility with newer versions of TypeScript.
• Optimized internal data structures (enumerations) for more efficient recording processes.

Improvements​

• Reduced bundle size by approximately 2% (gzip) by ensuring debug-only log messages are fully excluded from production builds.
• Minor performance improvement in DOM capture by reducing unnecessary function call overhead in the node encoding hot path.

Improvements​

• Return a user snapshot from FS('getConfig').
• Expose user properties set from fs.js via config details.

Bug fixes​

• Replace circular reference in vars with a path marker instead of dropping the value.
• Add a fallback to write snippet globals back to window when they're missing.

New features​

• Native HTML Popover Support: Added capture capabilities for the native HTML popover API to accurately record capture-phase toggle events and popover states for high-fidelity session replay.

Improvements​

• Enhanced Custom Namespace Resolution: Hardened how custom Fullstory namespaces are resolved across your site by reading the data-fs-namespace attribute for asynchronous integration scripts and data layers.
• More Predictable In-Session Configuration: Streamlined how in-session settings are initialized, prioritizing FS('getConfig') over raw window globals for a more robust recording configuration.

Improvements​

• Improved compatibility for Canvas screenshot mode.
• Added client-side guardrails and remediations to ensure Session UID stability and reliability.

Bug fixes​

• Minor internal maintenance and cleanup of unused script sidecar files.

Improvements​

• Added client-side guardrails that improve the stability and reliability of the Session UID feature.

Improvements​

• Improved observer configuration handling so that misconfigurations are gracefully rejected instead of throwing hard exceptions.

Bug fixes​

• Removed a duplicate license comment that appeared in the bundled fs.js output.

Improvements​

• Introduced throttling for realtime recording network requests to reduce load on backend services.

Bug fixes​

• Improved session lifecycle controls for Session UIDs and fixed an issue with userId preservation during non-stateless startup.

Bug fixes​

• Improved the reliability of capturing adoptedStyleSheets when a stylesheet is modified without explicitly reassigning it.

New features​

• Added support for capturing document-level mouseenter/mouseleave events to more accurately detect when a visitor's cursor enters or exits the browser viewport.
• Expanded CSS capture to record adoptedStyleSheets.splice() calls, so stylesheets modified this way are faithfully replayed.

Improvements​

• Reduced initial load overhead by delaying creation of internal capture data structures until they're needed.

Bug fixes​

• Fixed an issue in the console log scrubber's pattern matching that could cause some sensitive console output to not be masked.
• Refined Interaction to Next Paint (INP) analytics to properly ignore interactions on elements excluded from capture.

New features​

• Added native support for the Session UID API via the FS('init') configuration.
• Added capture hooks for adoptedStyleSheets.push(), so dynamically added stylesheets are captured for replay.
