## What's new

<Update label="May 2025 - New" description="Problem-based charting and audio buffering" tags={["New Features"]}>
  ### New features

  <Badge icon="cube" size="sm" color="green">Web SDK v2.0.2</Badge>

  **Problem-based charting**: We've added support for problem-based charting (PBN) with LOINC via the `isPBNSection` property in `ambientOptions`.

  Learn more in the [Ambient guide](/web-sdk/guides/ambient-problem-based-charting).

  <Badge icon="mobile" size="sm" color="purple">iOS SDK v2.1.0</Badge>

  **Audio buffering and multilingual**: We've implemented audio buffering to reduce offline sessions caused by brief internet interruptions and added `SukiAmbientConstant.kMultilingual` for multilingual processing support.

  **Why it matters**: PBN supports problem-oriented documentation. Audio buffering reduces lost sessions from brief network drops. Multilingual supports diverse patient populations.

<Update label="May 2025 - Enhanced" description="Default UI and background recording" tags={["Enhancements"]}>
  ### Enhancements

  <Badge icon="cube" size="sm" color="green">Web SDK v2.0.1</Badge>

  **Default UI options**: We've updated default values for `uiOptions` to match the latest UI configuration: close button, start ambient button, dictation, copy, and insert script are enabled by default; create empty note is disabled by default.

  <Badge icon="mobile" size="sm" color="purple">iOS SDK v2.1.0</Badge>

  **Background recording handling**: We've added proper error handling when attempting to start recording while the app is backgrounded, providing clearer error messages and preventing unexpected behavior.

  **Why it matters**: Default UI aligns with recommended configuration. Background recording errors are clearer and easier to handle.
</Update>

## What's fixed

<span id="offline-upload-and-session-recovery" />

<Update label="May 2025 - Fixed" description="Offline upload and session recovery" tags={["Resolved Issues"]}>
  ### Resolved issues

  <Badge icon="mobile" size="sm" color="purple">iOS SDK v2.1.0</Badge>

  **Offline upload and session recovery**: We've fixed the "No record exist for offline upload" failure category identified through the note failure tracing dashboard. We've also improved session recovery reliability during network transitions.

  **Why it matters**: Reduces offline upload failures and improves reliability when the network drops and recovers.
