# May 2025

> May 2025 release notes for Suki APIs and SDKs

This release adds problem-based charting, audio buffering, multilingual support, and resolves offline upload and session recovery issues.

## What's new

**May 2025 - New**

### New features

Web SDK v2.0.2

**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).

iOS SDK v2.1.0

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

## What's enhanced

**May 2025 - Enhanced**

### Enhancements

Web SDK v2.0.1

**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.

iOS SDK v2.1.0

**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.

## What's fixed

**May 2025 - Fixed**

### Resolved issues

iOS SDK v2.1.0

**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.
