Features Added

This stable release includes all features, breaking changes, and bug fixes from the 13.0.0-beta.1 and 13.0.0-beta.2 releases. Refer to the sections below for full details.

For a detailed guide on migrating from v12 to v13, see the Migration Guide.

Content Understanding 1.1.0 Changelog

Features Added

  • Billing and token consumption details are now available after analysis operations complete. Access via poller.operationState?.usage.
  • The operation ID is now available on the operation state via poller.operationState?.operationId.

Content Understanding 1.2.0-beta.1 Changelog

Features Added

  • Added toLlmInput helper that converts AnalysisResult into LLM-friendly text with YAML front matter and markdown content. Supports documents, audio/video, and classification hierarchies.

Core - Client - AMQP 4.4.2 Changelog

Bugs Fixed

  • Handle AggregateError in translate() for Node.js 20+ Happy Eyeballs (RFC 8305). When DNS resolution fails over dual-stack connections, Node.js now throws an AggregateError bundling IPv4 and IPv6 errors. The translate() function now translates all inner errors and returns a properly annotated AggregateError with correct retryable semantics. #38233
  • Clamp negative timeout values passed to setTimeout to a minimum of 0 when timeout budgets are exceeded in shared request/locking paths, preventing TimeoutNegativeWarning on Node.js v24+ (for example, during CBS authentication). #38166

Cosmos DB 4.9.3 Changelog

Bugs Fixed

  • #38124 Fixed incorrect SQL filter generation in ORDER BY queries with continuation tokens. Backslashes and single quotes in orderByItem values are now properly escaped in formatValueForSQL before being embedded in WHERE clauses.

Event Hubs 6.0.4 Changelog

Bugs Fixed

  • Fixed TimeoutNegativeWarning on Node.js v24+ when timeout budget is exceeded during CBS authentication by clamping remaining-time computations to a minimum of 0. #38166

Key Vault - Secrets 4.11.2 Changelog

Bugs Fixed

  • Fixed an issue where contentType passed to setSecret() and updateSecretProperties() was not forwarded to the service request body. #38301

Notification Hubs 2.1.0 Changelog

Features Added

  • Re-export RestError and isRestError from @azure/core-rest-pipeline for convenience.

OpenTelemetry Exporter 1.0.0-beta.40 Changelog

Bugs Fixed

  • When multiple Retry-After headers are received, the exporter now compares absolute deadlines to ensure envelopes are sent at the latest required time.

Features Added

  • Persisted telemetry files from previous sessions are now sent immediately on startup instead of waiting for the first successful export plus a 60-second retry interval.
  • All persisted files are now processed at startup, not just one file per retry cycle.
  • Outdated persisted telemetry is cleaned from disk before sending on startup.
  • The exporter now respects the Retry-After header from the backend when scheduling retries for retriable responses.
  • Throttled telemetry (429 responses) is now persisted to disk for retry instead of being silently dropped.
  • Specific GenAI properties are now truncated to 256KB instead of being exempt from truncation limits.
  • The exporter now reads the MICROSOFT_OPENTELEMETRY_VERSION environment variable and includes it in the ai.internal.sdkVersion tag with the mot prefix.

Breaking Changes

  • The AZURE_MONITOR_DISABLE_CUSTOM_DIMENSIONS_LIMIT environment variable is no longer supported. All custom dimension values are truncated to 8KB by default.

OpenTelemetry Instrumentation 1.0.0 Changelog

Features Added

  • First stable release of the Azure SDK OpenTelemetry Instrumentation library.

Playwright 1.1.5 Changelog

Bugs Fixed

  • Fixed failure during report upload for test runs longer than 5 minutes when using GitHub OIDC authentication.

Voice Live 1.0.0-beta.4 Changelog

Bugs Fixed

  • Fixed voiceSerializer to properly convert Azure voice properties (e.g., endpointId, customLexiconUrl) to snake_case wire format (endpoint_id, custom_lexicon_url). Previously, Azure voice objects passed through requestSessionSerializer were sent with camelCase keys, which the service rejected.

Features Added

  • Added distributed tracing support via @azure/core-tracing. Spans are emitted for the session lifecycle (connect, send, recv, close) following GenAI Semantic Conventions. Tracing is no-op by default and activates only when an OpenTelemetry tracer provider is registered — CommonJS apps can use the standard @azure/opentelemetry-instrumentation-azure-sdk bridge, while ESM and browser apps register an Instrumenter directly via useInstrumenter. See the Telemetry / Distributed Tracing section in the README, plus the new samples/telemetry/ (Node.js ESM, console + Azure Monitor) and samples/telemetry-browser/ (browser, Vite) samples.

unknown 1.0.0-beta.1 Changelog

Features Added

  • Added entraTokenProvider function for acquiring Entra ID tokens as PostgreSQL passwords.
  • Added configureEntraAuthentication function for automatic Sequelize Entra ID authentication via beforeConnect hook.
  • Support for pg (node-postgres) and Sequelize clients as optional peer dependencies.
