Note that many artifacts have the -alpha suffix attached to their version number, reflecting that they are still alpha quality and will continue to have breaking changes. Please see the VERSIONING.md for more details.

⚠️ Breaking Changes

• Remove support for previously deprecated property otel.instrumentation.logback-appender.experimental.capture-logstash-attributes (#15722)
• Remove deprecated methods from HTTP library instrumentations (#15802)

🚫 Deprecations

• JMX Metrics: Deprecated addClassPathRules and addCustomRules methods in JmxTelemetryBuilder, and moved non-public classes to an internal package (#15658)
• Deprecated setMessagingReceiveInstrumentationEnabled in favor of setMessagingReceiveTelemetryEnabled to match config property name (#15668)
• Deprecated database client attribute getter methods getDbSystem() and getResponseStatus() in favor of getDbSystemName() and getResponseStatusCode() to align with stable semantic conventions (#15696)
• Deprecated setCapturedRequestParameters() in Servlet library instrumentation in favor of Experimental.setCapturedRequestParameters() as request parameter capture is experimental (#15826)
• Deprecated getHttpClient(), setHttpClientTransport(), and setSslContextFactory() in Jetty client instrumentation in favor of new builder-style methods newHttpClient(), newHttpClient(SslContextFactory), and newHttpClient(HttpClientTransport, SslContextFactory) (#15827)
• Deprecate Netty experimental method that is still in public API (#15828)
• Deprecated newHttpClient() in favor of wrap() in Java HTTP Client instrumentation for consistency with naming conventions across library instrumentations (#15829)
• Deprecated new* methods in favor of create* methods across multiple instrumentation libraries for consistency (e.g., newHttpClient() → createHttpClient(), newInterceptor() → createInterceptor()) (#15832)
• Deprecated methods in SqlStatementInfo and MultiQuery in favor of methods using stable semantic convention terminology: getFullStatement() → getQueryText(), getOperation() → getOperationName(), and getStatements() → getQueryTexts() (#15833)
• Deprecated database getter methods in favor of methods using stable semantic convention terminology: getResponseStatusCode() → getDbResponseStatusCode(), getBatchSize() → getDbOperationBatchSize(), and getQueryParameters() → getDbQueryParameters() (#15859)
