This introduces Application Insights Java SDK 2.4.0. This adds all the functionality introduced in 2.4.0-BETA and some additional bug fixes and enhancements.

Important Note: Spring Boot Starter Version

Previously, the Spring Boot Starter had an independent version number, causing some confusion. Future versions the Spring Boot Starter version will track with the SDK version. There will not be a Spring Boot Starter version 1.2.0, and in it's place version 2.4.0.

Changes introduced in 2.4.0-BETA

The changes to WebTelemetryModule in 2.4.0-BETA were reverted back the state in 2.3.1.

Enhancements

1. Added retries to CDSProfileFetcher #901
2. Added caching of sdk version id, reducing number of file IO operations #896

Bug Fixes

1. Fix #907 - Ensures string compare is case insensitive when running a SQL explain on a select statement.
2. Fixed ThreadLocal leak #887
3. Fixed QuickPulse schema version #904
4. Fix #919 - Fixed issue when adding duplicate Windows performance counter.
5. Misc stability improvements #932, #941, #945, #946, #947, #948

Welcome to Application Insights Java SDK 2.4.0-BETA and SpringBoot Starter 1.2.0-BETA. This version introduces several enhancement and bug fixes.

Removed and Deprecated

1. Removed support for multiple apps instrumented with single JVM Agent. Instrumentation will only work for single apps in application server.
2. Deprecated class ApplicationInsightsHttpResponseWrapper.java

Breaking change

1. WebRequestTelemetry interface now has another method setRequestTelemetryContext. This is needed to propagate context explicitly in asynchronous environments. This change is likely to break clients relying on implementation of this interface in their code.

Enhancements

1. Introduced beta support for manual context propagation in Async and Explicit Multithreading scenarios.
   Please refer to this wiki (https://github.com/Microsoft/ApplicationInsights-Java/wiki/Distributed-Tracing-in-Asynchronous-Java-Applications) for instructions.
2. #444 Introduced support to capture asynchronous request.
3. #749 Introduce beta supported instrumentation for Postgres SQL jdbc4 driver prepared statements via JVM Agent.
4. Introduced experimental API's AIHttpServletListener, HttpServerHandler, ApplicationInsightsServletExtractor and HttpExtractor.
5. Introduced WebTelemetryModule.setRequestTelemetryContext API.
6. #797 SDKLogger can now be enabled using system properties.

Bug Fixes

1. #879 Fixed issue with request/dependency correlation
2. Fixed #826 Remove duplicate Postgres provider.
3. #881 Fix SDK version in QuickPulse Telemetry.
4. #883 Fixed dependency metric collection for QuickPulse/LiveMetrics
5. #852 Fixed bug in PreparedStatementVisitor to instrument all overloads of setTimestamp.
6. Various stability improvements: #850 #849 #842 #847 #843 #887 #888

Welcome to Application Insights Java SDK 2.2.0 and Application Insights SpringBoot Starter 1.1.0-BETA! This release comes with brand new enterprise grade features and critical bug fixes to both SpringBoot Starter as well as Core SDK.

Enhancements and changes:

1. Introducing SpringBoot Starter 1.1.0-BETA.
2. Introducing LocalForwarderChannel(beta) for use with the LocalForwarder (https://github.com/Microsoft/ApplicationInsights-LocalForwarder)
3. Starter now respects autoconfiguration for Micrometer(https://micrometer.io) metrics.
4. Starter now supports reading iKey using all the variable names as core sdk.
5. Starter would no longer support relaxed binding of ikey property due to complex conditional need and backport problems with RelaxedBinder from Boot 2 to 1.5.x.
6. Added WebAppNameContextInitializer for use with the WebRequestTrackingFilter.
7. Introduced CloudInfoContextInitializer to set roleInstance in CloudContext. This new initializer is included by default and therefore will not affect the current tags.
8. Deprecated getRoleName/setRoleName and getRoleInstance/setRoleInstance in DeviceContext. Introduced CloudContext to hold replacements, getRole/setRole and getRoleInstance/setRoleInstance, respectively.
9. Removes Servlet 3.0 annotations from WebRequestTrackingFilter and ApplicationInsightsServletContextListener which were causing issues in certain cases. This will allow easier customization of the filter. To use the listener moving forward, it will need to be defined in web.xml.
10. Starter adds autoconfiguration for Local Forwarder Telemetry Channel. (Please look at readme for details on configuration.)
11. InterceptorRegistry class no longer has @EnableWebMvc annotation as it breaks springboot autoconfig.

Welcome to Application Insights Java SDK 2.1.1! With this version we announce ApplicationInsights-Spring-Boot-Starter-1.0.0-BETA. This starter is currently in BETA. In order to use SpringBoot starter please refer to https://github.com/Microsoft/ApplicationInsights-Java/blob/master/azure-application-insights-spring-boot-starter/README.md

Enhancement and API changes:

• Introducing support for SpringBoot via Application-Insights-SpringBoot-Starter #646. This is currently in beta.
• We have made some fields in core SDK public for supporting SpringBoot starter.
• Introduced public constructor in InProcessTelemetryChannel.java class.
• Introduced a public method getActiveWithoutInitializingConfig() in TelemetryConfiguration.java class.

Welcome to Application Insights Java SDK 2.1.0! We have added support for heartbeats and made performance optimizations in the SDK's initialization code. A couple of other issues have also been fixed. See details below:

Enhancements:

• Introduced a Heartbeat feature, which sends periodic messages with basic information about application and runtime to Application Insights.
• Performance improvements during initialization.

Bug Fixes:

• Fixed an issue whereby the SDK could not resolve instrumentation keys if a proxy was specified in the JVM (via http.proxyHost). The fix enables proper support for system properties in the instrumentation key resolver component.
• Fix #647 - If a performance counter cannot be computed, it will not report a placeholder value (-1). Instead, it does not report any value.

Welcome to Application Insights Java SDK 2.0.2! This release fixes a number of issues posted on GitHub by the community and ourselves. It also includes a few enhancements to diverse areas. Details below.

Note: This release requires that the SDK be run on an application server supporting Servlet 3.0 or above.

Enhancements:

• Enable real-time SDK Logs when logging to file - #616
• Log messages are now being pushed as custom dimensions when exceptions are reported via log appenders - #400
• Enhanced Log4j2 appender to support basic parameters including Filters, Layouts and includeException - #348
• Support for configuring channel retries (MaxInstantRetries) in ApplicationInsights.xml
• Added the ability to have cold SDK initialization (no logs except critical logAlways messages)
• Code cleanup in the session tracking feature - #577

Bug Fixes:

• Fix incorrect success flag set when capturing HTTP Dependency.
• Fixed issue with sessionId not being set in request telemetry due to date parsing incompatibilities.
• Fix #609, fixes the inaccurate timestamp recorded with JMX Metrics.
• Fix issue when dependency start time was not being recorded correctly.
• Fixed #533 HTTP Dependency Telemetry now matches with .NET SDK.
• Fixed PageView telemetry data not being reported.
• Fixed Issue #526 (NPE in MapUtil.copy()).
• Fixed Issue #513 (Memory leak in SDKShutdownActivity). This fix upgrades our Servlet version from 2.5 to 3.0. The SDK must now be run on an application server supporting Servlet 3.0.
• Fixed Issue #504 (SDK initialization happens twice) to improve startup performance.

API changes (back-compatible):

• Introduced public method httpMethodFinishedWithPath(String identifier, String method, String path, String correlationId, String uri, String target, int result, long delta)
  to support instrumentation of Path of URI in HTTP requests.
