v1.0.0

• Initial 1.0.0 GA release
• jfr-mappers module no longer depends on telemetry-java-http11.
• Fix for a potential freeze when the number of events in a
  single JFR recording file exceeds the maximum queue size.
• Clean up temp dirs to prevent resource leak.
• Use camel case for event/metric names instead of inconsistent delimiter.
• Clear per-thread cache data between harvest cycles to prevent monotonic growth.
• Omit the service name when the java agent is also running on the target process (favor using entity guid instead).

v0.5.0

• Update telemetry sdk to 0.8.0
• Minor documentation/readme change.
• Remove use of deprecated sdk methods.
• Small change to how the JFR profile is configured.

v0.4.0

This is a minor incremental release that includes:

• JFR Daemon - If the agent is present, no longer wait for the agent to connect to obtain an entity guid. Instead, buffer the data and wait to send it until the entity guid is available.
• JFR Daemon - Omit the app name from the common attributes when the entity guid is present

v0.3.0

This is an incremental minor release, which includes:

• JFR Daemon - change main class from JFRController to JFRDaemon
• JFR Daemon - now supports fetching entity.guid common attribute from remote MBean
• JRR Daemon - startup delays until service startup is complete
• JFR Daemon - make determining localhost address more robust
• JFR Daemon - retry with backoff when recordings fail
