Node.js agent v4.1.1

Improvements

• Optimized unhandledRejection reporting when using async_hooks.
• Replaced all uses of util._extend with Object.assign.
• Completed TODOs regarding the Node 0.10 and 0.12 deprecation.
• Added PriorityQueue serialization benchmarks.

Bug fixes

• The agent no longer resizes the metric timeslice start time to be the earliest start time of the transactions that finish during the timeslice.

• Background transactions created may now be named through API#setTransactionName.

  Previously, the agent didn't respect the transaction naming precedence for background transactions. Background transaction naming behavior is now in line with web transaction behavior.

• Logger no longer tries to create very large log messages.

  When a message is created that would be too large to log, a process warning is emitted.

• The agent will now respect event count limits when merging data from a failed send.

  Previously, when merging data into an event pool the agent wouldn't maintain the size limit of the reservoir.

• Added check for a route prefix when wrapping Hapi route handlers.

  Previously, route prefixes specified via plugin options weren't being included in transaction names. Now, if the agent finds a route prefix associated with a given realm, it is prepended to the route path in the transaction name.
