release: published 5.10.0

### 5.10.0 (2019-06-11):

* The agent now allows installation on node v11 and v12.

  This change relaxes the engines restriction to include node v11 and v12. This does
  not constitute official support for those versions, and users on those versions
  may run into subtle incompatibilities. For those users who are interested in
  experimenting with the agent on the v11 and v12, we are tracking relevant issues
  here: #279.

* Lambda invocations ended with promises will now be recorded properly.

  Previously, the lambda instrumentation was not intercepting the promise
  resolution/rejection returned from a lambda handler. The instrumentation now
  properly observes the promise, and ends the transaction when the promise has
  finished.

* Lambda invocations will only attempt to end the related transaction a single time.

  In the event of two lambda response events (e.g. callback called, and a promise
  returned), the agent would attempt to end the transaction twice, producing an
  extraneous empty payload. The agent now limits itself to a single end call for
  a given transaction.

* The agent will now properly end transactions in the face of uncaught exceptions
  while in serverless mode.

* Enables ability to migrate to Configurable Security Policies (CSP) on a per agent
  basis for accounts already using High Security Mode (HSM).

  When both HSM and CSP are enabled for an account, an agent (this version or later)
  can successfully connect with either  or the appropriate
   configured.  has been added as part of
  the preconnect payload.
