User Notes:
----------------------------------------

- ### app_dial: Add dial time for progress/ringing.
  The timeout argument to Dial now allows
  specifying the maximum amount of time to dial if
  early media is not received.

- ### app_voicemail: Allow preventing mark messages as urgent.
  The leaveurgent mailbox option can now be used to
  control whether callers may leave messages marked as 'Urgent'.

- ### Stir/Shaken Refactor
  Asterisk's stir-shaken feature has been refactored to
  correct interoperability, RFC compliance, and performance issues.
  See https://docs.asterisk.org/Deployment/STIR-SHAKEN for more
  information.

- ### Upgrade bundled pjproject to 2.14.
  Bundled pjproject has been upgraded to 2.14. For more
  information on what all is included in this change, check out the
  pjproject Github page: https://github.com/pjsip/pjproject/releases

- ### app_speech_utils.c: Allow partial speech results.
  The SpeechBackground dialplan application now supports a 'p'
  option that will return partial results from speech engines that
  provide them when a timeout occurs.

- ### app_chanspy: Add 'D' option for dual-channel audio
  The ChanSpy application now accepts the 'D' option which
  will interleave the spied audio within the outgoing frames. The
  purpose of this is to allow the audio to be read as a Dual channel
  stream with separate incoming and outgoing audio. Setting both the
  'o' option and the 'D' option and results in the 'D' option being
  ignored.

- ### chan_dahdi: Allow MWI to be manually toggled on channels.
  The 'dahdi set mwi' now allows MWI on channels
  to be manually toggled if needed for troubleshooting.
  Resolves: #440

Upgrade Notes:
----------------------------------------

- ### Stir/Shaken Refactor
  The stir-shaken refactor is a breaking change but since
  it's not working now we don't think it matters. The
  stir_shaken.conf file has changed significantly which means that
  existing ones WILL need to be changed.  The stir_shaken.conf.sample
  file in configs/samples/ has quite a bit more information.  This is
  also an ABI breaking change since some of the existing objects
  needed to be changed or removed, and new ones added.  Additionally,
  if res_stir_shaken is enabled in menuselect, you'll need to either
  have the development package for libjwt v1.15.3 installed or use
  the --with-libjwt-bundled option with ./configure.
