v2.8.0 (2020-07-24)

Features

• Expand variety schema support and add dotted dictionary access.

Device Updates

• Update various vacuum char waveforms with string=True for proper
  handling in typhos.
• Add various missing vacuum PVs to various vacuum devices.
• Switch twincat state device error reset to kind=config so it shows up
  by default in typhos.
• Update LCLS-II imagers to use the new AreaDetectorTyphos.
• The following devices now have lightpath support:
  • FeeAtt
  • FEESolidAttenuator
  • XOffsetMirror
  • PPM
  • XPIM
  • PowerSlits
  • Kmono
  • VRC and all subclasses, such as VGC
  • VFS
• Update XOffsetMirror y_up, x_up, and pitch to
  kind=hinted (previously normal). These axes are usually the
  most important.
• Rename PPM.y_states and XPIM.y_states to target for reduced
  redundancy in screens. The only name is aliased via a property.
• PowerSlits now have a feature set on par with the old slits.
• Update VFS valve_position and vfs_state to kind=hinted
  (previously normal) for more focused statuses.

New Devices

• Add support for Qmini Spectrometer.
• Add AreaDetectorTyphos class for optimized screen view of most used
  area detector signals.
• Add RTDSL0 and RTDSK0 to support the rapid turnaround diagnostic
  station configurations.

Bugfixes

• Fix issue with failing callback in IMS from upstream ophyd change.

Maintenance

• Switch from using cf-units to pint for portability.
• Add the following helpers:
  • interface.LightpathMixin to help establish lightpath support.
  • signal.NotImplementedSignal to help devices that will expand later.
  • signal.InternalSignal to help implement read-only signals that can
    be updated by the parent class.
  • utils.schedule_task to help interface with the ophyd callback
    queues.
• The slits module has been refactored to accomodate both old and new
  slits.
