v4.3.0 (2021-04-02)

API Changes

• Deprecate pcdsdevices.component in favor of pcdsdevices.device
  to avoid circular imports and to more closely mirror the structure of
  ophyd.

Features

• Add FuncPositioner as a replacement for VirtualMotor.
  This is a "dirty" positioner intended for quick hacks
  in the beamline setup files, instantiated via handing
  various functions to the init.
• Add EpicsSignalEditMD and EpicsSignalROEditMD classes for
  situations where you need to override the control system's
  discovered metadata.
• Adding a normally open class (VRCNO) for VRC gate valves to valve module. VRCNO extends VVCNO and adds VRC functionality.
• Add SyncAxis to replace deprecated SyncAxesBase with expanded
  feature set, more sensible defaults, and more solid foundation.
• Add set_current_position to all PseudoPositioner classes.
• Add invert parameter to DelayBase for inverting any delay stage.
• Add set_position as an alias to set_current_position
• New motor configuration for LAMP. Hoping we only have two configurations to switch between
• Add InterfaceDevice and InterfaceComponent as a tool for
  including pre-build objects in a device at init time.
• Add to_interface helper function for converting normal Device
  classes into InterfaceDevice classes.
• Add ObjectComponent as a tool for including pre-build objects in
  a device at class definition time.

Device Updates

• Add custom status prints for DelayBase and SyncAxis
• QminiSpectrometer: A few variety metadata updates for Typhos screens.
• Set EpicsMotor soft limit kinds to "config" for use in typhos.

New Devices

• QminiWithEvr: A new class with added PVs for controlling an EVR from a
  Typhos screen.
• LAMPMagneticBottle
• XOffsetMirrorState for mirror coatings

Bugfixes

• Include hacky fix from XPP/XCS that allows LaserTiming to complete moves
  in all situations. The real cause and ideas for a clean fix are not
  currently known/explored.
• Fix issue where Newport motors would not show units in their status prints.
• Fix issue where SyncAxis was not compatible with PseudoPositioners as
  its synchronized "real" motors.
• Fix an issue where calling set_current_position on certain motors would
  cause the ipython session to freeze, leaving the motor in the set state
  instead of bringing it back to the use state.
• Hacky workaround for IMS motor part number strings being unable to be read
  through pyepics when they contain invalid utf-8 characters.
• Fix issue where Newport user_readback had incorrect metadata.
• :class:~pcdsdevices.signal.UnitConversionDerivedSignal will now pass
  through the units keyword argument in its metadata (SUB_META or
  'meta') callbacks. It will be included even if the original signal
  did not include units in metadata callbacks. (#767)
• Fix an issue where various special Signal classes had their kinds
  improperly reported as "hinted".

Maintenance

• Make unit handling in status_info more consistent to improve reliability of
  status printouts.
