- #548: Adds a disconnect() function that allows to conditionally disconnect signals,
including after reload.
Also, a SignalBlock class used to temporarily block a signal-slot pair
- #557: Allow console stack to be set outside of exceptions (see also: pg.stack)

API / behavior changes:
- Deprecated graphicsWindow classes; these have been unnecessary for many years because
widgets can be placed into a new window just by calling show().
- #158: Make DockArea compatible with Qt Designer
- #406: Applying alpha mask on numpy.nan data values
- #566: ArrowItem's `angle` option now rotates the arrow without affecting its coordinate system.
The result is visually the same, but children of ArrowItem are no longer rotated
(this allows screen-aligned text to be attached more easily).
To mimic the old behavior, use ArrowItem.rotate() instead of the `angle` argument.
- #673: Integer values in ParameterTree are now formatted as integer (%d) by default, rather than
scientific notation (%g). This can be overridden by providing `format={value:g}` when
creating the parameter.
- #374: ConsoleWidget uses the console's namespace as both global and local scope, which
- #410: SpinBox siPrefix without suffix is not longer allowed, select only numerical portion of text on focus-in
allows functions defined in the console to access the global namespace.
- #479,521: ParameterTree simple parameters check types before setting value
- #555: multiprocess using callSync='sync' no longer returns a future in case of timeout
- #583: eq() no longer compares array values if they have different shape
- #589: Remove SpiralROI (this was unintentionally added in the first case)
- #593: Override qAbort on slot exceptions for PyQt>=5.5
- #657: When a floating Dock window is closed, the dock is now returned home
- #771: Suppress RuntimeWarning for arrays containing zeros in logscale
- #942: If the visible GraphicsView is garbage collected, a warning is issued.
- #958: Nicer Legend
- #963: Last image in image-stack can now be selected with the z-slider
- #992: Added a setter for GlGridItem.color.
