========================
This is a new release including a bunch of bug fixes and a couple of new features.

New Features
--------------
* Better error reporting for embedded display when embedded file is not found in Qt Designer. (Thanks ivany4)
* New functionalities for ExternalTools: `use_without_widget` and tool filtering based on widget.
* New property at TemplateRepeater to control spacing. (Thanks mattgibbs)
* Update contributors list. (Thanks mattgibbs)
* Update license year. (Thanks mattgibbs)
* Add exception hook when running Qt Designer to avoid crashes.
* Add two new properties to plots for X and Y labels at axes.
* Tooltip pointing users to Curve Editor at Plot Widgets.

Documentation
-------------
* Add missing documentation for environment variables (Thanks ivany4)
* Add entry for Plot Curve Editor.

Bug Fixes
----------
* Don't crash designer when `base_path` is not set for embedded display widget. (Thanks ivany4 )
* Precision could be ignored if it was parsed before `precisionFromPV` in the UI file. (Thanks ivany4)
* Use full filename instead of `fname` for embedded display widget.
* loadWhenShown in Qt Designer loses embedded widget. (Thanks ivany4)
* Value should not be reset in Qt Designer when changing DisplayFormat of precision. (Thanks ivany4)
* Prevent PyDMScaleIndicator from crashing when receiving None. (Thanks ivany4)
* Prevent PyDMSpinBox from crashing when receiving None. (Thanks ivany4)
* Separate precision from channel from precision from user defined property.
* Fix slider problems. (Thanks mattgibbs)
* Fix waveform plot bug that prevented constant waveforms from ever getting plotted. (Thanks anacso17 and mattgibbs)
* Fix psp plugin string handling for Python 3. (Thanks mattgibbs)
* Several channel connection fixes. (Thanks mattgibbs)
* Fix template repeater against invalid JSON.
* Disable `autoSIPPrefix` for TimePlot.

Deprecation
-----------
* Python 2.7 for Windows is no longer supported/tested. Use at your own risk.

======================
This is another small, mostly bug fix release.

New Features
--------------
* PyDMImageView has a new `showAxes` property to add X and Y axes to the side of the widget. There are also two new properties to set a scale factor for the X and Y axes - this can be useful if you want to convert from pixel units to real-space units like millimeters.

Bug Fixes
----------
* PyDMShellCommand buttons no longer execute the command when you right-click the button.
* When you remove a curve from any of the plotting widgets, the channels for that curve are now properly disconnected. (Thanks hhslepicka!)
* Fix a crash in PyDMEmbeddedDisplay introduced in v1.7.2.

======================
This is mostly a bug fix release, with a few small improvements.

New Features
--------------
* PyDMEnumButtons can now be used with plain-old (non-enum) integer-valued channels. Just set the 'items' property in Qt Designer or in Python code with a list of strings, one per integer value you expect. (Thanks ivany4)
* PyDMEmbeddedDisplays will now automatically re-load the file if the 'macros' property changes.

Bug Fixes
----------
* Don't expand $PYQTDESIGNERPATH in the PyDM Conda recipe. (Thanks teddyrendahl)
* Fixed a crash when supplying a negative integer to the 'shift' property on PyDMByteIndicator. (Thanks ivany4)
* Fixes for CI on Windows. (Thanks hhslepicka)
* Crosshairs on the plotting widgets can now be deselected. (Thanks fernandohds564)
* PyDMMainWindow now properly adds a new item to the history stack when you navigate to a file that has the same filename, but different macro variables.
* Fixed a logic error that would sometimes prevent a PyDMEmbeddedDisplay from ever loading the file.
* Fixed a bug where PyDMEmbeddedDisplay would sometimes skip searching directories specified by the $PYDM_DISPLAYS_PATH environment variable
* PyDMRelatedDisplayButton no longer uses the deprecated 'displayFilename' property to store the filename a user specified in the initializer. This doesn't change the behavior of the widget, but does get rid of some annoying deprecation warnings.
* Fixed a bug introduced in v1.7 where PyDMSlider would get stuck in a disabled state if the user specified their own limits (Thanks hhslepicka)
