# Change Log
All notable changes to this project will be documented in this file.

This project uses [PEP440] versioning where released versions start with 3 dot
separated numbers (`MAJOR.MINOR.PATCH`), which should be interpreted as 
their homonym components in [Semantic Versioning]. 

This file follows the formats and conventions from [keepachangelog.com]

Note: changes in the [support-3.x] branch (which was split from 
the master branch after [3.7.1] and maintained in parallel to the 
develop branch) won't be reflected in this file.


## [5.0.0] - 2021-11-15 

Major release that removes support of Python2 and Qt4 (from here we support 
python >= 3.5 and the PyQt5 and PySide2 bindings). Other than that there should 
not be any other backwards incompatibility between 5.x and 4.x (we 
intentionally avoided enforcing the pending deprecations of 4.x even if this 
is a major version bump)

### Removed
- python2 support (use python >= 3.5 instead) (!1192)
- Qt4 (PyQt4 and PySide) support (use PyQt5 or PySide2 instead)
- `taurus.qt.qtgui.qwt5` (use taurus_pyqtgraph instead)
- `taurus.test.testsuite` (use pytest instead)

### Added
- Support for loading settings from user and system .ini files (!1205)

### Changed
- extensive refactoring to clean taurus code. It is now flake8 and 
  black compliant. Tests enforce in CI for flake8 and black (!1193)
- refactor import hierarchy in Taurus. Official API is now defined via
  inclusion in `__all__` variables (!1199) 
- docstrings now use standard reST formatting (removed custom taurus
  preprocessing of docstrings) (!1193)

  a widget class (!1217):

  - the class name in taurusgui's `*Description` classes
  - the `defaultCandidates` and `extraWidgets` values in `WidgetPage`
  - The widget name in DockWidgetPanel.setWidgetFromClassName()
- `tauruspluginplugin` uses an explicit list of widgets instead of 
  introspection (!1217) 
- `taurusdemo` uses an explicit list of submodules instead of 
  introspection (!1217)
- all usages of deprecated `imp` module replaced by `importlib` equivalents
- Pending operations check now compares quantities allowing for rounding 
  errors (!1195)
- `QtWebkit.QWebView` replaced by `QtWebEngineWidgets.QWebEngineView` 
  (!1209, !1213)
