After more than six months, the conda-forge team and contributors have
managed to update the Qt5 packages to the latest LTS version, 5.15.2.
Major changes include separating the package for QtWebEngine
(qt-webengine) from the rest of Qt (now in a new package called
qt-main). This allows recipes that do not use any of the WebEngine
components to depend only on qt-main, reducing the total size of the
downloaded binaries. As a result of this, qt will be a metapackage
that installs both qt-main and qt-webengine as dependencies.
With respect to PyQt, the new packages now are in sync with respect to
their corresponding PyPI releases, which means that the pyqt package
will only provide the core components of Qt, leaving pyqtwebengine and
pyqtcharts as optional packages that extend PyQt by providing the
QtWebEngine and QtCharts components, respectively. A migrator will be
put in place to help with the transition.
