In addition to several performance enhancements, Sigil-1.9.0 represents a mix of bug fixes and new features. Though this official release is still Qt5 for the Windows and MacOS packages, we've made it possible to build Sigil with Qt6 and will be officially moving to Qt6 in a near-future release. Note that PySide6 will be the new Qt-for-Python of choice for plugins when official Qt6 versions of Sigil are released. We have a plan to make sure the transition of plugins currently using PyQt5 to support both PyQt5 and PySide6 as painless as possible. Stay tuned.
