Version 0.4.0 - Technical Release Notes
Highlights:
This update focuses on cross-version compatibility between QGIS 3.x
(Qt5) and the upcoming QGIS 4.x (Qt6/Master), ensuring a stable
transition and fixing critical API mismatches.

Changes & Fixes:

Qt6/QGIS 4 Compatibility:

Migrated all core UI imports to use the qgis.PyQt wrapper, ensuring
the plugin dynamically selects between Qt5 and Qt6.

Updated Enums and Constants namespaces to comply with Qt6 strict
typing (e.g., moved Window flags to Qt.WindowType, Ok buttons to
StandardButton, and ActionRole to ButtonRole).

Fixed ModuleNotFoundError by implementing a universal import strategy
for the sip module across different Python environments.

API Enhancements & Bugfixes:

QgsLayoutItemMap: Removed calls to the non-existent
setLayerSourceByExpression method, replacing it with the official
setLayers and setSubsetString logic for feature filtering.

QgsLayoutItemLabel: Implemented a compatibility bridge for ContentMode
(ModeHtml), ensuring consistent HTML rendering in both QGIS 3.40 and
3.99+.

Memory & Stability:

Implemented safer object destruction in the unload() method using
sip.isdeleted() checks to prevent "C++ object already deleted"
crashes.

Replaced the deprecated QDesktopWidget with
QApplication.primaryScreen() for modern multi-monitor support and
high-DPI scaling compatibility.

Build System:

Updated resources.py and UI loading logic to prevent hardcoded PyQt5
dependencies.
