Aug 1, 2025August 2025 focused on preparing a stable 3.10.x release line for matplotlib, strengthening cross-backend reliability, and improving developer/user-facing documentation. Highlights include consolidating and publishing release-management work for 3.10.x (culminating in v3.10.6 with updated release notes, milestones, and citations), backporting and stabilizing HiDPI handling in the Qt backend across X11/Windows (Qt 6.6+), improving user experience by gracefully handling ImportError in Tkinter with python-build-standalone, and hardening FigureCanvasQT with robust widget-size checks and updated test dependencies. These efforts improve release velocity, user experience on high-DPI displays, and overall backend robustness.
