This is Python, your daily developer briefing for July 11th, 2026.
The dominant story today is tkinter. Serhiy Storchaka and collaborators pushed a wide-ranging modernization effort across the module, and it's worth understanding as one connected campaign rather than isolated patches.
First, new capability: tkinter gained a font chooser dialog in PR 153255, a system tray and notifications interface in PR 153260, and print support for canvas and text widgets. These bring tkinter closer to what native Tk 8.7 and 9.0 already offer.
Second, correctness. PR 152310 finally gives the tkapp and timer token objects proper garbage collection support, closing a reference-cycle leak that an earlier attempt had to revert. PR 153514 changes how Tcl object types convert to Python, returning real strings and numbers instead of opaque wrapper objects, which…
Taken together, this is a maintainability push: fixing decades-old rough edges — some issues here date back to 2008 and 2011 — while keeping backward compatibility through deprecation warnings, as seen in the PanedWindow parameter rename and the deprecated askopenfiles function.
Second theme: infrastructure. Vstinner's PR 153416 and its backport…
