Changes since 3.3.13

Breaking changes

• Drop support for Python 3.5, 3.6 and 3.7
• Require single click for toggling a breakpoint, #2293
• Clear Shell before starting new process (Run, Debug, Stop/Restart, ...) by default. Can be turned off in Tools => Options => Shell, #1681
• Rename "Python 3" back-end to "Local Python 3"
• Don't SetProcessDpiAwareness for user programs anymore. This means for example, that Tkinter and Pygame programs on Windows run as if they were executed with plain Python (ie they may become blurry on modern displays). For clear picture, start your program with import ctypes; ctypes.OleDLL("shcore").SetProcessDpiAwareness(1), #2159
• Drop support for jedi versions below 0.18.1

Distribution

• Upgrade bundled Python to 3.10
• The main Windows bundle is now 64-bit. For fallback publish 32-bit bundle with Python 3.8 for 32-bit Windows 10 and 8.1 and all variants of Windows 7 and 8.

• Stop publishing 32-bit Linux bundles.
• Enhance Linux installer script (the .bash-file) to create a venv and pip-install Thonny if run on a platform for which there is no binary bundle available. This means you can now use Linux installer also on Raspberry Pi, #1736

Code completion and analysis

• Add the option for automatically getting completions while typing (Tools => Options => Editor)
• Selecting a completion with Tab now replaces the name suffix right of the cursor, #1998
• Turn off requesting completions with Tab in editors by default, #2069
• Show documentation for the selected completion with another Ctrl-Space or automatically (Tools => Options => Editor)
• Add "call-tips" -- a box describing the formal parameters of current method call. Invoke manually with Ctrl-Shift-Space or automatically after typing open parentheses (Tools => Options => Editor)
• Enhance Go-to-definition (Ctrl-click). The name is now underlined while ctrl-hovering over it.

MicroPython / CircuitPython

• Add LEGO® EV3 back-end: "Run => Select interpreter => MicroPython (EV3)"
• Support CircuitPython with micro:bit, #2251
• Use pipkin for managing packages on MicroPython and CircuitPython devices. This enables proper listing of packages together with version info and proper uninstallation.
• Use .local_rtc config parameters instead of (oppositely worded) .utc_clock in MicroPython back-ends, 116aecd
• Present MicroPython time options (whether to sync time and whether to use local time) in back-end configuration page, #1638
• Automatically interrupt current process when connecting to bare-metal MicroPython or CircuitPython device. This can be turned off at device's settings page, #2059
• Don't hide the output when Stop/Restarting MicroPython, #1805
• Make internal MicroPython errors less intimidating. In several cases the errors are caused by bugs in MicroPython or USB driver and there is no use of showing the stacktrace. User is now directed to restart the device and stacktrace can be checked from the backend.log, #1799
• Make MicroPython back-end advise Ctrl+C also if only whitespace characters get printed, #1755
• Allow running MicroPython scripts without soft-rebooting first, #1565, #1716

• Mention the possibility to reconfigure file types when denying opening remote files in a system app, #2148
• Refactor MicroPython/CircuitPython flashing dialog, #2344
• Add separate "Install ..." items to the back-end switcher menu if a device in UF2 bootloader mode is detected, #2387
• Use "Install MicroPython" instead of "Install firmware", #2364
• Take OSC commands into account when looking for prompts (relevant for CircuitPython 8), #2349
• Disable "Run" command when MicroPython device is disconnected
• Update completion stubs for MicroPython and CircuitPython (from @hlovatt and @adafruit)
• Make Shell read-only when device is disconnected
• Fix various problems with managing files on CircuitPython devices
• Don't assume all CircuitPython boards have RTC, #1760

• Improve icon scaling -- use larger icons when Treeview row height is larger than general.large_icon_rowheight_threshold
• Use default font in Treeviews (including Files and Variables view). Therefore Treeview's font size is now affected by the scaling factor and is not affected by editor font size.
• Use isolated mode for launching Thonny. This includes hiding user-site packages from Thonny's GUI process (not from user programs). Plug-ins now get installed under Thonny's data folder, #2038, #1651
• Allow installing packages for remote CPython backend, #1319
• Flatten the list of interpreters in the backend-switcher menu (lower-right corner of the main window)

• Merge "The same interpreter which runs Thonny" and "Alternative Python 3 interpreter or virtual environment" back-ends into "Local Python 3"
• Back-end switcher now remembers several configurations for remote CPython and MicroPython.
• Make package manager work for remote Python 3 (SSH)
