The main purpose of this release is to fix a regression introduced in 3.3.4 (#1627).

Installation

• Windows: download and execute thonny-3.3.5.exe. You may receive a warning dialog from Defender until it gains more reputation. Just click "More info" and "Run anyway".
• macOS: download and open thonny-3.3.5.pkg and follow the instructions. NB! While using Thonny you may be asked for permission to use Desktop or Documents. Make sure you grant the permission, othewise Thonny can't work in that folder!
• macOS Big Sur: thonny-3.3.5.pkg may work, but if you are having problems, then try thonny-3.3.5_alt.pkg. This one has universal build of Python 3.9 (instead of 3.7) and newer Tk (8.6.11 instead of 8.6.8).
• Linux: download thonny-3.3.5.bash and execute it with Bash (bash thonny-3.3.5.bash)

thonny-xxl variants have more packages preinstalled.

Changes since 3.3.4:

• Fix too short reprs at MicroPython REPL (regression introduced in 3.3.4), #1627
• Fix incorrect presentation of long output lines, #1628
• Fix error in nicer debugger when stepping in generators, #1631
• Fix infinite recursion error when evaluating globals() in MicroPython REPL while object inspector is open, #1641
• Update Greek translation

This is mostly a bug-fix release.

Changes since 3.3.3:

This release adds support for MicroPython on the new Raspberry Pi Pico (https://www.raspberrypi.org/blog/raspberry-pi-silicon-pico-now-on-sale) and fixes some bugs.

I can now finally say, that all the work on Thonny's MicroPython support since early betas of 3.3 was supported by Raspberry Pi Foundation. Many thanks to them!
