No, but in most cases, we can semi-automatically update lv_micropython by running a single command.
As @amirgon mentioned…
The last major release of Micropython was in December 2019. As such, the latest merge with MicroPython occured on Jan 17th.
If you’d like to update lv_micropython manually, you should be able to clone it and then run the following commands:
git remote add micropython https://github.com/micropython/micropython.git
git fetch micropython
git merge micropython/master
It’s quite possible you’ll have to resolve some merge conflicts but that will give you all of the latest changes in Micropython.
