Hi Gabor, Thanks for bringing this up. In my opinion, it is a bit aggressive to directly drop Python 3.7 in 1.19. Python 3.7 is still used a lot[1], and as far as I know, many Pyflink users are still using python 3.7 as their default interpreter. I prefer to deprecate Python 3.7 in 1.19 just like we deprecated Python 3.6 in 1.16[2] and dropped Python 3.6 in 1.17[3].
For the support of Python 3.11, I am very supportive of the implementation in 1.19 (many users have this appeal, and I originally wanted to support it in 1.18). Regarding the miniconda upgrade, I tend to upgrade miniconda to the latest version that can support python 3.7 to 3.11 at the same time.
