What is the python update policy, going from 3.9.1 to 3.9.2 to ...

[FonsRademakers]

Hi,

is the python upgrade from 3.9.1 to 3.9.2 considered a patch level upgrade preserving binary compatibility? I noticed that the python 3.9.1 include directories disappeared when I did a brew update and got python 3.9.2. Is the link to python/3.9/... valid for the whole serie 3.9.*? I have some pre-build binaries build against python 3.9.1 that I ship for brew based systems for which I require python 3.9. Or should I re-build all these binaries with 3.9.2?

Thanks, Fons.

Binary compatibility should work fine for patch level updates.

If linking against brewed Python, ensure you are using the /usr/local/opt prefix rather than /usr/local/Cellar to avoid links breaking on upgrades.

So:

/usr/local/opt/python@3.9/Frameworks/Python.framework/Versions/3.9

instead of:

/usr/local/Cellar/python@3.9/3.9.2_2/Frameworks/Python.framework/Versions/3.9

(Formulae do this automatically.)

The general site-packages directory, if that's all you need, is found at:

/usr/local/lib/python3.9/site-packages

This all assumes the standard Intel Homebrew prefix of /usr/local.

Thanks for the clarification. i posted a few days ago a question (#1071) on the best way to obtain this link without patch level number, is there a way to get this just using the python3 binary?

Why doesn't this work? #1071 (comment)

Sorry guys, I overlooked that you had fixed my example in the meanwhile. Thanks!
