Shared Memory is the star of this release IMHO.
Hard to understand why this is so far down. This is fantastic news!
The expansion of f-strings is a welcome addition. The more I use them, the happier I am that they exist https://docs.python.org/3/whatsnew/3.8.html#f-strings-suppor...
One thing I vastly dislike with them is that they are still expanded in logging, while they are not expanded when logging is using "the old way".
Will it print what foo is if I type logger.info("{foo=}")?
> A dictionary type with per-key types.
Ah, I've been waiting for this. I've been able to use Python's optional types pretty much everywhere except for dictionaries that are used as pseudo-objects, which is a fairly common pattern in Python. This should patch that hole nicely.

The way I see it, it's a necessary price to pay, and I just continue to use c-style forming strings in logging.
This is the release that contains the controversial assignment expressions, which sparked the debate that convinced GvR to quit as BDFL. They didn't select my preferred syntax, but I'm still looking forward to using assignment expressions for testing my re.match() objects. I haven't used 3.8.0 yet but I hope its a good one because 2020 is the year that 2.7 dies and there will be a lot of people switching.
Because of the luddites at RedHat, Python2.7 isn't actually dead until 2024. It's infuriating. https://access.redhat.com/solutions/4455511

Is shared memory one of those things that I should try to access/use immediately, or wait for someone to write a wrapper library around, due to the large number of edge cases/strangeness that might occur?
Arguably one of the hotter debated functions is assignment-as-expression through the := or walrus operator. Quite happy with the new SyntaxWarning for identity comparison on literals and missing commas :) Especially neat is also the `python -m asyncio` shell which allows you to run top-level awaits in your repl instead of needing to start a new event loop each time!
