Which Elixir version(s) are you (still) using on your non-pet projects?

I am trying to follow new versions of Elixir and Phoenix, refactoring code as needed. So I am at 1.18.2.

1.18.4-otp-27

Just upgraded to 1.18. I try to stay 1 behind current.

Pet project:

Elixir 1.19.1-otp-28

Erlang 28.1.1

Both seem like great releases

We are trying to keep up, though had to skip 1.17 for a bug that never has been fixed in any release if the branch, but actually got backported onto the release support branch.

Now we are working on updating to 1.19 from 1.18, though the deprecation of strict update makes this update non trivial.

We are running a couple small but customer facing applications that are still on Elixir 1.12 since it’s inception. The majority are on 1.15 and our flagship is currently on 1.17 which will soon replace most of the smaller systems, and be upgraded to 1.19 early next year.

Edit: also an internal system still used daily that is running Elixir 1.8 which I haven’t touched since upgrading from 1.7. Can’t believe I forgot it since it’s one of the most critical. If it ain’t broke, don’t fix it as they say.

Current work project:

elixir 1.18.3-otp-27
erlang 27.3.4.2

Most of the time staying on current but sometimes had to stay 1 major version behind.

I think I missed this one, can you give an example or point me to docs?

You missed the deprecation of struct update, without matching on the struct first for the type checker?

In the first RC it was a full deprecation of %S{s | a: :new } but now we have to convince the type checker first that s is indeed an S since the second RC IIRC.

Oh, that. I saw it on the forum but I could not switch to 1.19 at the time. Thanks for the reminder.

What was the proposed workaround?
