[sbourdeauducq]

Is this release going to have Python >=3.11 by default ?

[Atemu]

Yes. In fact that sort of already happened: #251878 (part of #257792).

[figsoda]

The date for restricting breaking changes to Release Critical Packages has been delayed for #241692 (llvmPackages: 11 -> 16 on Darwin and Linux), in particular we are waiting for #253031 and #253009

[figsoda]

Breaking changes to Release Critical Packages are now restricted. That means the following packages should not receive any more breaking changes:

• binutils
• gcc
• glibc
• llvm
• systemd

Note that some breaking changes are still in the staging branch, so the master branch will still receive these changes once they are merged in, but other new breaking changes should be held off until branch-off.

[TheRealGramdalf]

Apologies if this is the wrong place to ask (yes, I've looked at the Gnome 44 -> 45 PR), but is Gnome 45 aimed for release along with 23.11? I ask primarily because of Gnome Extensions.

[vcunat]

Yes, it is.

[LunNova]

@figsoda @RaitoBezarius Looking for input on whether it would be appropriate to merge at this point. It's not intentionally breaking but the answer may still be no as there's risk?

#259070 (comment)

[figsoda]

Breaking changes are now restricted with the exception of desktop environments.

[figsoda]

The first staging-next merge into master has been delayed since it is still not yet ready to be merged. Depending on how things go, it is possible that #263535 will be the last staging cycle of this release period, combining the 2023-11-13 and 2023-11-20 checkpoints.

[mastermach50]

Will this release support secure boot out of the box?

[Janik-Haag]

No but you can watch #263713 for progress.

[figsoda]

Branch-off has been postponed since the current procedure doesn't work with the recently added branch protection rules. We will try again tomorrow if we manage to get in contact with one of the repository admins.

Where can I find the instructions to upgrade from nixos 23.05 to 23.11

Also should I just remove the code that I was using to install some packages from the previous unstable aka 23.11

sample from my configuration.nix

{ config, pkgs, lib, ... }:
let 
  sources = import ./nix/sources.nix;
  lanzaboote = import sources.lanzaboote;
    
  unstable = import
    (builtins.fetchTarball https://github.com/nixos/nixpkgs/tarball/master)
    # reuse the current configuration
    { config = config.nixpkgs.config; };
in
{
...
}

[mastermach50]

@drakon64

I did see that article but it seems old as it still refers to 23.05 as the current stable. Should I still follow it?

[drakon64]

@mastermach50 Change the channel name to nixos-23.11 and you should be good.

nix-channel --add https://channels.nixos.org/nixos-23.11 nixos
nix-channel --update nixos

Then the usual update commands
