New release for Python 3.13

[lesleslie]

Question

Hello,

Wondering when we can expect a new release compatible with Python 3.13?

I see the commit for the Python 3.13, and am able to install it using git+https://github.com/jcrist/msgspec.git, but unfortunately I can't publish any packages to pypi that depend on msgspec until a new official release has been published to pypi. Am hoping for a new release soon that incorporates the Python 3.13 support (without freethreading for now).

Thank you!

As a temporary workaround I created a package with python 3.13 support. I wouldn't expect this to be updated or maintained beyond this point but give it try if you like. It will be deleted once a new official release comes out.

msgspec-python313-pre

pdm add msgspec-python313-pre or whatever (make sure to remove msgspec - this is a drop in replacement)

@jcrist hi, what are current plans about publishing release?

It seems like he is currently working on adding free-threading support, so my only assumption would be that he wants to release the new version with it already included. Reference. I also think some communication on these issues wouldn't hurt!

I'm pretty sure the maintainers know of the community excitement around 3.13 and adding more "+1" messages will not help. Maintainer attention is a scarce resource, please be considerate. Many of us are subscribed to this issue for updates. Peace and love 🕊️

Really love mesgspec but without python 3.13 its not any longer an option .. distros with rolling releases started to switch to Python 3.13 .. ArchLinux is one -> and our applications did stop working ..

I'm pretty sure the maintainers know of the community excitement around 3.13 and adding more "+1" messages will not help.

Fully understand .. especially as I am a developer myself, but leaving such major problems uncommented is not a solution either

-> users now have to deal with broken applications ..

I apologize for the harsh tone, but I wanted to make it clear: We need a timeline!

msgspec 0.19.0 has been released with support for Python 3.13. The full changelog may be found here.

Thank you everyone for your patience. Closing.
