Official support of Python 3.14 #143
Description
Activity
DuckDB 1.4.2 will have Python 3.14 support (see PR). You can keep this issue open if you like and we'll close it at some point, but it's likely you'll notice the 1.4.2 release long before we close this issue so I don't recommend treating this issue as a "release announcement" event queue ;-)
Reacted by Edgar Ramírez Mondragón and Michael HarrisReacted by stonebig@evertlammerts thanks for the heads up. I'll keep this open for others if they're interested in the status of official 3.14 support and will mark it as closed when 1.4.2 is released if no one else has 👍
I think the support is there now to have prebuilt binaries for it right? pyarrow was updated to support it recently
duckdb 1.4.2 is installing in python 3.14 for me now, thanks all!
Reacted by Michael Harris and Saksham GoyalCI should prepare for py3.15 too. dont wait till the last moment for support. keep tracking it even if it fails.
afaik there are lots of deprecations coming up so there may need to be changes.- added a commit that references this issue

Note: This should not be marked as a duplicate of #139 because the request is official support beyond nightly/pre- builds.
Specifically, this comment #139 (comment) mentions that this is not officially supported but the issue has been closed.
I'd like an issue that stays open until official support is added so I can subscribe and be notified when that happens.
