Oso was not installable on Python 3.12 until release 0.27.2

Export

Oso was not installable on Python 3.12 until release 0.27.2: Upgrade to oso 0.27.2 or newer if you are on Python 3.12; earlier releases simply do not install there.

Upgrade to oso 0.27.2 or newer if you are on Python 3.12; earlier releases simply do not install there. If your lockfile or CI pins oso below 0.27.2 while the interpreter is 3.12, the install failure is the package, not your environment. This was a release-workflow gap, not a code incompatibility, so no policy changes are needed.

Context: Issue osohq/oso#1727 (closed, 4 comments): a reporter found that of 295 dependencies in their project, oso was the only one not installable on Python 3.12. A contributor pushed the release workflow changes needed for 3.12, and maintainer gj confirmed the fix landed in oso 0.27.2 and tested it working on 3.12 locally.

Splunk published v2.0.0 with official Python 3.7+ support, which fixes the 3.12 build failure, and then v2.0.1 to add a missing dependency (the deprecation package) that 2.0.0 forgot to declare. Run: pip install --upgrade splunk-sdk and make sure you land on 2.0.1 or newer. The original reporter confirmed v2.0.1 installs and runs clean on Python 3.12, then closed the issue as resolved.

Plaid regenerated the client with openapi-generator 6.1 and released it the same week - the maintainer confirmed it passed the test suite and planned a Tuesday release. Fix: upgrade plaid-python past the 12.0.0-era release to the regenerated version. There was no usable workaround - the reporter needed to read transfer responses to store transfer info.Read skill →
