Stan.jl v10.8.4 Released — CmdStan 2.37 Support and Ecosystem Refresh
We’re happy to announce the release of Stan.jl v10.8.4.
This release brings the Stan.jl ecosystem to CmdStan 2.37, giving the Julia community access to newer Stan features and improvements from the 2.37 release series. After completing that work, focus will shift to support for CmdStan 2.38.
What’s Included in Stan.jl v10.8.4
Key updates:
- Upgraded CmdStan support to 2.37
- Refreshed project dependencies to latest compatible versions
- Additional dependency updates (including
DimensionalData) - Release alignment and maintenance improvements
Closed issues also included discussion around future branching strategy and consolidation of prior compatibility PRs.
Coordinated Ecosystem Releases
This update also included synchronized releases across the StanJulia package family:
- StanBase.jl v4.12.3
- StanDiagnose.jl v4.5.4
- StanOptimize.jl v4.4.4
- StanSample.jl v7.10.3
- StanPathfinder.jl v1.0.2
- StanVariational.jl v4.5.3
- StanQuap.jl v4.4.3
- DiffEqBayesStan.jl v3.2.3
This was a coordinated ecosystem refresh to ensure compatibility across the Julia + Stan stack.
What’s Next
The next planned release will introduce a new package bringing Stan’s Laplace approximation capabilities from CmdStan into the StanJulia ecosystem.
This will complete our broader CmdStan 2.37 feature adoption and provide Julia users direct access to Stan’s newer approximation workflows.
After that, focus will shift toward CmdStan 2.38 and future Stan improvements.
Why This Matters
We remain committed to keeping Stan.jl modern, maintained, and aligned with upstream Stan so Julia users can continue using best-in-class Bayesian tooling.

If you use Stan from Julia, now is a great time to update, test, and share feedback.
Looking forward to hearing from all of you.
We also want to sincerely thank the community for its patience while these coordinated updates were completed across the StanJulia package ecosystem.
