Version alignment

tet-py releases pin a specific tetration crate version at build time. Python API version and Rust core version are reported separately.

Current releases

Component	Version
tet-py (PyPI)	0.1.1
tetration crate (linked)	0.1.9
Layout version	1
C ABI version	1 (TET_ABI_VERSION)
Python	3.11+ (abi3 wheels)
NumPy	2.x

Alignment policy

tet-py	tetration crate	Notes
0.1.0	0.1.9	Initial PyPI release; query + NumPy ram/spill/sidecar + f32/f64 write
0.1.1	0.1.9	Query preview: preview=N, QueryResult.preview

• Patch tet-py releases may bump the pinned crate for bug fixes.
• Minor tet-py releases may add Python API or query wrappers without layout changes.
• Layout v1 and query JSON/TOML may still change before 1.0 — pin versions in production.

Checking versions

Python:

import tet
print(tet.__version__)      # tet-py package version
print(tet.core_version())   # tetration crate compiled into the extension

CLI:

tet --version

Rust (when embedding directly):

[dependencies]
tetration = "0.1.9"

C ABI:

#include "tetration.h"
assert(tet_abi_version() == TET_ABI_VERSION);

Upgrade notes

When upgrading tet-py:

1. Check the tet-py releases page for the pinned tetration version.
2. Re-run tests that depend on query wire shape or materialized dtypes.
3. If you also embed Rust directly, keep the same tetration minor as tet.core_version() unless you know the diff is compatible.

TIP

Watch tetration releases for layout and query engine changes that affect both the CLI and tet-py.
