ta-lib 0.7.0 using C-wrapper 0.6.4 (?)

[xmatthias]

Updating to ta-lib-python 0.7.0 seems to still use the underlying ta-lib 0.6.4.

Upgrade to latest TA-Lib upstream C library v0.7.1 release

from the Release page for ... the below however seems to disproof this (or reports a wrong version).

Reproduction:

mkdir /tmp/ta-lib-tests
cd /tmp/ta-lib-tests
uv venv
. .venv/bin/activate
uv pip install ta-lib==0.7.0

python -c "import talib; print(talib.__version__);print(talib.__ta_version__)"

output:

❯ python -c "import talib; print(talib.__version__);print(talib.__ta_version__)"
0.7.0
b'0.6.4 (Jul 3 2026 22:58:17)'

This might be a missing version statement somewhere (assuming the new c library is still linked) - but it's still kindof confusing ...

Oops? Must have been an issue on the CI wheel builder.

[xmatthias]

You're right - the variable $TALIB_C_VER is set in CI - but not passed to the ci-buildwheel containers (they miss in CIBW_ENVIRONMENT_LINUX - and the corresponding other system variables).
that makes the build script fall back to 0.6.4 (via

ta-lib-python/tools/build_talib_linux.sh

Line 3 in d1adb26

TALIB_C_VER="${TALIB_C_VER:=0.6.4}"

)

Would you mind confirming the latest release 0.7.1 has it for you?

0.7.1 seems to work fine - tested on linux arm and amd64 architectures.

Thanks for the quick fix!
