Allow wrapt 2.x: the ^1.11.2 bound conflicts with environments on the current wrapt line #861

Expected Behavior

datadog-lambda can be installed together with wrapt 2.x.

wrapt 2.x is the actively developed line: 2.0.0 shipped in October 2025 and 2.5.0 in September 2026, and the last final 1.x release is 1.17.3 (August 2025).

ddtrace supports wrapt 2 since the fixes for DataDog/dd-trace-py#14993: current 4.x releases declare wrapt>=1,!=2.2.0,<3. Widening the bound in pyproject.toml to match would allow it:

wrapt = ">=1.11.2,!=2.2.0,<3"

Actual Behavior

datadog-lambda declares wrapt = "^1.11.2", which Poetry publishes as wrapt>=1.11.2,<2.0.0.

The bound is unchanged in the latest release (8.128.0) and on main (8.129.0.dev0).

Projects that move their dependency set to wrapt 2.x, for example through a lockfile or a constraints file shared across services, can no longer install datadog-lambda. The only workarounds are holding the whole environment on wrapt 1.x, or installing datadog-lambda with --no-deps.

The bound appears to be Poetry's default caret rather than a deliberate cap. wrapt (>=1.11.2,<2.0.0) is already present in 5.85.0 (2023-12) and 6.99.0 (2024-10), before wrapt 2.0 existed.

wrapt 2 does work in practice:
datadog_lambda uses only wrapt.wrap_function_wrapper and wrapt.importer.when_imported (datadog_lambda/patch.py). Both are still available in wrapt 2.x, and datadog_lambda calls them positionally the same way as before. With wrapt installed over the declared bound, on CPython 3.14.7:

• datadog-lambda 8.128.0, ddtrace 4.15.3, wrapt 2.5.0: datadog_lambda.patch.patch_all() wraps requests.Session.send, and a handler decorated with datadog_lambda.wrapper.datadog_lambda_wrapper runs and returns normally.
• datadog-lambda 8.123.0, ddtrace 4.14.0, wrapt 2.4.1: same result, and the handler emits aws.lambda.enhanced.invocations.

Steps to Reproduce the Problem

1. Create a fresh virtual environment with Python 3.10 or later.
2. Run pip install "datadog-lambda==8.128.0" "wrapt==2.5.0".
3. pip refuses the install with the conflict shown below.

Specifications

• Datadog Lambda Layer version: not used; the datadog-lambda package from PyPI, 8.128.0 (also seen with 8.123.0)
• Python version: 3.14.7 (local; the target runtime is AWS Lambda python3.14)

Stacktrace

 $ pip install "datadog-lambda==8.128.0" "wrapt==2.5.0"
 ERROR: Cannot install datadog-lambda==8.128.0 and wrapt==2.5.0 because these package versions have conflicting dependencies.

 The conflict is caused by:
     The user requested wrapt==2.5.0
     datadog-lambda 8.128.0 depends on wrapt<2.0.0 and >=1.11.2
