Relax the wrapt upper bound from <2 to <3 so langfuse installs in environments that ship wrapt 2.x (e.g. GCP Cloud Composer). The previous ceiling was kept because the transitive wrapt pin via opentelemetry-instrumentation also capped <2. That upstream bound was relaxed to <3 in opentelemetry-python-contrib (open-telemetry/ opentelemetry-python-contrib#3903, released in opentelemetry-instrumentation 0.63b0), so the langfuse-side cap is now the only blocker. langfuse uses only wrapt.wrap_function_wrapper, whose API is unchanged in 2.x; verified langfuse imports and wraps cleanly under wrapt 2.1.2. Fixes langfuse#1561

Problem
Closes #1561.
langfusepinswrapt>=1.14,<2, which prevents installation in environments that ship wrapt 2.x — most notably GCP Cloud Composer, which shipswrapt==2.0.1. Users hit an unresolvable dependency conflict.As the issue notes, bumping this previously also required the transitive
wraptcap inopentelemetry-instrumentationto be lifted (open-telemetry/opentelemetry-python-contrib#3903).Why this is now unblocked
That upstream issue is resolved:
opentelemetry-instrumentationnow allowswrapt>=1.0.0,<3.0.0, shipped inopentelemetry-instrumentation0.63b0 (released 2026-05-19). langfuse's existing otel bounds already permit that release, so the langfuse-side<2ceiling is the only remaining blocker.Change
pyproject.toml:wrapt>=1.14,<2→wrapt>=1.14,<3uv.lockCompatibility
langfuse's only use of wrapt is
wrapt.wrap_function_wrapper(langfuse/openai.py), whose API is unchanged across 1.x → 2.x.Verification
uv lockresolves cleanly.wrapt 2.1.2installs with langfuse's production dependencies (--no-dev) — the GCP Cloud Composer scenario.wrap_function_wrapperwrapping work underwrapt 2.1.2.
