Fix #4511: Widen opentelemetry version constraints to >=1.34.0,<2

Summary

The three opentelemetry dependencies (opentelemetry-api, opentelemetry-sdk, opentelemetry-exporter-otlp-proto-http) were pinned with ~=1.34.0, which resolves to >=1.34.0, <1.35.0. This prevented users from installing newer OpenTelemetry versions (e.g. >=1.38 or >=1.39.1) required by tools like Langfuse.

This PR widens the constraint to >=1.34.0,<2. crewAI only uses stable trace-related OpenTelemetry APIs (spans, tracer providers, baggage, context), and the only breaking change in recent releases (1.39.0) affects Log signal classes which crewAI does not use.

Adds a regression test suite (test_opentelemetry_version_compatibility.py) that verifies all OpenTelemetry imports used by crewAI resolve correctly and that the Telemetry singleton initializes successfully.

Review & Testing Checklist for Human

• Verify the OpenTelemetry trace APIs used in telemetry/telemetry.py, telemetry/utils.py, crew.py, and flow/flow.py remain stable across 1.34–1.39+ (the only known breaking change in 1.39.0 is Log-related, not trace-related)
• Confirm no other dependencies in the tree have conflicting OpenTelemetry version requirements that would cause resolution failures with the wider range
• Test plan: In a fresh environment, install crewai alongside opentelemetry-exporter-otlp-proto-http>=1.39.1 (the version from the issue report) and verify dependency resolution succeeds and basic crew execution works

Notes

• The added tests verify imports and minimum version at runtime but cannot truly validate that newer versions install correctly — that's a dependency resolution concern best verified manually or via the test plan above.
• The uv.lock diff only updates specifier strings; the actual resolved versions may remain at 1.34.x until a uv lock --upgrade is run.

PR #4519: fix: relax opentelemetry version pins to allow >=1.34.0,<2

• Repository: crewAIInc/crewAI
• Author: ManasVardhan
• State: open | merged: False

Description (problem / solution / changelog)

Summary

Relaxes the OpenTelemetry dependency version pins from ~=1.34.0 (which resolves to >=1.34.0,<1.35.0) to >=1.34.0,<2.

Problem

The current tight pins on opentelemetry-api, opentelemetry-sdk, and opentelemetry-exporter-otlp-proto-http prevent users from installing newer OpenTelemetry versions (e.g., 1.38.x, 1.39.x) alongside crewAI. This causes dependency resolution failures when users need newer OTel versions for other packages like Langfuse.

Example error:

Because crewai==1.9.3 depends on opentelemetry-exporter-otlp-proto-http>=1.34.0,<1.35.dev0
and your project depends on opentelemetry-exporter-otlp-proto-http>=1.38,<2.dev0,
your project's requirements are unsatisfiable.

Changes

• opentelemetry-api: ~=1.34.0 → >=1.34.0,<2
• opentelemetry-sdk: ~=1.34.0 → >=1.34.0,<2
• opentelemetry-exporter-otlp-proto-http: ~=1.34.0 → >=1.34.0,<2

The OpenTelemetry libraries follow semantic versioning, so any 1.x release should be backward compatible. The <2 upper bound protects against breaking changes in a future 2.0 release.

Fixes #4511

[!NOTE] Low Risk Dependency constraint-only change with no runtime logic modifications; risk is limited to potential incompatibilities if newer OpenTelemetry 1.x introduces unexpected behavior.

Overview Updates lib/crewai/pyproject.toml to relax the version constraints for opentelemetry-api, opentelemetry-sdk, and opentelemetry-exporter-otlp-proto-http from ~=1.34.0 to >=1.34.0,<2, improving compatibility with other packages that require newer OpenTelemetry 1.x versions.

PR #4533: fix: support opentelemetry-exporter-otlp-proto-http >=1.39.1

• Repository: crewAIInc/crewAI
• Author: hztBUAA
• State: open | merged: False
• Link: https://github.com/crewAIInc/crewAI/pull/4533

Description (problem / solution / changelog)

Summary

Fixes #4511

• Relaxed version constraints for opentelemetry-api, opentelemetry-sdk, and opentelemetry-exporter-otlp-proto-http from ~=1.34.0 (which restricts to >=1.34.0, <1.35) to >=1.34.0
• This allows users to install newer OpenTelemetry versions (e.g., 1.39.1) needed for proper telemetry export to Langfuse and other OTLP collectors
• The OpenTelemetry API is stable post-1.0 and crewAI uses only standard trace/span/exporter APIs with no version-specific features, so newer versions are fully compatible

Test Plan

• All 28 telemetry tests pass with the relaxed constraints
• uv lock resolves successfully
• Verified crewAI only uses stable OpenTelemetry APIs (trace, TracerProvider, BatchSpanProcessor, OTLPSpanExporter, Span, Status, StatusCode, Resource, SERVICE_NAME, SpanExportResult) that have not changed between 1.34 and 1.39.1

[!NOTE] Low Risk Dependency constraint loosening only; risk is limited to potential incompatibilities with newer OpenTelemetry versions at install/runtime.

Overview Relaxes version constraints for opentelemetry-api, opentelemetry-sdk, and opentelemetry-exporter-otlp-proto-http from ~=1.34.0 to >=1.34.0 so newer OpenTelemetry releases can be installed.

Updates uv.lock accordingly to reflect the broadened dependency range; no runtime code changes are included.

PR #4626: fix: relax opentelemetry dependency constraints to allow newer versions

• Repository: crewAIInc/crewAI
• Author: Anandesh-Sharma
• State: open | merged: False
• Link: https://github.com/crewAIInc/crewAI/pull/4626

Description (problem / solution / changelog)

Summary

• Relaxes opentelemetry dependency constraints from ~=1.34.0 (pinned to >=1.34.0,<1.35.0) to >=1.34.0,<2
• The tight pinning prevented users from using newer opentelemetry versions (e.g., 1.39.1) required by other tools like Langfuse
• Still protects against major version breaking changes with the <2 upper bound

Fixes #4511

Test plan

• Verify crewai installs successfully with opentelemetry 1.34.x
• Verify crewai installs successfully with opentelemetry 1.39.x
• Verify telemetry functionality works with both versions
• Verify no dependency conflicts with common companion packages (langfuse, etc.)
