1. Link to an existing issue:

• Closes: Support OpenTelemetry 1.39 #4898

Description

The <1.39.0 upper bound on opentelemetry-api and opentelemetry-sdk was added due to agent_engines exporter constraints in google-cloud-aiplatform. The upstream package (latest v1.141.0) now specifies opentelemetry-sdk<2 for both the agent-engines and reasoningengine extras, so this constraint is no longer needed.

Changes:

• opentelemetry-api>=1.36.0, <1.39.0 → opentelemetry-api>=1.36.0, <2.0.0
• opentelemetry-sdk>=1.36.0, <1.39.0 → opentelemetry-sdk>=1.36.0, <2.0.0

Testing Plan

Unit Tests:

• No new unit tests needed — this is a dependency version constraint change only.
• All unit tests pass locally.

5010 passed, 1943 warnings, 6 subtests passed in 78.64s

Manual End-to-End (E2E) Tests:

N/A — no code changes, only dependency metadata.

Checklist

• I have read the CONTRIBUTING.md document.
• I have performed a self-review of my own code.
• I have commented my code, particularly in hard-to-understand areas.
• New and existing unit tests pass locally with my changes.
• Any dependent changes have been merged and published in downstream modules.

Additional context

Verified on PyPI that google-cloud-aiplatform==1.141.0 specifies opentelemetry-sdk<2 for agent-engines extra, confirming the upstream constraint has been relaxed.

hi, what's the latest here?

[partha-lgtm]

google-adk 1.15+ transitively pulls opentelemetry-exporter-gcp-logging (via google-cloud-aiplatform[agent-engines]), and THAT package also caps OTel <1.39.0. Is there any work on that side @rohityan

[brucearctor]

@partha-lgtm It looks like that concern has actually already been addressed upstream. The opentelemetry-exporter-gcp-logging package was updated in GoogleCloudPlatform/opentelemetry-operations-python#461 — versions 1.10.0a0+ now require opentelemetry-sdk >= 1.39.0 (flipping the old < 1.39.0 cap). You can see the current constraint in setup.cfg.

So once this PR's OTel relaxation to < 2.0.0 lands, pip will resolve to opentelemetry-exporter-gcp-logging >= 1.10.0a0 alongside OTel 1.39+. No additional changes needed on the transitive side, unless I am missing something?
