chore(release): Release v1.2.0

[honeyhive-propolis]

Release v1.2.0

Version: 1.2.0

Changelog

[1.2.0] - 2026-06-04

Added

• Metric versions API: client.metric_versions
  • New client.metric_versions.list(metric_id), .create(metric_id, request), and .deploy(metric_id, version_name) methods (plus *_async variants) for managing a metric's immutable version history, backed by /v1/metrics/{metric_id}/versions. Each metric keeps a history of versions with one deployed at a time; pass deploy_immediately=True on create to atomically deploy the new version. Version request/response models are exported from honeyhive.models.

Fixed

• OTLP JSON exporter: serialize numeric fields as JSON strings
  • Integer span attributes (intValue) and uint64 timestamp fields
    (startTimeUnixNano, endTimeUnixNano, timeUnixNano) were emitted as
    raw JSON numbers. The protobuf JSON mapping spec requires these to be JSON
    strings; values above 2^53 could otherwise lose precision silently through
    float64 rounding. Now matches native opentelemetry-exporter-otlp-proto-http
    behavior.
• Decorator input capture: remove truncation of serialized list/dict values
  • List and dict span attributes are serialized to strings and
    previously were truncated to 1000 characters in length. The arbitrary limit
    of 1000 characters has been removed.
