Migrating SDK versions

Migrate between Stratix SDK versions — breaking changes and replacement paths.

The SDK follows semver. Breaking changes are major-version bumps. Within a major, additions only.

v1.2 → v1.3

Additions:

  • client.judge_optimizations (GEPA) — new namespace

  • client.trace_evaluations.create(..., trace_set={...}) — new param

No breaking changes. Upgrade is drop-in.

v1.1 → v1.2

Additions:

  • client.spaces — new namespace

  • Improved retry semantics

No breaking changes.

Pinning

Production: pin exact version.

pip install layerlens --extra-index-url https://sdk.layerlens.ai/package==1.3.0

Development: pin the minor.
