Note

Medium Risk
Changes retry backoff behavior by always honoring Retry-After/Retry-After-Ms (clamped to non-negative), which can materially affect request timing and throughput under error conditions. Other updates are CI gating and routine release/version bumps.

Overview
Releases v0.42.2. Updates version metadata (internal/version.go, .release-please-manifest.json), documentation (README.md), and CHANGELOG.md.

CI artifact uploads are now skipped on internal stl/* branches. The build job only fetches an OIDC token and uploads the tarball when the ref does not start with refs/heads/stl/.

Retry behavior change: internal/requestconfig.retryDelay now always uses the server-provided retry delay (via Retry-After headers) and clamps negative values to 0, instead of ignoring large values.

Test fixtures update placeholder upload content strings from "some file contents" to "Example data".

Removed upper bound allows unbounded retry delay

Medium Severity

The retryDelay function previously capped server-provided Retry-After values at under one minute, falling through to exponential backoff (max 8 seconds) for larger values. The new code removes that upper bound entirely, meaning a server sending a large Retry-After value (e.g., hours or days) will cause the client to block for that entire duration. While ctx.Done() in the select provides protection when a context deadline is set, callers without a deadline could experience unbounded blocking.
