Note

Medium Risk
Proxy union renames are a breaking Go API change for existing integrations; browser name fields are additive but uniqueness rules apply at create time.

Overview
Release 0.63.0 bumps package/docs version metadata and refreshes the pinned OpenAPI spec hash.

Browser sessions gain an optional name on create (BrowserNewParams) and a name field on session responses (including pool acquire and related types). List browsers query search is documented to match name as well as existing identifiers.

Proxy config unions are renamed for clarity: variant structs drop the redundant ProxyConfig suffix (e.g. ProxyNewParamsConfigDatacenter), request union fields use OfDatacenter, OfIsp, etc., and response helpers use AsDatacenter(), AsResidential(), and similar instead of long AsProxy*Config*ProxyConfig names. Tests follow the new OfDatacenter shape.

Callers upgrading from 0.62.0 must update any code that referenced the old proxy type or union field/method names.

Created a monitoring plan for this PR.

What this PR does: Publishes the kernel-go-sdk v0.62.1 Go module release — a version-metadata-only patch with no behavioral code changes.

Intended effect:

• SDK PackageVersion string: baseline 0.62.0; confirmed if 0.62.1 is the version string in SDK user-agent headers after consumers upgrade, with no new errors introduced.
• Railway HTTP error rate: baseline 0.001–0.09% (0–116 errors/hr at 68K–150K req/hr today); confirmed if rate stays within this range after any consumer upgrades to this version.

Risks:

• No logic changes — negligible blast radius: This PR only updates version metadata files (internal/version.go, README, CHANGELOG, release manifest). No new code paths, no DB migrations, no endpoint changes. Alert if Railway HTTP error rate exceeds 0.5% for 2+ consecutive hours post-consumer-upgrade.
• Auto-upgrade consumers: If any downstream service pins to a floating latest-style reference, they would pick up this bump automatically. The expected effect is no change in behavior; alert if any new error pattern emerges after an upgrade event.
