Note

Medium Risk
Proxy type and union field renames are breaking for Go consumers; browser name/tags are additive API surface with straightforward SDK mapping.

Overview
Release 0.63.0 bumps version metadata (manifest, PackageVersion, README install pin, changelog) and refreshes the OpenAPI spec reference in .stats.yml.

Browser sessions gain optional name and tags (map[string]string) on create via BrowserNewParams, echoed on get/list/new/update responses (including pool acquire and invocation browser listings). BrowserListParams now supports tags query filtering (ANDed key-value pairs) and documents query as including session name.

Proxy API types are renamed for clearer oneOf variants: config structs drop the *ProxyConfig suffix (e.g. ProxyNewResponseConfigDatacenter), union cast helpers become AsDatacenter(), AsIsp(), etc., and create params use OfDatacenter, OfResidential, OfCustom, and similar instead of the previous long names—callers must update field names and cast methods.

Tests and api.md are updated for the new browser and proxy shapes.

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.
