Note

Medium Risk
Adds network egress allowlist semantics for pooled browsers and changes 1Password fill outcome guidance, which can affect automation retry logic; changes are mostly additive typed fields and documentation.

Overview
Release 0.123.0 updates the Go SDK to match new Kernel API surface and docs.

GPU browser sessions can request video_memory (2GiB or 4GiB) on create; responses expose the same field when gpu is true, along with 12GiB as a new BrowserMemory value for the larger VRAM tier.

Browser telemetry SSE streaming adds a type query parameter to limit delivered event types, with documented id-only frames so Last-Event-ID advances past filtered or undeliverable events.

Browser pools now document network.allowed_hosts egress allowlists on pools and leased browsers (reset/replace behavior on release and pool updates), replacing earlier “not supported on pools” wording.

Vault / 1Password fill result and credential-request docs are tightened: fill_unknown may include error_code (e.g. autosubmitFailed), clients should inspect the page after uncertain fills, and blanket “do not retry fills” guidance is relaxed relative to uncertain requests.
