v4.3.3 — versioned model picker, Opus pinned as default
v4.3.3 — 2026-07-27
🧬 The model picker shows the version now — and picks Opus for you. The list of models is read straight from the binary (it always was), but it used to label each one without its version — "Opus (1M context)", "Sonnet" — so you couldn't tell Opus 4.8 from Opus 5. Every model now shows its version ("Opus 5 with 1M context", "Sonnet 5", "Haiku 4.5"), in both the composer and Settings. The vague "Default" entry — which was just Opus listed a second time, with no version — is gone, and a fresh install defaults to the concrete Opus tier and stays there. A stale hardcoded "Opus 4.8" label that lingered on the pill is gone too.
Maintenance: protocol baseline refreshed to the latest claude 2.1.220 / SDK 0.3.220 (no protocol changes). Verified Compatible on IC-251, IC-252, IU-253, IU-261 and IU-262.
