OpenCode shipped v1.19.1-v1.19.3 (Oct 15-16). v1.19.1 discontinues session sharing outright — existing share links, sharing commands, and import from share URLs no longer work. v1.19.2 ensures 1.x installs only see 1.x update checks, keeping the OpenCode 2.0 upgrade opt-in via /update or opencode upgrade --major (flagged in v1.19.0). v1.19.3 makes model reasoning options configurable to produce reasoning variants.

Why it matters

Disabling session sharing is a user-visible removal, and the versioning split signals how the 2.0 rollout will be staggered.
