v1.19.4

Core

v1.19.3

Core

Improvements

• Configure model reasoning options to generate reasoning variants, replacing catalog variants while preserving your configured variant overrides.

v1.19.2

Core

Bugfixes

• OpenCode 1 now stays on the 1.x release line: update checks use only the npm opencode-ai latest version, so 1.x installs are never offered a 2.x build as a regular update.
• Upgrading to OpenCode 2 remains a separate, explicit choice through the 2.0 offer in /update or opencode upgrade --major.
• Fix upgrades for installs managed by yarn.
• Skip 1.x updates for Homebrew Core installs, which now track OpenCode 2, and check tap and Chocolatey availability before offering an update.
• The install script refuses to install 2.x versions.

v1.19.1

Core

Bugfixes

• Session sharing has been discontinued. Existing share links and session-sharing commands are no longer available, and importing sessions from share URLs is unsupported.

v1.19.0

Core

Improvements

• Run opencode upgrade --major to upgrade to OpenCode 2.

Bugfixes

• Allow the OpenAI ultrafast service tier.
• Validate PTY connection origins and tickets before checking whether a PTY exists.

TUI

Improvements

• Use /update to install OpenCode updates or upgrade to OpenCode 2; updates are no longer installed automatically.
