v1.19.3 v1.19.2
anomalyco/opencodeOct 16, 2026 → Oct 16, 20260 days between releases
What's New
v1.19.2 is actually older than v1.19.3, so this delta is a downgrade that removes reasoning options.
Breaking Changes
- Downgrading to v1.19.2 removes the model reasoning options and reasoning-variant generation introduced in v1.19.3, reverting to catalog variants.
- Configs that rely on reasoning variants or preserved variant overrides from v1.19.3 will not behave the same on v1.19.2.
- v1.19.2's notes emphasize 1.x lock and explicit `opencode upgrade --major` for v2, which are not mentioned in v1.19.3's notes and may change upgrade behavior.
Bug Fixes
- v1.19.2 documents yarn upgrade fixes and skipping 1.x updates for Homebrew Core installs, but these are not a confirmed delta from v1.19.3.
Upgrade Notes
Do not treat v1.19.2 as newer: it was published earlier and has a lower semver than v1.19.3. If you downgrade, back up any reasoning-option configs and expect catalog variants to return; otherwise stay on v1.19.3 or later.
