OpenCode v1.15.1: Collapsible Thinking View and Pinned Sessions
SST
OpenCode v1.15.1 (May 16) adds collapsible thinking view with inline expansion, pinned sessions with quick-switch slots in the session picker, and fixes duplicate prompt history entries, file watching for repos where .git is a symlink, and multiline @-mention handling. The release follows v1.15.0 (Effect-based event system) and v1.14.51 (experimental background subagents) shipped May 15.
Why it matters
Pinned sessions with quick-switch slots improve multi-project workflows in the open-source coding agent. Background subagents from the preceding release bring OpenCode to parity with Claude Code's async session model.
Importance: 2/5
Incremental UI and reliability release; notable for background subagent parity with Claude Code
