OpenCode 2.3.0 is out, and the release notes are real this time, not a changelog stub. The headline changes are about how the session feels when several things are happening at once.
Subagents now run in the background by default. They return immediately, keep working, and report back to the parent session when they go idle, so you can keep going while more than one of them is busy. Transcripts are quieter by default too: the TUI summarizes each run of tool calls and thoughts into one collapsible activity row, and you can turn verbosity back up in settings if you want every step. In the desktop app, Jump to message, also bound to Cmd+Alt+G (Ctrl+Alt+G on Windows and Linux), lets you search prompts in the current session and jump straight to one.
There’s more under the hood if you want it: experimental MCP events and a flag for moving a shell command to the background when it hits its timeout, shell commands that survive server handoffs, LM Studio decision-model support, providers that can present a client certificate for mutual TLS, and some memory and truncation fixes. Read the notes if any of those flags matter to you.
Review before you install: read the release notes yourself, back up your config, and try new versions somewhere you can afford to break first.
My take
Background subagents and a calmer transcript are the right defaults. The jump-to-prompt shortcut in the desktop app is the little quality-of-life change I’ll actually use. As always, read the notes before you upgrade, especially if you already tuned verbosity or have a workflow that assumed subagents blocked the parent session.
God Bless, and Happy hacking!
