v1.1.49: Fix Session Freeze, Add Haskell Formatting
Release Date: February 3, 2026
One-Line Summary
This update fixes multiple critical issues including session freeze and file status calculation errors, adds Haskell code formatting support, and significantly improves desktop interaction experience.
Bug Fix: Session Freeze Issue
Previous Issue
When a session encountered an error, the status would get stuck in error state, preventing new sessions from starting.
Current Status
Fixed session state management. New sessions can start normally after errors. OpenCode no longer freezes.
New Feature: Haskell Code Formatting
What was updated?
Added Ormolu code formatter support for formatting Haskell code.
What is Ormolu?
Ormolu is a Haskell code formatting tool, similar to Prettier for JavaScript, that can automatically unify code style.
How to use?
When a project contains Haskell code, OpenCode will automatically use Ormolu for formatting.
New Feature: Custom mDNS Domain
What was updated?
Added --mdns-domain flag to customize mDNS hostname.
What's it for?
When accessing via LAN, you can customize a more friendly domain name.
How to use?
opencode --mdns-domain mydevice.localImprovement: Desktop Interaction Experience
Project Search
Now you can search projects on desktop to quickly find the project you want to open.
Session Navigation
Added keyboard shortcuts to switch between unread sessions.
Tab Close Shortcut
Added shortcut for closing tabs.
Responsive Design
Added breakpoints for optimized large screen layout.
Bug Fixes
File Status Calculation
Added and deleted files now correctly calculate status.
OpenAI Session Title Generation
Fixed session title generation issue when using OpenAI models.
Task Status Display
Fixed task status not showing current tool status.
Copilot Provider
Fixed Copilot provider system message content conversion issue.
Agent Variable Scope
Fixed agent variant not properly scoped to model.
@ Mention Hidden Files
Fixed issue where folders and files starting with . couldn't be mentioned with @.
Windows PTY Encoding
Added UTF-8 encoding defaults for Windows PTY.
