v1.1.57: Major Desktop Optimization
Release Date: February 11, 2026
One-Sentence Summary
This update significantly optimizes desktop app experience, fixes terminal copy/paste, Windows adaptation, Wayland support issues, and improves context compression reliability.
New Feature: WSL Backend Mode
What's Updated?
Desktop OpenCode now supports WSL backend mode, allowing OpenCode to run through WSL on Windows for better compatibility.
What is WSL Backend Mode?
If you use WSL (Windows Subsystem for Linux) on Windows, you can have desktop OpenCode run in the WSL environment instead of directly on Windows.
What are the Benefits?
- Better Linux toolchain compatibility
- Filesystem behavior consistent with Linux
- Avoid some Windows-specific issues
Improvement: More Reliable Context Compression
Previous Issue
In long conversations, OpenCode automatically compresses context to save tokens. But sometimes compression wasn't reliable enough, potentially causing information loss.
Current Status
- Added reserved token buffer, leaving enough space for input window compression
- Added more context overflow handling scenarios
- Removed over-correction situations
Improvement: TUI Sidebar Defaults to Auto
Change
TUI (terminal interface) session sidebar now defaults to "auto" mode, automatically showing or hiding based on terminal width.
Bug Fix: Multiple Desktop Improvements
Terminal Copy/Paste
Previously desktop app terminal copy/paste had issues, now fixed.
Windows App Adaptation
- Improved Windows app resolution detection
- Optimized UI loading state
- Fixed copy path button style
Wayland Support
Desktop app now reads Wayland preference from config, better supporting Linux Wayland display server.
