Copilot CLI 1.0.26: Plugin Env Vars & Windows LSP Fix
Copilot CLI 1.0.26 adds plugin environment variables, improves keyboard navigation, and fixes Windows LSP initialization, enterprise login, and plugin installation bugs.
TL;DR
- Plugin hooks now receive PLUGIN_ROOT, COPILOT_PLUGIN_ROOT, and CLAUDE_PLUGIN_ROOT env vars
- Session scope selector is keyboard-navigable with arrow keys
- Fixed Windows LSP initialization, enterprise login, and plugin installation bugs
New
- Plugin environment variables — Plugin hooks now receive PLUGIN_ROOT, COPILOT_PLUGIN_ROOT, and CLAUDE_PLUGIN_ROOT env vars pointing to the plugin's installation directory.
Improved
- Session scope selector — Now more prominent and keyboard-navigable using left/right arrow keys in sync prompt.
- Instruction file consolidation — Files with specific applyTo patterns are consolidated into a table instead of inlining full content, reducing context window usage.
Fixed
- ACP server now binds to localhost only, preventing unintended network exposure.
- Installing a plugin named 'git' from a marketplace no longer fails due to incorrect URL parsing.
- Enterprise login now accepts hostnames without a URL scheme (e.g. 'github.example.com').
- LSP language servers correctly initialize on Windows using proper file URI paths.
- Relative paths in file edit operations now resolve against the session working directory.
Update with: npm install -g @github/copilot-cli@1.0.26-0
