Code Guardrail v0.8.0 - Copilot SDK Intelligence

Code Guardrail v0.8.0 — Release Notes

Release Date: March 7, 2026

What's New

GitHub Copilot SDK Intelligence Layer (Major)

The core analysis engine has been upgraded to use the modern GitHub Copilot SDK API (@github/copilot-sdk) with the sendAndWait() pattern, replacing the legacy event-based approach.

Before (v0.7.0):

• Used deprecated session.on('assistant.message') event-based pattern
• Manual timeout/promise management prone to hangs
• Outdated gpt-4 model default

After (v0.8.0):

• Modern session.sendAndWait({ prompt }, timeout) for reliable responses
• Streaming support via SessionEvent typed callbacks for large file analysis
• Default model upgraded to gpt-4.1 for better analysis quality
• Proper error handling with descriptive messages (ENOENT, ECONNREFUSED)
• systemMessage.content format aligned with SDK specification

New Extension Logo

Fresh brand identity with a professional shield + guardrail + code motif icon.

Streaming Analysis Support

New analyzeWithStreaming() method in the Copilot provider enables real-time progress feedback during large file analysis.
