Pull request overview
This PR migrates the Python SDK's license metadata to the modern PEP 639 format, replacing the deprecated dictionary-style license specification with a simple SPDX expression string. The changes ensure that both the base SDK wheels (MIT licensed) and the bundled CLI wheels (dual-licensed under MIT and the Copilot CLI license) properly declare their licenses according to current Python packaging standards.
Changes:
- Updated
pyproject.tomlto use PEP 639 format (license = "MIT"instead oflicense = {text = "MIT"}) and removed deprecated trove classifier - Modified wheel build script to generate dual-licensed metadata for bundled CLI wheels using SPDX expression
MIT AND LicenseRef-Copilot-CLI - Added logic to copy both SDK and CLI license files into bundled wheels with proper
license-filesmetadata
