CI stability improvements and targeted test updates accompanied these efforts, reducing manual troubleshooting and accelerating iteration cycles. Key deliverables included: - Windows Installer Proxy Support Enhancement: Respect HTTPS_PROXY and ALL_PROXY, with robust PowerShell proxy parsing and WebClient configuration; refactoring of proxy-related PowerShell functions for clarity and reliability. (Commits: 4d7760442db6771e271b7ad07b8b0a7cecd6dc81; bca0493655aed70ebfef99be9875f4074e375263) - Cargo-dist Proxy Handling Improvements: Robust proxy handling in the Download function, preferring HTTPS_PROXY/ALL_PROXY and falling back to credential-based URL parsing. (Commit: 39d7b46ea7c37f7ca49ec357b39618fee27bb674) - Localhost HTTP Testing Support (uv): Enables HTTP connections on localhost for testing while preserving HTTPS in other environments; improves error messages and adds tests to ensure localhost is accepted. (Commit: ae2dce6d252ffbfcb290a9a145695c3944254c40) - Prerelease Upgrade Enhancement in Python Version Manager: Allows upgrades of prerelease versions when minor versions match, with updated upgrade logic to correctly identify prerelease upgrades. (Commit: 46bf420eaec739a977f80cc9eba2bbe3a2d7520c) Overall, the month delivered tangible improvements in reliability and developer productivity by tightening proxy handling, expanding test coverage, and refining version management workflows.
