Previously, latest was selected using Python's built-in max() on raw version strings, which performs lexicographic comparison (e.g. "9.0.0" > "10.0.0") and did not exclude pre-release versions. - Parse all version strings once via semver.Version.parse, skipping any malformed values, to avoid redundant parsing and ValueError on invalid versions in the fallback path - Filter out pre-release versions (e.g. 1.0.0-alpha.1) when selecting the latest dist-tag; fall back to all valid semver versions if no stable versions exist - Add semver>=3.0.0 as a declared runtime dependency in pyproject.toml - Fix extract_package_info() regex to match full semver strings including pre-release and build-metadata suffixes; make base_name non-greedy ([^/]+?) to avoid ambiguity on hyphenated package names like my-pkg-1.0.0-rc.1.tgz, where a greedy match would consume into the version and cause extract_package_info() to return (None, None) Assisted By: Bob
- Fix import sorting (ruff I001) and line length in models.py - Add upper bound to semver dependency (semver>=3.0.0,<4) - Add functional tests for semver dist-tags resolution: - latest uses semver ordering (10.0.0 > 9.0.0) - pre-release versions excluded from latest - fallback to pre-release when no stable versions exist Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
