Release Notes

Release Notes • New feature (#1247, #1248) - .weaver.toml project configuration file for live-check. Covers all live-check CLI flags plus [[live_check.finding_filters]] for dropping findings by ID, minimum level, sample name, and signal type. CLI flags take precedence over config values. Use --config or auto-discovery from CWD. (#1256 by @jerbly) • Fix attribute catalog sorting for attributes with the same key when converting from v1 to v2 catalog. (#1359 by @michaelvanstraten) • Fix (#1323) - Live-check:treat observed int as compatible with expected double attribute type, avoiding false violations from OTLP serializers (e.g. JS) that emit int_value for integral numbers. (#1331 by @jerbly) • Fix CLI so it doesn't error out early when loading a resolved schema. (#1304 by @jsuereth) • 💥 BREAKING CHANGE 💥 Use schema_url to track registries consistently in lineage / provenance (#1298 by @jsuereth) • Publish and document missing JSON schemas. Add head_schema_url/baseline_schema_url to diff v2. (#1106 by @lmolkova) • Add --allow-git-credentials global flag to enable system credential helpers (e.g. osxkeychain, git-credential-manager) when cloning private registries. By default, git operations remain isolated for security. (#1306 by @jerbly) • MCP:Add browse_namespace tool and findings_only output mode for live_check. Add configurable namespace separator via --namespace-separator. (#1324 by @jerbly) • chore(deps):update all patch versions. (#1379 by @renovate[bot]) • Remove vendored openssl dependency.
