Release Notes

Note: 0.22.0 release was skipped due to release CI/CD issues.

• Fix: Update release workflow for pnpm migration (use pnpm lockfile instead of npm lockfile). (#​1289 by @​jerbly)
• Add support for git references in the registry url (#​182 by @​sebasnabas)
• New feature (#​1153) - Live-check now has a /health endpoint that can be used in long-running scenarios to confirm readiness and liveness of the live-check server. (#​1193 by @​jerbly)
• New feature (#​1100) - Set --output=http to have live-check send its report as the response to /stop. (#​1193 by @​jerbly)
• Unified output handling across all registry subcommands. Builtin output formats (json, yaml, jsonl) are now available in registry stats, registry diff, and registry resolve. registry stats also supports --templates for custom text output templates. (#​1200 by @​jerbly)
• New feature (#​1152) - Live-check with --emit-otlp-logs will now include the attributes from the resource in the emitted log record, this helps to identify the source of the finding in a multi-source environment. (#​1206 by @​jerbly)
• New Experimental feature: weaver registry infer command that listens for OTLP telemetry and infers a semantic convention registry file from the received data. Supports spans, metrics, events, and resource attributes. Includes configurable gRPC address/port, admin server for graceful shutdown, and inactivity timeout. (#​1138 by @​ArthurSens)
• Fix: Include unit in inferred schema even if empty to prevent live-check failures. (#​1284 by @​ArthurSens)
• Use schema_url in registry manifest, dependencies, and resolved schema instead of registry_url. Parse registry name and version
  from it. (#​1202 by @​lmolkova)
• Default to manifest.yaml for registry manifest file, deprecate registry_manifest.yaml and add warning when it's used. (#​1202 by @​lmolkova)
• 💥 BREAKING CHANGE 💥 (Fixes #​760) - Auto-escaping is now off by default (none) for all templates, regardless of file extension. To opt in, set auto_escape: html or auto_escape: json per template in weaver.yaml. Within a template, {% autoescape false %} blocks can selectively disable escaping for sections. Use |tojson for explicit JSON/YAML value escaping where needed. (#​1239 by @​jerbly)
• 💥 BREAKING CHANGE 💥 Replace version: "2" with file_format: definition/2 for v2 definition schema (#​1154 by @​lmolkova)
• Add JSON schema for resolved registry v2 (#​1261 by @​lmolkova)
• Add weaver registry package command to generate manifest and write resolved schema. (#​1254 by @​lmolkova)
• Fix: weaver registry package command not producing output due to warnings. (#​1271 by @​lmolkova)
• Update JSON Schema v2 to include file_format (#​1262 by @​lmolkova)
• Add JSON schema for PolicyFinding, make context field optional. (#​1270 by @​lmolkova)
• Deprecate weaver registry resolve command, please use weaver registry generate or package instead (#​1255 by @​lmolkova)
• Support imports for all signal types and public attribute groups in v2 registry. (#​1267 by @​jsuereth)
• Support refinements in v2 syntax: metric names, notes, etc. are now copied from the refined group. (#​1250 by @​jsuereth)
• Fix stability/ordering issues in v2 publishing; attributes are now sorted and deduplicated consistently. (#​1282 by @​jsuereth)
• Fix resolution for dependencies: both v1 and v2 resolution now returns the correct attribute from the right registry when using dependencies. (#​1280 by @​lmolkova)
• JQ helper v2 for spans: fixes and improvements. (#​1251 by @​lmolkova)
• Fix 404 on template-type attributes in the weaver serve API. (#​1240 by @​jerbly)
• New Experimental feature: weaver serve UI migrated to React. (#​1147 by @​nicolastakashi)
