0.25.1 - 2026-07-28

Release Notes

• Fix v2 attribute resolution so a ref inside an included group (ref_group) merges field-by-field instead of replacing the whole attribute. (#1634 by @lmolkova)
• Make schema_url mandatory for manifest dependencies (#1651 by @jerbly)
• Fix imported groups keeping the losing version's definition and provenance (#1650 by @jerbly)
• Fix imported attributes losing their origin registry provenance (#1649 by @jerbly)
• Fix live-check admin server (and /stop) shutting down 60s after startup (#1645 by @NimrodAvni78)
• Fix signals imported from a dependency losing their per-signal attribute data. When several signals reference the same attribute with different requirement_level or role, each imported signal was re-pointed at whichever variant of the attribute was registered first. E.g. silently rewriting requirement levels or dropping role: identifying from imported entities. Each signal now references the attribute variant it actually declares. Per-name conflict resolution still applies to root-attribute provenance. (#1635 by @jerbly)
