🐛 Fixes
Correct v1.44.0 regression in query plan cache (PR #5028)
Correct a critical regression that was introduced in v1.44.0 which could lead to execution of an incorrect query plan. This issue only affects Routers that use distributed query plan caching, enabled via the supergraph.query_planning.cache.redis.urls configuration property.

Use entire schema when hashing an introspection query (Issue #5006)
Correct a different hashing bug which impacted introspection queries which was also introduced in v1.44.0. This other hashing bug failed to account for introspection queries, resulting in introspection results being misaligned to the current schema. This issue only affects Routers that use distributed query plan caching, enabled via the supergraph.query_planning.cache.redis.urls configuration property.
This release fixes the hashing mechanism by adding the schema string to hashed data if an introspection field is encountered. As a result, the entire schema is taken into account and the correct introspection result is returned.
Fix subgraph name mapping of Datadog exporter (PR #5012)
Previously in the router v1.45.0, subgraph name mapping didn't work correctly in the router's Datadog exporter. The exporter used the incorrect value apollo.subgraph.name for mapping attributes when it should have used the value subgraph.name. This issue has been fixed in this release.
