Release v15.34.12

Fixed

• Read-model properties typed as a collection of concepts (e.g. IReadOnlyList<MyConcept> where MyConcept : ConceptAs<string>) are no longer silently persisted as an empty/missing array. Such a property now stores the unwrapped underlying values, the same way a scalar concept already did. A scalar concept and a collection of records in the same read model were always persisted correctly; only collections of bare concepts were affected.

Security

• Pin the native SQLite library (SQLitePCLRaw.lib.e_sqlite3) to the patched 3.50.3 build, addressing a known high-severity vulnerability (GHSA-2m69-gcr7-jv3q) bundled in the 2.1.11 version pulled in transitively by EF Core Sqlite.
