Release Notes

linq2db/linq2db (linq2db)

v6.4.0: Release 6.4.0

Highlights of this release:

• New Sql.Window.* fluent API for window functions — ranking, offset, value, aggregate, statistical, regression, ordered-set and distribution functions, full ROWS/RANGE/GROUPS frames, named windows, FILTER, NULLS FIRST/LAST and Oracle KEEP, with compile-time safety. Existing Sql.Ext.*().Over() queries keep working unchanged — they run on the new pipeline internally (#​5468)
• Two new eager-loading strategies for LoadWith / ThenLoad and inline collection projections: KeyedQuery (buffers the parent query and loads children with WHERE key IN (…)) and CteUnion (collapses same-level collections into one UNION ALL CTE). Selectable per query or globally, with automatic fallback (#​5450)
• Named (keyed) query filters — HasQueryFilter(key, …) and selective IgnoreFilters(keys), mirroring the EF Core 10 API, including EF Core keyed-filter flow-through (#​5525)
• Fluent Upsert plus entity-based Insert(item, …) / Update(item, …) DML APIs (#​5482)
• linq2db.Analyzers — a new analyzer package shipped as a dependency of linq2db, with rule L2DB1001 and a code fix that migrates the legacy Sql.Ext window API to Sql.Window. Opt out with EnableLinqToDBAnalyzers (#​5703)
• Query cache is now bounded with idle eviction and a global cap, preventing unbounded growth in long-running apps with many distinct queries (#​5501)
• NULLS FIRST / NULLS LAST control on OrderBy / ThenBy with a DataOptions default, rendered natively or emulated across all providers (#​5561)
• Sql.NewGuid7() and Guid.CreateVersion7() mapping for UUIDv7 generation (#​5648)
• Automatic mapping of F# 'T option / 'T voption columns after .UseFSharp(), with none stored as NULL (#​5624)
• New opt-in PreferClientCalculation evaluates non-server-required projection expressions client-side, restoring v5 projection behavior (#​5604)
• DistinctBy emits native DISTINCT ON on PostgreSQL and DuckDB (#​5630)
• OptimizeForSequentialAccess became a per-context option, fixing query-cache collisions between sequential and non-sequential reader plans (#​5639)
• Raw-SQL materialization into records and constructor types now honors [Column] and [ValueConverter], binding by mapped column name rather than parameter name (#​5659)
• Provider auto-detection works under PublishSingleFile self-contained deployments (#​5489)
• Fixed corrupted SQL — swapped or duplicated aliases and column names — when one cached parameter-dependent query executed concurrently on multiple threads (#​5657)
• Two connection leaks fixed: provider version auto-detection left caller-supplied connections open (#​5691), as did the implicit EF Core ToLinqToDB() / ToLinqToDBTable() / GetTable<T>() helpers (#​5378)
• Other notable fixes: recursive CTE dropping columns on an object-typed projection member (#​5680), InvalidCastException on a local-collection LEFT JOIN feeding decimal arithmetic (#​5587), invalid SQL when subtracting two DateTime/DateTimeOffset columns (#​5581), [ExpressionMethod] running at materialization with IsColumn = false (#​5578), nested member-path mappings throwing in MERGE setters and discriminators (#​5545), InvalidCastException on Contains in a correlated subquery (#​5558), aggregates over a captured local collection turned into SQL subqueries (#​5557), and ORDER BY expressions lifted from a subquery producing invalid SQL (#​5556)

Provider-specific highlights:

• YDB — now a fully supported provider rather than experimental: schema API, CLI scaffolding, LINQPad driver and broad translation coverage (#​5564)
• PostgreSQL — v19 dialect with correct IGNORE NULLS / RESPECT NULLS window SQL (#​5644); v11 and v12 dialects, with unsupported window features rejected client-side with a clear exception (#​5687)
• SQL Server — new [GetSqlDecimal] attribute reads decimal columns whose precision exceeds the CLR decimal range instead of throwing (#​5605)
• Oracle / Informix — fixed cached queries producing wrong SQL on re-execution when a provider rewrite modified the cached statement in place (#​5723)
• EF Core — many-to-many (skip navigation) associations now translate to SQL (#​5588); the linq2db query cache no longer misses on every DbContext with pooled contexts or disabled service-provider caching (#​5695)
• Native AOT — fixed a crash triggered by lambda closures in queries (#​5552); EF Core on Mono / Android AOT — fixed a fatal crash reading model metadata (#​5546)
• LINQPad — the driver installs again on macOS and Linux from LINQPad's NuGet package manager, broken since 6.2.0 (#​5571)

linq2db.cli:

• New query, execute and schema commands, plus an MCP server for agent-driven database access (#​5678)

Full Changelog: linq2db/linq2db@v6.3.0...v6.4.0

v6.3.0: Release 6.3.0

Highlights of this release:

• Enum.HasFlag translation
• string.Concat / string.Join / TrimStart / TrimEnd translation improvements (with many translator-bug fixes uncovered along the way)
• AsCte builder overload for explicit CTE materialization configuration (PostgreSQL, ClickHouse, DuckDB, SQLite, DuckDB)
• AsQueryable(db, ...) overload with per-column parameterization control for VALUES clauses
• Improved Now / UtcNow translation with timezone awareness across providers; providers without TZ gracefully downgrade
• IgnoreConflicts option for MultipleRows mode BulkCopy on MySql / MariaDB / PostgreSQL / SQLite / DuckDB (thanks @​darko1979)
• Many other fixes: PostgreSQL array-parameter query cache misses, SqlQueryDependentParams issues, association discovery on interfaces, subquery null-aggregate SQL generation, UPDATE FROM regressions, ValueConverter null handling, CTE column removal, set-operator flattening, Sql.Row converters, predicate null-check optimization, FromSql caching, DropTable(throwExceptionIfNotExists: false) behavior, EXISTS over set queries

Provider-specific highlights:

• DuckDB — brand-new first-class provider (thanks @​stdray, #​5451), schema introspection, scaffolding via linq2db.cli, LINQPad support
• Oracle — COALESCE parameter type inference, DateTimeOffset.Now no longer corrupts TIMESTAMP WITH TIME ZONE writes, drop of global temp tables with data now works
• SQL Server 2025 — vector type fixes
• SQL Server + Firebird — date conversion fix for DbType="..." mappings
• ClickHouse — table-hint whitespace fix
• Access — non-EN locale compatibility re-fixes
• SAP HANA + DB2 + Firebird — proper SQL escaping in EXECUTE blocks for create/drop tables
• SAP HANA — DROP TABLE IF NOT EXISTS handled on SQL level
• EF.Core / SQL Server — UseSequence-defined fields now detected as identity (#​5439)
• F# support — compatibility with FSharp.Core 10.1.x; record mapping fixes for case-only-distinct member names

linq2db.cli:

• Per-RID tool packaging. linq2db.cli now ships as per-RID tool packages (win-x64/win-x86/win-arm64/linux-x64/linux-arm64/osx-arm64/osx-x64). dotnet tool install -g linq2db.cli auto-picks the variant for your SDK; add --arch x86 when you need 32-bit (Jet OLE DB; or to match a 32-bit ACE / SqlCe / SAP HANA driver).
• Breaking: --architecture scaffold option removed — bitness is now fixed at install time. Jet connection strings on a 64-bit process now fail fast with a clear x86-variant hint. See #​5539.
