Sneak Peek at Critter Stack 2026

This article provides a sneak peek at the upcoming Critter Stack 2026 coordinated major releases across all projects, built on JasperFx 2.0 foundation and targeting .NET 9 and .NET 10. Key themes include AOT-friendly improvements, faster cold-start performance, and shared deduplication infrastructure between Marten and Polecat. Detailed notes cover JasperFx 2.0 (AOT-compatible core, runtime Roslyn split, source generators), Weasel 9.0 (database layer with multiple providers), Marten 9.0 (no runtime code generation, closed-shape storage, best-perf defaults), and Polecat 4.0 (SQL Server/EF Core event sourcing, AOT-clean). The article includes links to documentation, releases, and migration guides, with a full writeup promised next week.
