Changelog

This page is part of the documentation for Orleans.Lattice 9.9.0 (release line 9.9), built 2026-10-04. It is also published as markdown, with every table and list, at CHANGELOG.md, and llms.txt lists every page.

All notable changes to the Orleans.Lattice package family are documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

This changelog covers the whole package family - every published Orleans.Lattice and Orleans.Lattice.* package, spanning the core library and its replication, storage, membership, auth, data, backup, caching, schema, scaling, dashboards, MCP, API/gRPC binding, and Explorer companions. Packages ship in lockstep on the major and minor digits; patch digits may advance per-package.

This is the v9.x changelog. Earlier release lines are archived: v8.x in CHANGELOG.old.v8.md, v7.x in CHANGELOG.old.v7.md, and v6.x and earlier in CHANGELOG.old.v6.md.
