This page lists all designated compatibility checkpoint releases for the Fluid Framework. See the Cross-Client Compatibility Policy for how checkpoints define the compatibility window.
Checkpoints are designated on a cadence of no less than 6 months. Any two clients whose checkpoint releases are within 18 months of each other (spanning Checkpoint N through Checkpoint N-3) are guaranteed to be cross-client compatible.
The Version Range column lists the semver range of Fluid Framework releases that fall under the checkpoint; every release in the range shares the same cross-client compatibility guarantees as the opening release (the range's lower bound).
The Compatible Semantic Versions column lists the full semver range a client running a checkpoint version is guaranteed to be compatible with. Upper bounds for in-window checkpoints are estimated and depend on when future checkpoints are designated.

Notes:
CC-1,CC-2, andCC-3were designated retroactively based on existing Fluid Framework releases, which is why the cadence between them is irregular. Starting withCC-4, checkpoints follow the standard cadence.- Dates and version ranges for future checkpoints are estimates and are subject to change. Exact release versions and dates will be added as each checkpoint is designated.
