The Polkadot SDK is released every three months as a `stableYYMMDD` release. They are supported for
one year with patches. See the next upcoming versions in the [Release
Registry](https://github.com/paritytech/release-registry/).
You can use [`psvm`](https://github.com/paritytech/psvm) to update all dependencies to a specific
version without needing to manually select the correct version for each crate.
## 🛠️ Tooling
[Polkadot SDK Version Manager](https://github.com/paritytech/psvm):
A simple tool to manage and update the Polkadot SDK dependencies in any Cargo.toml file.
It will automatically update the Polkadot SDK dependencies to their correct crates.io version.

Development in this repo usually goes hand in hand with the `fellowship` organization. In short,
this repository provides all the SDK pieces needed to build both Polkadot and its parachains. But,
the actual Polkadot runtime lives in the `fellowship/runtimes` repository. Read more about the
fellowship, this separation, the RFC process
[here](https://polkadot-fellows.github.io/dashboard/).
This repository is the amalgamation of 3 separate repositories that used to make up Polkadot SDK,
namely Substrate, Polkadot and Cumulus. Read more about the merge and its history
