The Polkadot-SDK has two release channels: stable and nightly. Production software is advised to only use stable. nightly is meant for tinkerers to try out the latest features. The detailed release process is described in RELEASE.md.

stable releases have a support duration of three months. In this period, the release will not have any breaking changes. It will receive bug fixes, security fixes, performance fixes and new non-breaking features on a two week cadence.

nightly releases are released every night from the master branch, potentially with breaking changes. They have pre-release version numbers in the format major.0.0-nightlyYYMMDD.

The security policy and procedures can be found in docs/contributor/SECURITY.md.

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.

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 here.
