Global Priority

‼️ HIGH: This is a high priority release and you must upgrade as as soon as possible.

The changes motivating this priority level are:

  • [P] #4594 ‼️ HIGH - Fix checking for the parachainhost runtime api
  • [S] ⏳ pending non-critical audit #9732 Low - Inner hashing of value in state trie (runtime versioning).
  • [P] ✅ trivial #4104 - Companion for substrate#9732

⚠️ The runtimes in this release contain 2 new host functions.
⚠️ It is critical that you update your client before the chain switches to the new runtimes. If you do not update your client before the new runtime is enacted, your node will stop handling parachains functionalities properly until you upgrade.
Also note that PR #9543 is a breaking change for the Prometheus metrics.

Rust compiler versions

This release was tested against the following versions of rustc. Other versions may work.

  • Rust Stable: rustc 1.57.0 (f1edd0429 2021-11-29)
  • Rust Nightly: rustc 1.58.0-nightly (46b8e7488 2021-11-07)

Migrations

This runtime contains a custom migration that fixes the locked deposit of a number of accounts who have voted for the Polkadot council in the past. See the list of affected accounts and more description #4655.

This runtime upgrade contains a custom migration that fixes the locked deposit participants of the historical Nicks pallet, which was only used temporarily in the Kusama runtime. See the list of affected accounts and more description #4656.
