Upgrade priority:❗ HIGH ❗ Please upgrade your node as soon as possible due to changes: double the allocator limit (paritytech/substrate#9102), ✅ audited Add Control to Growth of the Staking Pallet (paritytech/substrate#8920), ✅ audited Decouple Staking and Election - Part 3: Signed Phase (paritytech/substrate#7910)

NOTE: This release introduces a new host function. As such, node operators should upgrade before the next runtime upgrade on their chain in order to continue being able to sync the chain.
