v3.1.4

Hotfix: #1757

v3.1.3

Emergency deploy of #1754 + #1755 + #1756

v3.1.2

Hotfix

#1732

v3.1.0

Yuma Consensus v3 (available for all subnets)

• Per-bond EMA scaling: individual & sparse-mode bonds now adapt via exponential moving
  averages for smoother rewards
• Refactored α-parameters (including new sigmoid-steepness tuning) for fine-grained consensus
  control
• Monte Carlo scenario tests & map_consensus.py integration tests validate retention guarantees
  under adversarial conditions
• On-chain toggle event & ABI support to enable/disable Yuma3 per subnet for easy rollbacks
• #1593

Notes for Subnet Owners

• Yuma 3 should be beneficial and safe to use in model verification subnets (specifically subnets which guarantee that a change in miner performance happens with a knowledge commitment), provided the bond reset flag is used correctly.
• It will distribute dividends to the validators more fairly than Yuma 2 did and Liquid Alpha 2.0 allows the subnet owners to disincentivize weight copying.

Generic Crowdloan Pallet (live for public testing)

• Launch generic crowdloans via a simple balance-transfer + arbitrary extrinsic
  wrapper—supports create, contribute, withdraw, refund & finalize flows
• Enforce a 500-contributor cap to prevent unbounded loops and track counts for benchmarking
• Hardened withdraw logic: only the original contributor can withdraw, and creator’s initial
  deposit is locked until dissolution
• #1503

Notes

The MEV-resistant staking PRs have been pulled back for now while we address some issues pointed out by the community but should be in an upcoming release
