Kusama CC-2 v0.6.13

Stability release focusing on a significant bug fix (paritytech/substrate#4071)

Kusama CC-2 v0.6.12

Bug fix release relating to critical performance issues.

• Fix ancient chain sync.
• Avoid periodic block announcement.
• Additional logging for tx queue.
• Additional telemetry data collection.

Kusama CC-2 v0.6.11

Service release for the Kusama network.

Substrate update bringing three main optimisations:

• Transaction queue runs in its own thread, avoiding blocking block-processing, potentially causing choppy sync.
• Network gossip optimised to keep consensus traffic to/from non-validator nodes to near zero and significantly lower traffic between validators. This should also help reduce CPU footprint.
• Consensus messages are now sent and processed in batches, optimising CPU overhead.

Kusama CC-2 v0.6.10

Significant feature release.

Includes:

• Ahead-of-Time (AOT) Wasm compiler for runtimes! This speeds up block/transaction execution dramatically. It is still experimental; to enable it use --wasm-execution Compiled

Includes runtime 1017, which contains:

• New Grandpa validators as known-keys, with storage migration.
• Fixes for treasury/NPoS rewards.
• New Balances::transfer_keep_alive extrinsic type for transferring from an account without destroying it.

Includes bump to Substrate master containing:

• Import without state verification, allowing validators to safely use normal pruning.
• Bans on invalid incoming transactions and reduce reputation of the peers that send them. This will reduce CPU workload and lower connectivity of nodes that run older, buggy and obsolete versions.

Kusama CC-2 v0.6.9

Service release for Kusama.

• Updates Substrate to a version that reverts header-only sync for consensus.

Kusama CC-2 v0.6.8

Service release for Kusama network.

Includes:

• additional diagnostics for networking;
• potential fix for block import stuttering;
• transaction dropping for im-online.

Kusama CC-2 v0.6.7

Service release for Kusama network. Includes:

• Governance-enabled runtime 1013.
• Update to Substrate master including significant fix for sync/consensus.

Kusama CC-2 v0.6.6

Service release.

• Provides native runtime version 1012.
• Bumps Substrate to latest master which includes a potential fix for storage cache.

Kusama CC-2 v0.6.5

A small service release for the Kusama network which brings in several improvements from Substrate. Included:

• Introduced --sentry flag for validator sentries.
• An RPC to allow transaction information to be queried including fees and weight.
• Phragmen elections module now states the amounts of votes backing each councillor.
• An improvement to allow council vote unlocking even if all funds are locked.
• Improvements to the staking module to ensure that inactive validators are deselected.
• A minor fix for the transaction queue.
• A fix for Grandpa.

Kusama CC-2 v0.6.4

Minor service update to enable support for nicknames. Substrate version also bumped.
