Testnet release 10.0

• Several backend db migrations that fix the state of the chain: bumping StorageVersion for pallets Balances, Scheduler, Staking
• Migrating all contracts from V8 to V9 version
• Update to Substrate v0.9.38, which is ink4 compatible
• Setting storage per one byte of contract storage: 4*10^{-5} AZERO per byte
• Increase total memory to 256MB, decrease call stack to 16 and enforce heap pages limit at cli.
• minor improvements to the finalization network

Mainnet hotfix release 8.4

Bumping pallet version for below pallets:

• Staking: V10
• Scheduler: V3
• History: V1
• TransactionPayment: V2

Testnet hotfix 9.1

Several backend db migrations that fix state of the chain:

• Bumping StorageVersion for pallets TransactionPayment, History, Scheduler, Multisig, Staking. Otherwise no functional changes for those pallets.
• Removing 6 nomination pools that are still on outdated V1 schema.
• Migrating V2 to V3 schema for all nomination pools.
• Migrating all contracts from V7 to V8 version

Testnet release 9.0

1. Update of pallet contracts that makes it compatible with Ink! 4.0.beta
2. Adjustments of the validator network:
   1. The legacy back-up network is removed, as it is not necessary anymore.
   2. The nodes establish now only one connection instead of two.
3. Update of AlephBFT to version 0.20, which introduces more efficient unit requests and various other improvements.
4. Validator suspension now has an additional effect of “chilling” the validator.

Mainnet release 8.3

• Fix for nomination pools unbonding issue:
  • add pending_rewards API call to Aleph Runtime

Testnet release 8.3

• Fix for nomination pools unbonding issue:
  • add pending_rewards API call to Aleph Runtime

Mainnet release 8.2

Release notes:

• a bugfix for a scenario in which finalization proofs (justifications) were not disseminated reliably enough, which caused some validators to think they are on the "main branch" while they were not,
• Stop producing blocks when finalization does not happen

Testnet release 8.2

Release notes:

• a bugfix for a scenario in which finalization proofs (justifications) were not disseminated reliably enough, which caused some validators to think they are on the "main branch" while they were not,
• Produce fewer blocks when finalization does not happen

Mainnet release 8.0

Release notes:

• Add a new mode to the elections subsystem that will allow permissionless elections on mainnet.
• Add automated removal of dead validators from the validators list for a given era. If a validator doesn’t produce blocks when they should and they meet the given threshold, they are removed from the validator list for the next era.
• Rewrite of network layer for the committee establishing consensus and ensuring better stability and performance.
• New layer for compatibility of consensus messages sent in alephbft enabling smoother runtime updates.
• There are improvements to the build process that result in a smaller and faster binary.
• The justifications are now created for all blocks that simplify the logic of several components.
• A new command to the binary for checking its version.
• Incorporated bug fix for the sync protocol.
• CCR basic support
• Fix for justification compatibility
• Try-runtime cli in the node (plus fixes for logging in the substrate)
• Pruning related changes
• Unit saving for crash recovery
• everybody wins - opens committee responsible for establishing consensus for outside validators
• pallet identity - enables human-readable aliases for accounts
• tweaks in substrate network - enable querying the same block multiple times
• compatibility for justifications
• substrate update 9.13 → 9.28
• AlephBFT 0.8.4 → 0.19.1
