Release Candidate v0.15.4

Instructions for Node Maintainers

This is the first release that includes the database version upgrade introduced in #494. When you run this version with an existing datadir, you may be asked to upgrade your database version in CLI. To proceed, type y or yes and hit enter. Alternatively, you can run this version with a --yes flag to skip the interactive question.

This database upgrade is a one-way path, which means after updating your datadir to the new version, you won't be able to go back to an earlier version.

Testnet 11 Only v0.15.4

WARNING: INTENDED FOR USE IN TESTNET 11 ONLY

This is a special release with code not in the mainline yet. It is intended to hardfork the testnet-11 environment and should only be used by Testnet-11 node maintainers.

The TN11 HF includes:

• Enabling KIP10
• Switching KIP9 to use the Beta version in consensus
• Enabling Payloads for transactions

In addition, this includes all the optimizations that we have been working on which will allow us to determine a minimum recommended hardware spec for 10bps in mainnet.

Release v0.15.2

Released mainly for Integrators using GetVirtualChainFromBlock

NOTE: If you do not use GetVirtualChainFromBlock in your integration, you do not need to update to this version.

This release updates the GetVirtualChainFromBlock so that it operates in batches. This solves an issue where the call to GetVirtualChainFromBlock would previously take a long time to complete if the client has to sync virtual chain state from a deep chain block after a period of being unsynced. Each call will now return very promptly, but it also means you now have to call GetVirtualChainFromBlock multiple times if you're syncing from a deep chain block.

To take advantage of this new batching mechanism, you only need to make sure that you continue calling GetVirtualChainFromBlock until your software has caught up to the tips of the network. For reference, the pseudo-code is:

startHash = <the_last_hash_you_synced_from>
isCatchingUp = true

// Catch-Up code. Expecting to do faster catch up logic here
while isCatchingUp:
  batch = GetVirtualChainFromBlock(startHash, includeTransactionIds: true)
  // Do your processing with batch
  // ...
  startHash = batch.added[<last_element_index>]

  if len(batch.added) < 10:
    // if the response was batched it will contain at least 10 chain blocks
    // (because we limit the number of merged blocks by mergeset limit x 10),
    // otherwise, we've caught up and can proceed with normal batch processing
    isCatchingUp = false

// Continue your normal pace of processing next batches with GetVirtualChainFromBlock
// ...

What's Changed

• Fix WASM interface typo for normalBuckets and lowBuckets in IFeerateBucket by @Cryptok777 in #557
• Fix new gRPC methods to use camel case (non-breaking change) by @michaelsutton in #560
• virtual chain from block batching. by @D-Stacks in #454
• A few CLI rpc query fixes by @michaelsutton in #563
• Deploy linux binary without musl in its name + various minor miscellaneous things towards v0.15.2 by @michaelsutton in #564

New Contributors

• @Cryptok777 made their first contribution in #557

Stable Mainnet Release & WASM SDK v0.15.1

Kaspa on Rust — Mempool-Focused Release (second stable release)

This version focuses on introducing mempool features required for users and wallets for adopting to fee market conditions.

The main mempool features include:

• Replace-By-Fee (RBF)
• A fee estimation API based on real-time mempool state
• A new mempool evict policy based on fee rate

The version also includes the following major changes:

• Major performance enhancements in the block template transaction selection algorithm. This operation now takes only ~100 microseconds even under heavy load, and that is achieved without compromising on the most profitable selection strategy.
• Important improvement in header processing performance
• Many more accumulated enhancements, improvements and non-critical fixes

It is highly recommended that miners and pools gradually shift to this version both for stability reasons and for better supporting the network under upcoming expected fee market conditions.
