How To Use This Tracker

This blog post provides an overview of the updates that have been made over the past week, with a particular emphasis on changes relevant to wallet operations.

Under each network header, releases are formatted as follows:

Bitcoin

Bitcoin Core 24.0 (11/24)

• Adds a new mempoolfullrbf config option that lets users change the policy their node uses for relaying and mining unconfirmed transactions. This option defaults to the existing policy, so no changes occur if the default is used.
• -deprecatedrpc=softforks, -deprecatedrpc=exclude_coinbase, and deprecatedrpc=fees config options have all been removed.
• The getpeerinfo RPC has been updated with a new presynced_headers field.
• /headers/ and /blockfilterheaders/ endpoints now use a query parameter instead of a path parameter to specify result count. The count parameter is now optional, and defaults to 5 for both endpoints. Old endpoints remain functional.
• Guix builds are now reproducible across all architectures.
• The replacable option for the createrawtransaction and createpsbt RPCs now defaults to true.
• The listtransactions, gettransaction, and listsinceblock RPC methods now include a wtxid field for each transaction.

Solana

Testnet v1.14.9 (11/28)

• This is a testnet only release, due to prior mistakes the testnet is currently incompatible with mainnet-beta. This release is part of the solution.
• Cap accounts data a transaction can load by its requested limit

Umee

Umee v3.2.0 (11/27)

• This release is the final step for enabling Gravity Bridge. Slashing is enabled and validators must now run Peggo and must process claims to avoid being slashed.
• The QueryLiquidationTargets RPC is now available when the node is run with --enable-liquidator-query. The Liquidator build flag has been removed. This query should not be enabled for nodes with a public API, as the query involves intensive computation that can impact node stability when used by an attacker.
• IBC is updated to v5.1

Polkadot

Polkadot v0.9.33 (11/28)

• Makes the Multisig Pallet Bounded

Substrate Monthly 2022-12 (11/30)

• Support using ed25519-dalek for historical block tx verification.
