Bitcoin Core version 31.1 release candidate 1 released.

“PR2137 introduces BIP452, which introduces the possibility to share the UTXO set over the P2P layer.

Formosa builds upon BIP-0039 by organizing mnemonic words into themed sentences with syntactic roles (e.g., subject, verb, adjective, object, place). Each sentence draws vocabulary from a coherent semantic domain — medieval fantasy, science fiction, nature, finance, or any custom theme — enabling the user to form vivid mental images that reduce memorization effort per bit of entropy. https://github.com/bitcoin/bips/blob/master/bip-0450.mediawiki
This proposal defines a new tapscript opcode, OP_TWEAKADD, that takes an x-only public key and a 32-byte integer t on the stack and pushes the x-only public key corresponding to P + t*G, where P is the lifted point for the input x-coordinate and G is the secp256k1 generator. The operation mirrors the Taproot tweak used by BIP340 signers and enables simple, verifiable key modifications inside script without revealing private keys or relying on hash locks. https://github.com/bitcoin/bips/blob/master/bip-0449.md

With the support of @TheBlueMatt and Greg Maxwell, w0xlt of Localhost Research has successfully rebased the FIBRE codebase against a modern version of Bitcoin Core.
FIBRE is a specialized patchset on Bitcoin Core that enables a high-speed, low-latency network of nodes to relay blocks across the Bitcoin network near the speed-of-light bound in fiber. In stale block races, large mining operations have an asymmetric advantage. By combining UDP transport, Forward Error Correction (FEC), and Compact Blocks, FIBRE reduces the number of stale block races, thereby minimizing this asymmetry.

Collaborative custody and multisig setups have long faced a tradeoff between safety and privacy. Sharing a key with a third party—whether for recovery, policy enforcement, or convenience—has traditionally meant giving that party visibility into a user’s wallet balance and transaction history.
A new proposal called Chain Code Delegation aims to remove that tradeoff.

In remembrance of the dearly departed we ask that you take a moment to go through the Bitcoin Core v30 Testing Guide.
https://github.com/bitcoin-core/bitcoin-devwiki/wiki/30.0-Release-Candidate-Testing-Guide
Bitcoin Core v30.0 is scheduled to be released on October 10.
https://github.com/bitcoin/bitcoin/releases/tag/v30.0rc2
datacarrier and datacarriersize OptionsPR to undeprecate datacarrier and datacarriersize configuration options has been merged into Bitcoin Core and will be included in v30. The undeprecation simply removes warning messages when using these settings. Many Bitcoin Core Users still desire to use these configuration options and with no clear plan for deprecation it did not make sense to have deprecation warnings.

This release adds support for sending to silent payment addresses. Silent payment addresses are a new form of static payment address, where the actual bitcoin address that you send to is determined from both the silent payment address and the transaction inputs. This means you can pay to the same silent payments address while ensuring bitcoin addresses are never reused. This both simplifies the payment experience and makes it more private, at the cost of increasing the burden on the recipient to scan incoming transactions for payments.
This release also supports BIP353, also known as DNS payment instructions. You can now pay to an address that looks similar to ₿user@domain.com, which resolves to a DNSSEC-signed bitcoin: URI. For privacy reasons it’s best to use only a silent payments address (and BOLT12 invoice) in the URI.
