Bitcoin (BTC) Major Core Update: Key Changes Revealed

U.Today - Bitcoin (BTC), the first and largest cryptocurrency by market capitalization, has welcomed a major new core release, taking a major step forward in its development. Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built.

In a tweet, the Bitcoin development team stated that "a new release candidate of Bitcoin Core, v29.0rc2, is available for testing. This is a new major release and follows v28.0."

As stated, Bitcoin Core v29.0rc2 is a major new release following version 28.0, which was launched in October 2024. This release candidate includes key improvements aimed at enhancing performance, security and overall network efficiency.

What changed?

Part of the mempool policy and mining changes is ephemeral dust, a new concept that allows a single dust output in a transaction, as long as the transaction is zero-fee. To spend any unconfirmed outputs from this transaction, the spender must also spend this dust in addition to any other desired outputs. In other words, this type of transaction should be carried out within a transaction package in which dust is both created and spent at the same time.

Updated settings will also ensure that, as a safety check, Bitcoin Core fails to start if the required parameter value is lower than 2,000 weight units.

The Bitcoin wallet received GUI changes, including the build system, which was migrated from Autotools to CMake: the minimum required CMake version is 3.22.

Low-level changes include newly developed tools and utilities, as well as updated tests and dependencies. A new tool that converts a compact-serialized UTXO snapshot to a SQLite3 database has been added.
