Bitcoin Core Releases New Version for Testing: Details

Key Points

1. The update includes a cap of 2,500 legal sigops per transaction to prevent excessive legacy signature operations.

2. It prevents users on older 32-bit systems from setting high memory values that could impact Bitcoin Core stability.

3. Nodes will avoid using certain network ports like RDP (3389) and VNC (5900) to mitigate security risks.

4. The update follows Bitcoin Core v28.2 and addresses potential DoS impacts on unupgraded miners.
