According to Odaily, Bitcoin Core's Optech Newsletter #306 has recommended users to upgrade to Bitcoin Core 25.0 or a higher version within the next two weeks, with the latest version being 27.0. This advice comes as part of a discussion among several Bitcoin Core project members regarding a new policy on vulnerability disclosure.

Under this new policy, low severity vulnerabilities will be disclosed approximately two weeks after the release of a new version. Most other vulnerabilities, on the other hand, will be disclosed after the affected versions have expired. This move is seen as a proactive measure to ensure the security and integrity of the Bitcoin Core system.

Users are therefore urged to upgrade to the latest version of Bitcoin Core to benefit from the latest security updates and to protect their digital assets from potential vulnerabilities. The Bitcoin Core team is committed to maintaining the highest level of security for its users and this new policy is a testament to that commitment.
