depends: libxcb-util 0.4.1
What changed, and why it matters
This commit updates a build dependency, libxcb-util, from version 0.4.0 to 0.4.1 in Bitcoin Core's packaging system. It only changes the version number and the expected file hash (SHA-256) used to verify the downloaded source. There is no direct evidence in the commit that this fixes a security vulnerability, but dependency updates can sometimes include upstream bug or security fixes. Without external references, the security relevance is unclear.
Treat as a routine maintenance update. Review upstream libxcb-util 0.4.1 release notes for any security advisories before deciding whether to prioritize deployment. No immediate action is warranted based solely on this commit.
Security signals we found

Evidence from the diff
The commit modifies depends/packages/libxcb_util.mk to bump libxcb-util from 0.4.0 to 0.4.1 and updates the corresponding SHA-256 checksum. This is a routine dependency version bump in Bitcoin Core’s depends build system. The diff does not describe the reason for the update, any CVE, or any specific security issue. libxcb-util is an X11/XCB utility library used in the GUI build path, not in consensus or networking code.
