Hex Files

Bug fixes

• Percent-encode package names, versions and other values in the URLs of API and repository requests, so a /, ?, # or .. in a value can't change the request path

Security fixes

• Fix unpacking a package or docs tarball that contains a GNU sparse file in mix deps.get, mix hex.package fetch --unpack, mix hex.docs fetch and mix hex.docs offline. A sparse file that ends in a hole made the task loop forever, and a sparse hole that crosses a 64 KiB boundary in the file made it fail (GHSA-phm5-m6cj-5382, CVE-2026-96596)
