=== security ===

It was possible to use symlinks and subrepositories to defeat Mercurial's path-checking logic and write files outside a repository. This has been fixed. Users on older versions can either disable subrepositories with {{{[subrepos] allowed=false}}} in their configuration or by ensuring any cloned repositories don't contain malicious symlinks.
