1. Mercurial 4.9 (2019-02-01)

An overview of new features available. This is a regularly-scheduled quarterly feature release that also contains security fixes.

1.1. 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.

1.2. commands
