Changes

To improve safety, the game will now detect symbolic links used inside world directory. For a detailed explanation, check our help article.

• If the target of a symbolic link is not on the user-configured allow-list, the game will not proceed with loading the world
  • Note: world directory itself can still be linked
• The list of allowed symbolic link targets is stored in file allowed_symlinks.txt in client or server top directory
• The file consists of entries (one per line) with following formats allowed:
  • Lines starting with # are comments and are ignored
  • [type]pattern, where type can be glob, regex or prefix
    • prefix matches start of path with given pattern (so for /test paths /test, /test/ and /test/foo.txt would match)
    • regex matches regular expression against whole path
    • glob uses OS-specific path matching mechanism (for example *.txt would usually match files with txt extension)
    • Note: paths will use OS-specific separators
  • pattern, which uses default prefix type
