1.20 Pre-release 7 (known as 1.20-pre7 in the launcher) is the seventh and final pre-release for Java Edition 1.20, released on May 29, 2023,[1] which adds symbolic link validation, and fixes a bug.

Changes[]

General[]

Tag
  • Added bamboo_mosaic_slab to #slabs block and item tags.
  • Added bamboo_mosaic_stairs to #stairs block and item tags.
General
  • To improve safety, the game will now detect symbolic links used inside world directory.
    • 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.
