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, 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 now detects symbolic links used inside world directory.
  • If the target of a symbolic link is not on the user-configured allow-list, the game does 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 use OS-specific separators.
    • pattern, which uses default prefix type.

Fixes

1 issue fixed

From released versions before 1.20

• MC-257778 – Bamboo Mosaic Slabs and Stairs are not in the #slabs and #stairs block and item tags.
