2.0.0-beta.9

• SECURITY: Fixed integer overflow vulnerability in search tree size
  calculation that could potentially allow malformed databases to trigger
  security issues.
• SECURITY: Enhanced bounds checking in tree traversal functions to return
  proper errors instead of silent failures when encountering malformed
  databases.
• Added validation for invalid prefixes in NetworksWithin to prevent
  unexpected behavior with malformed input.
• Added SkipEmptyValues() option for Networks and NetworksWithin to skip
  networks whose data is an empty map or empty array. This is useful for
  databases that store empty maps or arrays for records without meaningful
  data. GitHub #172.
• Optimized custom unmarshaler type assertion to use Go 1.25's
  reflect.TypeAssert when available, reducing allocations in reflection code
  paths.
• Improved memory mapping implementation by using SyscallConn() instead of
  Fd() to avoid side effects and prepare for Go 1.25+ Windows I/O
  enhancements. Pull request by database64128. GitHub #179.
• Added OpenBytes function for better API discoverability and consistency
  with Open(). FromBytes is now deprecated and will be removed in a future
  version.
