v0.1.0b4

Changed

• Minor implementation changes were necessary to make Tiled compatible with
  Numpy 2.0.
• For improved security, the server-side array slicing function has been
  refactored to avoid using eval(). To be clear: there were no known
  exploitable vulnerabilities in the eval() approach. The input was validated
  against a regular expression before being passed to eval(). However,
  avoiding eval() altogether is better practice for defense-in-depth against
  potential code injection attacks due to current or future bugs in Tiled or
  its upstream dependencies.
