Changes since 0.3.1

  • Now PHP 8.1 ready.
  • PalettedBlockArray::fromData() now performs validation of the provided offset table (words) to ensure that no offset value points to an uninitialized or invalid palette offset. This was mainly a problem with corrupted data loaded from disk, where the palette for a block array was truncated for some reason.
    • Fixes various uninitialized values being returned in cases where offsets pointed outside of the palette.
    • Fixes a bug in 16 bpb that caused memory corruption outside the bounds of the palette when writing a block while the palette was already full. This happened because 16 bits can represent up to 65536 offsets, but the palette size is hard-capped at 4096. When 16 bpb has used all 4096 palette entries, the one used for the replaced block is directly overwritten without validating the offset.
