0.3.5

• Enable vectorizing optimizations to significantly improve performance of validation in PalettedBlockArray::fromData().

0.3.4

Changes since 0.3.3

• Fixed LightArray::isUniform() incorrectly returning false for arrays which were uniform with a non-zero value.
• Slightly improved performance of PalettedBlockArray::getPalette().

0.3.3

Changes since 0.3.2

• Fixed bogus corruption errors due to non-zero bits in 3, 5 and 6 bits-per-block PalettedBlockArrays.
• Fixed memory corruption and assert failures in the following methods (now ignoring all but the final 4 bits in the coordinates given):
  • PalettedBlockArray::get()
  • PalettedBlockArray::set()
  • LightArray::get()
  • LightArray::set()

0.3.2

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.

0.3.1

Changes since 0.3.0

• Fixed a bug in PalettedBlockArray's garbage collection. If the bits-per-block of a palette was too high, but the palette had no holes, GC would not take place.

0.3.0

Changes since 0.2.0

• PHP 8.0 is now required as a minimum.
• Added support for 0-bits-per-block palettes (readiness for Minecraft Bedrock 1.18).
• Added LightArray->isUniform(), which tells if the light array only contains the given unique value.
• Fixed SubChunkConverter::convertFromLegacyColumn() not checking bounds of the yOffset parameter.
