## 1.0.2

### Patch Changes

- ⚠️ Fix tar and multipart cases that used UTF-16 instead of UTF-8 length calculations
  Submitted by [@kitten](https://github.com/kitten) (See [#33](https://github.com/expo/multitars/pull/33))
- Enforce declared `File` sizes for multipart/tar outputs, to avoid corrupted tarballs
  Submitted by [@kitten](https://github.com/kitten) (See [#31](https://github.com/expo/multitars/pull/31))
- Close stream iterators after streams are done
  Submitted by [@kitten](https://github.com/kitten) (See [#35](https://github.com/expo/multitars/pull/35))
- ⚠️ Fix multipart corruption when headers match limit exactly
  Submitted by [@kitten](https://github.com/kitten) (See [#38](https://github.com/expo/multitars/pull/38))
- Don't ignore PAX zero-size override
  Submitted by [@kitten](https://github.com/kitten) (See [#32](https://github.com/expo/multitars/pull/32))
- ⚠️ Fix incorrect combined header limit being applied
  Submitted by [@kitten](https://github.com/kitten) (See [#34](https://github.com/expo/multitars/pull/34))
- ⚠️ Fix tar input's header being concurrently readable with a cancellation padding skip. This meant that partially reading a file may have caused issues and misalignment on the next file access
  Submitted by [@kitten](https://github.com/kitten) (See [#28](https://github.com/expo/multitars/pull/28))
- ⚠️ Fix fallback conversion when `Symbol.asyncIterator` isn't available
  Submitted by [@kitten](https://github.com/kitten) (See [#29](https://github.com/expo/multitars/pull/29))
- Stop symlink `entry.size === 0` from being used for padding, corrupting the output
  Submitted by [@kitten](https://github.com/kitten) (See [#30](https://github.com/expo/multitars/pull/30))
- Apply global PAX size override to all following entries
  Submitted by [@kitten](https://github.com/kitten) (See [#39](https://github.com/expo/multitars/pull/39))
- ⚠️ Fix tar outputs with leading slash above length limit miscomputing prefix
  Submitted by [@kitten](https://github.com/kitten) (See [#27](https://github.com/expo/multitars/pull/27))
- ⚠️ Fix shared `Uint8Array` on CRLF bytes causing `workerd` regression
  Submitted by [@kitten](https://github.com/kitten) (See [#41](https://github.com/expo/multitars/pull/41))
- Restore performance (after regression due to size limit) by decreasing async generator layering overhead
  Submitted by [@kitten](https://github.com/kitten) (See [#40](https://github.com/expo/multitars/pull/40))
