Changelog

0.8.3

Fix buffer over-read for Zip64 extra fields

Support sync flushes (Z_SYNC_FLUSH in zlib)

Allows for immediate decompression of all pushed bytes

Enables DEFLATE stream concatenation

Fix zip/zipSync when using cross-realm Uint8Array

Improve Zip64 support for streamed or undersized archives

Update performance estimates in README

Fix typings for TypeScript v5.7+

Reduce memory consumption after compression stream completion

0.8.2

Fixed broken UMD build

Fixed edge-case causing skipped data during streaming compression

Fixed bug in GZIP streaming on member boundary

Improved streaming performance on inconsistent chunk sizes

Improved unzip performance on undercompressed archives

Added flushing support into streaming API

Use new ondrain handler and queuedSize

0.8.1

Fixed reallocating on pre-supplied buffer in inflateSync and unzlibSync

Minor documentation fixes

0.8.0

BREAKING: synchronous decompression functions now take an options object rather than an output buffer as a second parameter

inflateSync(compressed, outBuf) is now inflateSync(compressed, { out: outBuf })

Support dictionaries in compression and decompression

Support multi-member files in GZIP streaming decompression

Dramatically improved streaming performance

Fixed missing error on certain malformed GZIP files

0.7.3

Fix folder creation for certain operating system

Removed requirement for setTimeout

Added support for unzip file filters (thanks to @manucorporat: #67)

Fixed streaming gunzip and unzlib bug causing corruption

0.7.0

Improved errors

Now errors are error objects instead of strings
