Christoph Thiede uploaded a new version of Compression to project The Trunk:
http://source.squeak.org/trunk/Compression-ct.57.mcz

==================== Summary ====================

Name: Compression-ct.57
Author: ct
Time: 3 January 2022, 7:17:31.519703 pm
UUID: 32eabe2a-30cb-9e45-9820-3f00c262870f
Ancestors: Compression-dtl.55

Fixes ZipWriteStream regression tests. The file stream under test, and thus FastInflateStream, streams bytes rather than chracters, so provide ByteArrays rather than strings as target buffers.
