Marcel Taeumel uploaded a new version of Kernel to project The Trunk: http://source.squeak.org/trunk/Kernel-mt.1526.mcz
==================== Summary ====================
Name: Kernel-mt.1526 Author: mt Time: 27 September 2023, 1:38:59.304019 pm UUID: 9bbe749b-d516-e146-8af2-4f5f7962faa0 Ancestors: Kernel-mt.1525
Fixes regression in DataStream from System-tpr.1411 to make SqueakMap catalog update again. Send #rehash only when the object is complete, not in the middle of a #next call that might be incomplete for cyclic dependencies.
