Marcel Taeumel uploaded a new version of ReleaseBuilder to project The Trunk:
http://source.squeak.org/trunk/ReleaseBuilder-mt.206.mcz

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

Name: ReleaseBuilder-mt.206
Author: mt
Time: 26 February 2020, 5:26:15.253527 pm
UUID: 6e9769a8-c40c-e34e-bd56-5627d15b5bdf
Ancestors: ReleaseBuilder-fn.205

Prepare 5.3rc2 --- Renames the two existing change sets to "RootProject" and "HomeProject" to be both readable and file-out compatible. Fixes the (manual) check for undeclared symbols. Make sure that #clearCaches really cleans the code artifacts in the correct order. Adds some documentation for that. Also bumps version from rc1 to rc2.
