Chris Muller uploaded a new version of ReleaseBuilder to project Squeak 4.5:
http://source.squeak.org/squeak45/ReleaseBuilder-cmm.110.mcz

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

Name: ReleaseBuilder-cmm.110
Author: cmm
Time: 26 January 2014, 10:21:03.554 pm
UUID: 5afb9b3e-8e39-477a-be16-fbfaeb41a183
Ancestors: ReleaseBuilder-cmm.109

- #prepareNewRelease prepares the image pointing to the release repository, not Trunk.
- By contrast, the daily non-release builds appropriately point to the #buildRepository, Trunk.
- Be explicit about clearing MC passwords for a publicly-consumed build.
