Sure: http://gemstonesoup.wordpress.com/2011/01/17/metacello-1-0-beta-28-unearthed... Be sure to look at the section of development cycle ... and tools support, too...

Don't let the name 'stable' scare you ... The intent is that the #stable symbolic version specifies the version that should be loaded .... the developer decides which versions are #stable for each platform version and when a new version becomes "the version to use" the developer updates the specification. The users of a configuration shouldn't have to think ... remember in the past the recommended pattern was: ConfigurationOfPharo project latestVersion load and that worked fine until Pharo1.1 and Pharo1.2 were introduced. The expression: (ConfigurationOfPharo project version: #stable) load is intended to replace the use of #latestVersion because it makes it possible to explicitly specify the "latest version" on a platform by platform and platform version basis...

Should we remove invalid and unused versions?

Which ConfigurationOfPharo I should use with Pharo 1.2 ? Cheers.
