Metacello 1.0-beta.27.4 released

Metacello 1.0-beta.27.4 has several bugfixes:

  - fix bugs when trying to stash packages and configurations into a
repository.
  - fix Issue 79: http://code.google.com/p/metacello/issues/detail?id=79
"OB-Metacello should use MetacelloMCProjectSpec>>loadVersion: style
default packages instead of lastMetacelloVersionLoad"
  - best fix for Issue 92: http://code.google.com/p/metacello/issues/detail?id=92
"Trait does not understand #isMetacelloConfig"
  - fix Issue 93: http://code.google.com/p/metacello/issues/detail?id=93
"poor error message when failing to resolve a package in a repository"
  - fix Issue 94: http://code.google.com/p/metacello/issues/detail?id=94
"lastVersion vs latestVersion"
  - fix Issue 95: http://code.google.com/p/metacello/issues/detail?id=95
"Infinite project reference loop"

Note that for Issue 94, two new messages have been added:

  - stableVersion replacing latestVersion
  - bleedingEdge replacing lastVersion

#latestVersion and #lastVersion will be deprecated after 1.0 is
released (could be awhile:).


Also, I believe that the Traits issue is resolved and should now
handle any non-class object/instance that masquerades as a class in
the Class pane in OmniBrowser.
