Hi Dale. For Pharo 1.3 I want to (try) to use all #stable, i.e, I want that ConfigurationOfPharo doesn't explicitly load a specific version of every project but instead, the #stable. First step I need to do (I will try to do it during the weekend) is to update #stable in each of the ConfigurationOf used by ConfuigurationOfPharo. That's an easy part. Now, my question is...I don't really understand how the confs would look like after. I mean, 99% of the cases (in fact, at the beginning it will be 100% until I find a problem), the version I use will be #stable. So,the version of ConfgiruationOfPharo AND all the Configurations used by ConfgiruationOfPharo would look something like this: spec project: 'Autotest' with: #stable; project: 'Autotest Help Tests' with: #stable; project: 'MemoryMonitor' with: #stable; project: 'XMLSupport' with: #stable; I mean...every single project reference will have #stable instead of a specific version. So...is this expected? is this the way I should do it ? Finally...is there a query I can do to Metacello saying "which are the ConfigurationsOf needed for this version for this group of this Conf" ?
