Hi Mariano,

One thing I don't understand of Metacello is why don't you use
#latestVersion (or #latestReleaseVersion, #latestDevelopementVersion,
etc) instead of specifying the version number (e.g. '1.3'). How do you
keep updated about the latest version numbers?

This is an excellent question :)

In summary, there is a current problem with Metacello and Pharo: a user of a project doesn't know which is the stable version for a pharo specifc version. For example, in this case suppose FFI 1.1 is the stable for Pharo 1.0 and FFI 1.3 for Pharo 1.1. How can the user know that? there is no easy solution. This is why Dale, me, stef, marcus, esteban, etc, have been discussed last week in ESUG. I will then send a summary about the possible solution.

Anyway, if I use latestVersion, I am not sure you will load that again. Ok....I assumed he was using Pharo 1.1 (because is the current latest stable release). Then, I KNOW that FFI 1.3 works well with Pharo 1.1. If he takes the same image, and in 6 months someone releases FFI 1.4 that doesn't work anymore with Pharo 1.1, then it will fail.

Cheers

Mariano
