Hi guys I created a new Fuel version that includes an important fix (in my opinion). That fix should be integrated into Pharo 2.0 (in my opinion); here's the integration request: https://pharo.fogbugz.com/default.asp?10730 Summary of the change: Changes in the serialized graph during serialization do no longer affect serialization, i.e. the graph serialized it the graph as encountered during analysis. This fix is important for the "Fuel out stack" feature in Pharo2.0 because of contexts that can reference processes (e.g. with Seaside). Since Marcus does not have the capacity to review everything in the inbox, I need one or two poeple to look at the request and green light it. Side note: we need more people to review changes. Simply assigning everything to Marcus doesn't seem to solve this problem :) Thanks for your time. Cheers, Max
