In spite of the communication issue, the point I'd make in support of this arrangement is that historically we've done poorly with code-freezes, or even the lesser strength feature-freezes leading up to a release. A code freeze can be discouraging when integration of new features are delayed and can weaken such the code freeze. Opening the next-version-dev branch when the current-version freezes for release-candidate seems to facilitate pre-release stability - though the risk though of mind-share drifting to the next-version-dev branch needs to be managed. cheers -ben

Hello all, We are preparing to release Pharo 7.0 (which will be in January, as soon as we finish some last details). And in the meantime impatient people has asked (and obtained) the aperture of Pharo 8.0 development! :) So you now can start making Pull Requests against Pharo8.0 branch :) Esteban

Hi, Thanks for the link. For some strange reason, I do not see the linked email in my inbox.

Interesting observation. The linked tools as all other notebook technologies I saw rely on two distinct modes for edit and view that reside in two distinct widgets (editor and viewer). They do that because they simply cannot have it in one. Because of the design of Bloc we are not constrained to that. Instead, we build a seamless interface that is both optimized for viewing, and for editing with live preview that does not rely on an explicit render button. This approach enables direct manipulation without friction, and we think this is a significant advancement in this space. About the remark related "to documents that embed pieces of documents, which embed pieces of documentsâ: It is indeed possible to embed documents in documents, but I am not sure I understand where you see the issue appearing.

We do not regard our work as an evolution, and we are not concerned with backwards compatibility. We are not trying to be completely different to what we had before, but being compatible is simply not a goal. For example, extending oldInspector is usually a matter of a dozen lines. Extending the new Inspector works in a similar way, but with a slightly different API that is needed because of the new infrastructure. The migration is not a pain, and it can happen seamlessly as I described in the mail to Luke. I understand how from your point of view as a user of Pharo and oldGT you regard backward compatibility as important. However, we look at things differently. We think that development can be enhanced both from an efficiency and from a happiness point of view with a significant degree. When something like this is possible, the opportunities are different, too. For example, backward compatibility is about limiting costs. However, when the profit promise can be large, some costs can be worthwhile and are to be considered investments. What do we mean by profit? For example, what would it be worth for a company to have the non-technical people literally pair and understand the internal details of the domain model? Compared to what exists now, that can be invaluable and we think that following moldable development this will be a natural by product. Another example: what would it worth for a developer of a library to build a live documentation with a marginal effort that simply leverages the testing effort? It can be invaluable, and we think this is trivially possible. About the roadmap, here it is: we aim to build a complete development environment that will enable moldable development. We understand how this can appear vague. I think itâs not because I and my colleagues talk about it since many years now. People pay little attention, so now we set ourselves to deliver a concrete incarnation of what we think the future should look like. We set to create something that does not exist in other parts, and we simply do not quite know how this will look like in details. For example, we do know that we want to build a Coder or a Debugger, we even have advanced ideas and implementations, but we do not know exactly how it will look like and because of that we also do not quite know how long it will take. We have a particular way of approaching development that relies on fast feedback and storytelling, and at the end we always get surprised of where the journey takes us. For example, the current state of Documenter was simply difficult to imagine even 4 months ago, and in the process we threw away more code than is now released. So, we will not detail the concrete steps because we do not work like that. We do have a clear vision of what we think software development should be, and we will put forward our guiding principles shortly. About the governance process: GT is built by feenk and will continue to be so for the foreseeable future. We put things that we create in the open, we do so for free, and we welcome people to engage with us. >> To build this alternative we invested in a whole new stack.

As mentioned above, our focus is to build a new experience. It is likely that a typical Pharo user will not have much issues adapting to the new interface. A developer that depended on the old APIs will be somewhat impacted, but we do not expect a too large effort will be required to adopt the new world. Nevertheless, if itâs stability and predictability you are looking for, it is best to wait for now. >> A word about the user experience.
