As previously stated every team will announce in what way it will be affected by the significant phpBB development changes. This post will explain the effects on the modifications team.
Versioning scheme
Since phpBB will be using a new versioning scheme we will adopt this scheme for all of our tools (AutoMOD, UMIL, etc).
MOD authors will be encouraged to use this new versioning system too. We will however be less strict in enforcing it. In fact, we will allow any versioning that is compatible with version_compare, so versions such as 1.0.0.0 will be allowed. We will still require it to be stable though.
Additionally we will release a new version of MODX to support this and adapt our tools where needed.
phpBB 3.0
Because phpBB 3.0 is not going to change we don’t have to adopt any changes. This will just continue as it has been so far.
phpBB 3.x
Depending on what changes will be made to the modding API we will assist MOD authors in using it and provide documentation. All in all, it will highly depend on how many changes will be made to phpBB itself. There are a lots of improvements we can think of, and we will try and get them implemented where possible.
We will allow submission of modifications for new phpBB branches once they are released. We will support the branches that are supported globally.
phpBB 4.0
The release of phpBB 4.0 is way too far ahead for us to be able to say anything at all about it. It is a fresh start and will possibly bring many new possibilities. We can be pretty sure that the new architecture will have an impact on modding that will change it fundamentally. We will wait and see. And work together with the development team.
The future
We have some great plans waiting for the MOD writing community. These include building more advanced infrastructure and tools, as well as making alterations to the MODX standard. We will work on making the workflows of modification engineering more efficient. More information will follow in due time.
