A brief update about what to expect from FluidTYPO3 for the next 15 months.
To start with the most important thing: FluidTYPO3 will stay relevant in 2016, for the next TYPO3 LTS as well as future iterations. We will be actively maintaining the project in all of 2016 and of course LTS support will be mandatory - you will always be able to use FluidTYPO3 on the most recent TYPO3 LTS release (but may not be able to use all the most recent FluidTYPO3 features; it is impossible to predict but we will do our very best to provide a consistent experience on LTS and the most recent release of TYPO3).
Later this year, around the release of TYPO3 LTS, we will be hosting a code sprint with focus on perfecting the compatibility with the coming LTS. The code sprint will be in Regensburg, Germany - and of course there will be more information about that as we get closer. Both team members and contributors will attend.
We will then release the result after the code sprint. We can only judge from the current status of development in TYPO3 but it looks like you can expect an upgrade process with minimal, potentially zero issues, if you're coming from the most recent versions of FluidTYPO3.
After this release we may host another code sprint (still undecided). No major releases are planned in 2015 after the LTS compatible release; however, please be aware that we follow a semantic versioning scheme and minor/major releases are determined by features and breaking changes - which means we can't always predict when those releases might happen. As always, we will create bug fix releases as we accumulate fixes.
A site redesign may be coming up but should not affect your existing links; we will take great care to provide long term redirects if any pages should move.
We have applied for a budget in 2016 same as in 2015, for approximately the same amount. The results of this will naturally be published after budget voting ends - but if we are granted a budget, it is planned to have two or three code sprints during 2016 and to provide immediate releases compatible with all coming major/minor versions of TYPO3. The project does not depend on them to stay alive but we happily accept budget grants - and of course donations and contributions of manpower.
Throughout 2016 we will provide regular bug fix releases - with approximately the same frequency as in 2015.
Since we are not currently fully aware of the final feature sets of coming TYPO3 releases, the following information is only theoretical - but the list is limited to only the most probable predictions of what to expect in terms of features associated with FluidTYPO3. Still, you should take this with a grain of salt. All goals may not be reachable or practical, others may change as more and more FluidTYPO3-like behavior gets implemented in the TYPO3 core.
Unfortunately, at this time of writing this, all of these come without references to current status. It makes little sense to link to specific code that is development-only and may change without notice.
Although the Fluid standalone subject deserves a lot of attention and further explanation we still await (a lot more) official communication about what is being done with this project. Until then, your best source of information about that project is the TYPO3Fluid/Fluid GitHub repository, readmes, issues etc.
Overall, the future looks bright!
The FluidTYPO3 team
