.. _about-roadmap: ======= Roadmap ======= .. note:: This roadmap is subject to change, but represents the rough direction I plan to go. For specific issues, see the current milestones_. Waffle is already a useful library used in many production systems, but it is not done evolving. Present through pre-1.0 ======================= The immediate future is finishing common segment features and bug fixes. 0.10.2–0.11.x ------------- 0.10.2_ was primarily a docs overhaul with a major fix to how caching works. It was combined with 0.11_. It did include test utilities for consumers. 0.11_ updated support, dropping 1.5 and adding 1.8, and overhauled Jinja integration to be compatible with any Jinja2 helper, like jingo or—more future-proof—django-jinja_. 0.11.1 is probably the last release of the 0.11.x_ series. It added support for Django 1.9 without deprecating any other versions. 0.12 ---- 0.12_ includes a couple of significant refactors designed to pay down some of the debt that's accrued in the past few years. It also includes support for Django 1.10 and above. 0.13 ---- 0.13_ drops support for all versions of Django prior to 1.8, including dropping South migrations (and finally being rid of the old issues with them). Along with that, it changes the way settings are configured to be more modern. 0.13 is about closing some long-standing feature gaps, like segmenting by IP and User-Agent. It also includes finally making a decision about auto-create/data-in-settings. Toward 1.0 ========== There are no solid criteria for what makes 1.0 right now, but after 0.13, most outstanding issues will be resolved and Waffle will be in very good shape. There are no plans for a 0.14, so it seems likely that the next step after 0.13 would be some clean-up and finally a 1.0. Beyond 1.0 ========== *tl;dr: Waffle2 may be a complete break from Waffle.* Waffle is one of the first Python libraries I created, you can see that in the amount of code I left in ``__init__.py``. It is also 5 years old, and was created during a different period in my career, and in Django. There are some philosophical issues with how Waffle is designed. Adding new methods of segmenting users requires at least one new column each, and increasing the cyclomatic complexity. Caching is difficult. The requirements are stringent and no longer realistic (they were created before Django 1.5). The distinction between Flags, Samples, and Switches is confusing and triples the API surface area (Flags can easily act as Switches, less easily as Samples). It is not extensible. Some challenges also just accrue over time. Dropping support for Django 1.4, the current Extended Support Release, would significantly simplify a few parts. There is a simplicity to Waffle that I've always appreciated vs, say, Gargoyle_. Not least of which is that Waffle works with the built-in admin (or any other admin you care to use). I don't have to write any code to start using Waffle, other than an ``if`` block. Just add a row and click some checkboxes. Most batteries are included. These are all things that any new version of Waffle must maintain. Still, if I *want* to write code to do some kind of custom segment that isn't common-enough to belong in Waffle, shouldn't I be able to? (And, if all the core segmenters were built as the same kind of extension, we could lower the bar for inclusion.) If I only care about IP address and percentage, it would be great to skip all the other checks that just happen to be higher in the code. I have rough sketches of what this looks like, but there are still some significant sticking points, particularly around shoehorning all of this into the existing Django admin. I believe it's *possible*, just potentially *gross*. (Then again, if it's gross underneath but exposes a pleasant UI, that's not ideal, but it's OK.) The other big sticking point is that this won't be a simple ``ALTER TABLE wafle_flag ADD COLUMN`` upgrade; things will break. I've been thinking what Waffle would be like if I designed it from scratch today with slightly different goals, like extensibility. Beyond 1.0, it's difficult to see continuing to add new features without this kind of overhaul. .. _milestones: https://github.com/django-waffle/django-waffle/milestones .. _0.10.2: https://github.com/django-waffle/django-waffle/milestones/0.10.2 .. _0.11: https://github.com/django-waffle/django-waffle/milestones/0.11 .. _0.11.x: https://github.com/django-waffle/django-waffle/milestones/0.11.x .. _0.12: https://github.com/django-waffle/django-waffle/milestones/0.12 .. _0.13: https://github.com/django-waffle/django-waffle/milestones/0.13 .. _Gargoyle: https://github.com/disqus/gargoyle .. _django-jinja: https://niwinz.github.io/django-jinja/latest/
