I am a big believer in rewriting your software from scratch once in a while.

When the world has changed, your needs have changed, your abilities have changed, just patching the existing codebase doesn't cut it.

So today, following recent reflexions, I have started a bottom-up rewrite of Keras, which should be completed in a week or so.

It is intended to be 100% backwards compatible (at least for all documented features). However legacy features will be cleanly separated

@fchollet I’m rewriting some training management tools that rely on the callback infrastructure, and would be curious about direction

@cmyr it will be fully backwards compatible unless you are using undocumented internal features. Callbacks are not affected.

@fchollet I do a bit of non-vanilla stuff; my own class-based version of fit-generator stuff etc. Anyway will hold off pending a peek.
