Update to d3 seems to have broken epoch

See changelog here: https://github.com/d3/d3/releases

v3.5.17 seems to be the last one that works.

Seconding this. After updating d3 to v4, epoch doesn't work since it uses d3.time.format, etc.

Thanks in advance!

I take it that Epoch requires D3js < v4, from the above. Is the upgrade to v4 compatibility on the roadmap? Would be a handy thing to add to the docs, me thinks. Being new to Epoch, didn't think about at first and spent a little time wondering why it wasn't working.

The documentation lays out how to fix the time issue.

I've done this locally and it works. There are other issues so as @zerosquadron asked, is there a roadmap for a d3 v4 rework?

@beauremus - If you have fixed it locally, why not open a PR? I haven't had much time to work on Epoch as of late but I totally have time to review a PR or two 👍
