@mikethompson: Ah, gotcha. I was trying r/track out to hopefully get the benefits of cached computation, but it still seems to trigger all dependent reactions when you deref.

@seantempesta: the upcoming v0.8.0 has de-duplicated subscriptions which will be nice.

Any idea on when that’ll be released?

I would hope to see a beta within a week

There's an alpha1 available which provides def-sub already

I'm just waiting to complete the Effectful handlers stuff

That will be alpha2

0.8.0-alpha1 contains breaking changes: https://github.com/Day8/re-frame/blob/master/CHANGES.md#080--201607xxxx Be aware that things marked with XXX are not yet complete (hence alpha1).
