breaking change with 0.7.6 release

[jqnatividad]

With the 0.7.6 release, my project qsv fails to compile with this error:

I fixed it by pinning generator to 0.7.5
dathere/qsv@0f53a4b

Perhaps, 0.7.6 should be yanked and re-released as 0.8.0 instead?

[Xudong-Huang]

you are right, we should use a new major version

[Xudong-Huang]

018b587 would cover this

[Xudong-Huang]

I yanked 0.7.6, thanks

[jqnatividad]

Thanks!
