Hi @DanBurton! So sorry for not responding earlier -- I didn't get a notification for this issue. Can you try with the most up-to-date th-test-utils? 1.0.2 should have support up to GHC 8.10

[DanBurton]

Can confirm 1.0.2 builds and passes tests with the latest nightly snapshot. Thanks!

I was able to reproduce this success locally like so:

stack unpack th-test-utils-1.0.2 && cd th-test-utils-1.0.2
echo 'resolver: nightly-2020-06-16' > stack.yaml
stack build --test --bench --no-run-benchmarks --fast
