Tips on how to upgrade dependency: ppxlib to latest version?

[ghost]

Hi I am interested in upgrading the dependency "ppxlib" to v.0.28.0 (the latest version ). Currently bisect_ppx is marked as working with >= 0.21.0 of ppxlib, but in version 0.27.0 onwards the following error manifests:

#=== ERROR while compiling bisect_ppx.2.8.1 ===================================#

I wonder if you have any hints on how best to go about upgrading the dependency?

Sorry it was me who originally submitted this, but I have since shut down the account which I used to create the question. I am still curious about how to resolve this

This particular error was fixed by #400, in which @pitag-ha made Bisect_ppx compatible with ppxlib 0.26.0 and 0.27.0. However, building against ppxlib 0.28.0 still causes other errors. I'll ping this issue once we fix those!
