Since developing ExplicitImports, JuliaSyntax has reached 1.0! 
This however has meant some breaking changes in the syntax tree, which required some updating in ExplicitImports. I have a PR that is JuliaSyntax-1.0-compatible that you can install here:
pkg> add ExplicitImports#eph/js_v1
The branch is now passing all my tests, and I plan to release it as ExplicitImports v1.12 next week.
However in the meantime if you are currently using ExplicitImports in your codebase, if you could test out this branch and verify it still works (e.g. does not start failing your tests) that would be very helpful.
Both success and failure reports are useful, and you can reply here, file an issue on ExplicitImports.jl, on the PR or message me on the open source Julia slack.
