Just tried upgrading a project to 2.13.0-rc.4 to see what happens, and found that the old-style fp-ts/lib/ imports in io-ts cause Jest to fail:

Test suite failed to run

ENOENT: no such file or directory, open '[...]/node_modules/fp-ts/lib/lib/Either.js'

  at Runtime.readFile (node_modules/jest-runtime/build/index.js:2574:21)
  at Object.<anonymous> (node_modules/io-ts/lib/Decoder.js:27:22)

It might happen with other packages too (e.g. logging-ts), but it's probably not reached them yet.

Given the project runs successfully (with Node 16.17.0), this could be a Jest problem (or a problem with our configuration), but I thought it worth flagging here.
