Have you updated pwb but not the script? The newest version of replace.py shouldn't produce that output.

I searched through the complete repository and don't find any call of 'replaceExcept' which would produce this warning. The usuage in replace.py has been also fixed a few days before the deprecation warning was added:

• Using textlib module specifically: 1a1456157a266707b414d171b3f94e2056f5552e
• Adding deprecation: 5426720bfe83e37aec032e8afcd9470294293ac4
• Merge-base: git merge-base 1a145615 5426720b → 1a1456157a266707b414d171b3f94e2056f5552e (aka 1a145615 is the common ancestor of both patches)
