I took revision bumped formulae from previous PR and scanned linkage in Linux bottles to get formulae that will need revision bumps, e.g.

apngasm
  NEEDED       libboost_program_options-mt.so.1.84.0

Also, I was wondering about possibility of unversioning the installed libraries on Linux - #169237 (comment)

On macOS, the above library is unversioned libboost_program_options-mt.dylib

EDIT: Numerous breakages this release due to removal of deprecated APIs.
