No, the SONAME is the same. ABI should be the same, but I've found
one (more may exist) case where one (probably internal) symbol can't
be found anymore:
Generating secure encryption key. This might take some time..done
cryfs: symbol lookup error: cryfs: undefined symbol:
_ZN8CryptoPP10RandomPool34GenerateIntoBufferedTransformationERNS_22BufferedTransformationERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEy
If I recompile it with the new libcrypto++ release, it is solved.
As this effects cryptography related programs, I want to be extra
safe. The package list for binNMUs:
amule
armory
clementine
codecrypt
cryfs
entropybroker
gdal
murasaki
newlisp
pycryptopp
synergy
tegrarcm
