This release marks many functions and classes as deprecated with C++ [[deprecated]]
attribute. Warnings can be silenced by defining POCO_SILENCE_DEPRECATED.

Deprecated functionality will be removed in one of the next releases.

source code is modernised in this release.

Bundled software libraries are updated to latest versions:

zlib 1.3.1
expat 2.6.4
pcre2 10.44
libpng 1.6.43
