[not-bug] "conan list" prints letter Z instead of a last digit when printing dependency versions e.g. "zlib/1.3.Z" about conan HOT 2 CLOSED

Hi @ViliusSutkus89

this is expected, although it will depend on the options (whether libraries are shared or static). Taking the zlib dependency as an example here.

zlib/1.3.Z means that if that specific binary of glib/2.81.0 was built with zlib/1.3.0, and in the future, zlib/1.3.1 is released - a build in the future where the graph solver considers zlib/1.3.1, will take this binary package as valid ad compatible - this is under "semver" assumptions that a patch release is still fully binary compatible.

This reflects the fact that if both glib and zlib are shared libraries, and zlib/1.3.1 has exactly the same symbols as 1.3.0 - the generated binaries for glib against the new versions would actually be "the same" - so there's no need to rebuild it.

This avoids unnecessary rebuilds (or missing binaries) when new versions are released.

it is a different case when a binary "embeds" the contents of a static library, or header only libraries.

Hello @jcar87 ,

Thanks for the explanation. Somehow I've missed that part in the documentation. I've looked into semver versioning in Conan and thought that this needed to be asked for explicitly. Anyways, sorry for the wrong bug report.
