The version labeled 1.0.3 TLS is dotnet-dev-osx-x64.1.0.0-preview2-003156.pkg (1.0.0? preview?)
The version labeled 1.1 is dotnet-dev-osx-x64.1.0.0-preview2-1-003177.pkg (again: 1.0.0 preview?)
The linux packages have similar pattern.
This allows the team the ability to release new tooling versions (bugfix to the donet command for example), without having to print a new framework version. Same for updating the framework vs the tooling.
On the one hand, it's annoying to keep track of so many versions. On the other hand, it's also annoying to be forced to run a framework update when the only thing that's changed is a command line tool, which may or may not be important to a specific organizations development pipeline.
So, 1.0.0-previewX < 1.0.0.
Semantically this should be read as "1.0.0-previewX is preview X of version 1.0.0"
