[bug] Packages using version numbers containing uppercase characters can't be published about docs HOT 2 CLOSED

Hi @asmellby

Thanks for your feedback.

You are right, in this case, it seems that the docs are missing some clarification and explicitly stating the constraint.
Conan 2.0 moved to limit package identifiers to lower case, mostly to avoid name collisions, typo-squatting, or user-confusion. The problem is making foo/1.2.3 different to Foo/1.2.3, as it brings a lot of problems and risks, and making them the same (case-insensitive) brings both implementation challenges and user confusions.

The same happens for foo/1.2.3-Snapshot or foo/1.2.3-snapshot. Making them different versions is problematic and even a security risk, and making them the same is quite challenging and confusing at the least.

So it is intended that all version letters are only lowercase. I will move this ticket to the docs repo to clarify this constraint. Thanks again for your feedback!
