Contour 1.1.2.pre not showing up on Bundle Update

I recently pushed contour-1.1.2.pre to RubyGems.

It shows up fine here:

And I can install it using

gem install contour --pre

However it is not showing up when using bundler (I don't think it's a bundler issue):

Bundler accesses the RubyGems API here:

Doing a quick search shows no version 1.1.2.pre of contour (although I'd expect to see it there along with other prerelease versions of contour)

Bundler then fails and gives me:

Could not find gem 'contour (~> 1.1.2.pre) ruby' in the gems available on this machine.

My guess is that contour wasn't added to the rubygems index?

Thanks! Any help appreciated.

    Yanked the gem to see if the index would refresh on the unyank:

    gem yank contour -v1.1.2.pre

    gem yank contour -v1.1.2.pre --undo

    (Did not work...)

    Looks like this is more of a potential issue with RubyGems versioning and my understanding of Semantic Versioning.

    It looks like prerelease is only recognized by RubyGems when the minor number is bumped major.minor.patch-build.

    1.0.0 => 1.1.0.pre

    What apparently fails is:
    1.0.0 => 1.0.1.pre

    So I guess it's my fault for wanting to do a prerelease on a patch level version.

    Is there a reason why patch level pre-releases aren't considered pre-releases by RubyGems?
