Rubygems release 3.12.0 differs from github release version

[mikelorant]

Checking the code for the tag of the Ruby release 3.12.0 shows the following:

s.required_ruby_version = '>= 2.3'

https://github.com/protocolbuffers/protobuf/blob/v3.12.0/ruby/google-protobuf.gemspec

However download the Gem from Rubygems shows:

s.required_ruby_version = Gem::Requirement.new([">= 2.5".freeze, "< 2.8.dev".freeze])

This is causing issues with applications dependent on this such as aws-fluent-plugin-kinesis.

ERROR:  Error installing fluent-plugin-kinesis:
	google-protobuf requires Ruby version < 2.8.dev, >= 2.5.

It appears that RubyGems rewrites our gemspec when the gem is uploaded.

However the rewritten gemspec is arguably more correct, as we dropped support for binary gems for Ruby <2.5: #7453. It had become impossible to build our gem on these versions. Also upstream dropped support for Ruby 2.3 on 2019-03-31 and Ruby 2.4 on 2020-03-31.

This is mentioned in the changelog for Ruby:

https://github.com/protocolbuffers/protobuf/releases/tag/v3.12.0

Sorry to hear this is causing problems for you. If you are still on an older version of Ruby is it possible to keep using the older version of protobuf?

Thanks for the explanation. Closing the issue.

Ruby 2.3 and 2.4 are supported again in 3.12.1.
