Hello,
On September 6th, the platform:f28 module was retired [1] because the issue in MBS described in #1243 [2] was fixed, but due to a miscommunication, MBS was not updated in Fedora's infrastructure to include the fix. Because of this, any modules that buildrequire a module that was built on a retired platform stream but can be installed on any Fedora version, can no longer build. In practice, this occurs with modules that buildrequire the "javapackages-tools" module. To see more of the backstory, you can read #1243 [2].

The purpose of this email is to request a freeze exception to upgrade MBS from v2.25.0 to v2.27.0. 

If this request is denied, I'd like permission to temporarily unretire the platform:f28 stream in the MBS database as an alternative solution. However, this alternative solution will cause any modulemd file that buildrequires all platform streams to trigger a Fedora 28 build which will fail.

Thank you for your help.
