Spring PDF version of Spring documentation is not available for latest versions

Affects: 6.0.9-6.1.8

---

It seems that starting from version 6.0.9 the PDF version of Spring reference is not available for download here:

https://docs.spring.io/spring-framework/docs/

e.g. https://docs.spring.io/spring-framework/docs/6.1.8/reference/pdf/spring-framework.pdf doesn't exist.

Is it due to an error or intentional?

PDF versions of the documentation are not built since we moved to Antora in #30414. It's not currently possible to generate a PDF for our documentation, but it might be in the future. We'll mostly follow Spring Boot's lead here, so I'm closing this issue in the meantime.
