Hi @COrlandella
Thanks for reaching out! We have reviewed this question with our content team and how those dates were determined.
From https://github.com/google/guava/issues/5356, there was a question about Guava EOL versions and an official response from Google stated that "We do not generally backport bug fixes. We encourage users to use the latest compatible version of Guava."
Going by that information, we have reason to consider that only the latest major version and its minor version are supported until the next major version is released.
We use the GA of the current major version as the EOL/OBS of the previous version, and all the minor versions like 30.x and 29.x follows the lifecycle of major version 30.0 and 29.0.
As for 30.x, it will be supported until next major version 31.0 is released. So 30.0 and 30.1 are still on supported. Version 30.0 and 30.1 EOL/OBS dates will be updated to 'To be determined'. This change will be reflected in Technopedia build 20210807.
Let me know if that helps with this question and feel free to reach out if further assistance is required.
Best regards,
Allen
